نکاتی مفید در مورد تنظیم php.ini

تنظيم متغيرهاي مربوط به توسعه ها
متغير هاي مربوط به توسعه ها، در بخش جداگانه اي از فايل پيکربندي (php.ini) ذخيره مي شوند. براي مثال تمام متغيرهايي که به توسعه هاي MySQL مربوط مي شوند بايد در قسمت [MySQL] در فايل php.ini، قرار بگيرند.

اگر قصد استفاده از تابع mail در PHP را داريد، 3 متغير وجود دارد که بايد آنها را تنظيم کنيد. متغيرهاي SMTP و sendmail_from (در ويندوز) يا sendmail_path (در يونيکس) در هنگام ارسال e-mail از طريق تابع mail مورد استفاده قرار مي گيرند. در ويندوز اين متغير ها براي تنظيم SMTP Server و همچنين براي تعيين آدرس From در ساختار e-mail به کار مي روند. در يونيکس متغير sendmail_path مسير MTA يا Mail Transfer Agent را براي ارسال mail تنظيم مي کند.

SMTP = myserver.localnet.com
sendmail_from = [e-mail]
sendmail_path = /usr/sbin/sendmail

متغيرهاي java.class.path ، java.home، java.library و java.library.path همگي آدرس کلاس ها و کتابخانه هاي جاوا را تنظيم ميکنند. اين مقادير به وسيله توسعه هاي جاوا مورد استفاده قرار مي گيرند. بنابراين اگر مي خواهيد PHP بتواند ارتباط صحيحي با برنامه هاي جاواي شما برقرار کند از درستي و معتبر بودن مقادير اين متغير ها اطمينان حاصل کنيد.

java.class.path = .\php_java.jar
java.home = c:\jdk
java.library = c:\jdk\jre\bin\hotspot\jvm.dll
java.library.path = .\

متغير session.save_path مشخص کننده آدرس شاخه موقتي است که براي ذخيره اطلاعات session ها بکار مي رود. معمولا اين متغير به طور پيش فرض مقدار /tmp را دارد، اما از آنجا که اين شاخه در ويندوز وجود ندارد بايد آن را با آدرس درست شاخه موقت ويندوز تصحيح کنيد در غير اين صورت هنگام فراخواني دستور session_start با خطا مواجه مي شويد. همچنين مي توانيد با تنظيم متغير session.cookie_lifetime مدت اعتبار cookie هاي session را بر حسب ثانيه مشخص کنيد.

session.save_path = c:\windows\temp
session.cookie_lifetime = 1800

تنظيمات مربوط به امنيت
تعدادي متغير در php.ini وجود دارد که به امنيت PHP نصب شده بر روي سيستم شما مريوط مي شوند. مهمترين آنها متغير safe_mode مي باشد که به طور مثال استفاده از آن براي محدود کردن آنچه کاربر مي تواند از طريق PHP انجام دهد بهISP ها توصيه ميشود.

safe_mode = Off

اگر safe mode فعال باشد (safe_mode = on) مي توانيد با تنظيم متغير safe_mode_include_dir مشخص کنيد که کدام شاخه ها براي فايل ها مورد جستجو قرار بگيرند. همچنين ميتوانيد نوع برنامه هايي که کدهاي PHP مي توانند از طريق فرمان exec آنها را اجرا کنند، را محدود کنيد. بدين منظور بايد اين برنامه هاي مجاز را در يک شاخه مخصوص قرار دهيد و از طريق متغير safe_mode_include_dir به PHP بگوييد که تنها در آن شاخه به دنبال آنها بگردد.بدين ترتيب تنها برنامه هاي درون اين شاخه توسط فرمان exec قابل دسترس خواهند بود.

safe_mode_include_dir = /usr/local/lib/php/safe-include
safe_mode_exec_dir = /usr/local/lib/php/safe-bin

شما مي توانيد اعمال مربوط به فايل ها را از طريق متغير open_basedir محدود کنيد. آدرس نسبت داده شده به اين متغير به عنوان ريشه اصلي (root) براي اعمال مربوط به فايل ها به کار مي رود. وقتي که اين متغير مقدار مي گيرد فايلهايي که در ساختار درختي اين ريشه نباشند براي PHP غير قابل دسترس خواهند بود. اين روش مناسبي براي محدود کردن کاربران يک سيستم اشتراکي مي باشد تا آنها تنها به آدرسهاي مربوط به خودشان دسترسي داشته باشند.

open_basedir = /home/web/

متغير max_execution_time تعيين ميکند که PHP حداکثر چند ثانيه منتظر پايان يافتن يک کد باشد قبل از آنکه به اجبار آن را خاتمه دهد. وقتي کد شما گرفتار حلقه هاي بينهايت ميشود اين متغير بکار مي آيد.اگر چه ممکن است اين موضوع گاهي مزاحمت ايجاد کند مثلا زماني که کد نوشته شده نياز به انجام اعمال زمانبري دارد، مثلا upload کردن يک فايل حجيم. در اين مواقع بايد مواظب باشيد که اين مقدار را افزايش دهيد تا مانع آن شويد که PHP اجراي کد شما را در وسط يک کار مهم خاتمه دهد.

max_execution_time = 90

تنظيمات مربوط به upload فايل ها و متغير هاي فرمها
اگر پيکربندي هاي امنيتي که تاکنون ذکر شد کافي نيست باز هم مي توانيد با غير فعال کردن قابليت upload فايل از طريق متغير file_uploads، يا با محدود کردن حداکثر حجم قابل upload از طريق متغير upload_max_filesize سيستم خود را از اين هم امن تر کنيد. اغلب تمايل خواهيد داشت که فضاي کوچکي را براي upload فايلها اختصاص دهيد مگر اينکه برنامه اي داشته باشيد که قرار باشد فايل هايي نظير يک گالري عکس يا يک FTP Service را پذيرا باشد.

file_uploads = On
upload_max_filesize = 2M

اگر تمايلي به upload کردن فايلها نداريد اما از تعداد زيادي فرم در صفحات PHP تان استفاده ميکنيد، 2 متغير ديگر وجود دارد که بايد برايتان جالب باشد. اول متغير register_globals، علت بيشترين سردردهاي برنامه نويسان با سابقهPHP در PHP 3.x اين متغير به طور پيش فرض فعال بود (on) که موجب ميشد وقتي يک فرم submit مي شد متغيرهاي آن بطور اتوماتيک به متغيرهاي PHP تبديل شوند.
مسايل امنيتي موجب شد که در PHP 4.x اين متغير بطور پيش فرض غير فعال باشد. (off). در نتيجه متغيرهاي فرم تنها به کمک آرايه هاي ويژه $_GET و $_POST قابل دسترس باشند. اين امر خيلي از کدهاي نوشته شده با PHP 3.x را با مشکل مواجه ساخت. مثلا مقداري که در يک فيلد وارد شده بود در PHP 3.x با $email قابل دسترس بود در حالي که در PHP 4.x با $_POST[email] يا $_GET[email] ميتوان به آن رجوع کرد.
ميتوانيد اين متغير را غير فعال کنيد (off) تا امنيت بيشتري را در برابر حملاتي که از طريق فرمها صورت مي گيرند برقرار کنيد. به منظور سازگاري با کدهاي نوشته شده با PHP 3.x آن را فعال کنيد:

register_globals = on

متغير ديگري که به کار با فرم ها مربوط ميشود post_max_size است که کنترل مي کند حداکثر چه حجم داده اي توسط متد POST يک فرم پذيرفته شود. به نظر نمي آيد که زماني لازم شود اين مقدار را از 8 MB افزايش دهيد. در عوض احتمال دارد بخواهيد آن را به يک مقدار واقعي تر تغيير دهيد. به هر حال اگر قصد داريد از امکانات upload فايل در PHP استفاده کنيد اين مقدار را بيشتر از مقدار متغير upload_max_size قرار دهيد.

post_max_size = 8M

يک متغير جديد هم در PHP 5 معرفي شده است: max_input_time. که حداکثر زمان بر حسب ثانيه که عمل دريافت داده هاي ورودي از طريق POST ،GET و PUT مي تواند طول بکشد را مشخص مي کند. اگر برنامه شما تحت يک اتصال کند اجرا مي شود بهتر است اين مقدار را افزايش دهيد تا به برنامه اجازه دهيد مدت بيشتري را به دريافت داده هاي ورودي اختصاص دهد.

max_input_time = 90

افزايش کارآيي
هنوز مقادير ديگري هم وجود دارد که با دستکاري آنها مي توانيد کارايي مفسر PHP را بالا ببريد. به منظور جلوگيري از اجراي کدهايي که ممکن است تمام حافظه موجود سيستم را اشغال کنند، PHP به شما اجازه مي دهد که براي استفاده از حافظه محدوديتي معين کنيد. اين کار از طريق متغير memory_limit قابل انجام است که حداکثر ميزان حافظه قابل استفاده توسط يک برنامه واحد را مشخص مي کند.

memory_limit = 8M

مقدار متغير memory_limit اغلب بايد از مقدار متغير post_max_size بيشتر باشد.
مساله ديگري که با دانستن آن مي توانيد کارايي را افزايش دهيد غير فعال کردن متغيرهاي $argc و $argv است که تعداد و محتواي آرگومان هاي خط فرمان که به يک برنامه ارسال شده اند، را مشخص مي کنند.

register_argc_argv = false

همينطور غير فعال کردن آرايه هاي $HTTP_GET_VARS , $HTTP_POST_VARS . چرا که به احتمال زياد در دنياي جديد $_GET , $_POST ديگر نيازي به آنها نيست. غير فعال کردن اين اجزا باعث بهبود کارآيي مي شود البته فقط در PHP 5 و از طريق متغيرregister_long_arrays قابل انجام است.

register_long_arrays = false

تابع ini_set
و در آخر نکاتي در مورد تابع ini_set. در حالي کهPHP تمام تنظيمات اش را در هنگام بالا آمدن، از فايل php.ini مي خواند، اين اجازه را به شما مي دهد که اين تنظيمات را به کمک تابع جالب ini_set و در برنامه خود انجام دهيد. البته اين تغييرات فقط براي همان برنامه اي که در آن از تابع ini_set استفاده کرده ايد اعمال مي شوند .اين تابع 2 آرگومان مي گيرد: نام متغير پيکربندي اي که مي خواهيد مقدارش را تغيير دهيد و مقدار جديد آن. اين هم يک مثال که حداکثر زمان اجراي مجاز براي برنامه اي که اين کد در داخل آن نوشته شده است را افزايش مي دهد.



ini_set('max_execution_time', 600);

// more code

?>

باز هم يادآوري مي شود که اين تنظيمات در داخل هر برنامه اي که نوشته شود فقط همان برنامه را تحت الشعاع قرار مي دهد. وقتي که برنامه خاتمه پيدا کند مقدار متغير به طور اتوماتيک به مقدار اوليه تغيير خواهد کرد.

اگر برنامه هايPHP شما بر روي يک سرور مشترک (Shared Server) اجرا مي شوند احتمالا شما دسترسي به فايل پيکربندي php.ini نخواهيد داشت. در اين موارد تابع ini_set کمک شاياني مي کند. چرا که اجازه مي دهد تنظيمات مورد نظرتان را براي برنامه هاي خودتان اعمال کنيد

نکاتی مفید در مورد تنظیم php.ini

فايل پيکربندي PHP
قبل از شروع مطالب نگاهي اجمالي به ويژگيهاي فايل پيکربندي PHP منطقي به نظر مي رسد. نام اين فايل php.ini مي باشد و به دلايلي از ساختار کلي فايلهاي ini که بيشتر در برنامه هاي کاربردي ويندوز استفاده مي شود، پيروي مي کند. اين فايل متني به صورت ASCII مي باشد که به بخشهايي (session) تقسيم مي شود. هر بخش متغيرهايي را که مربوط به آن بخش مي شوند، در بر مي گيرد. هر بخش چيزي شبيه زير مي باشد:

[MySection]
variable=\"value\"
anothervariable=\"anothervalue\"

نام بخش در يک جفت براکت"[]" در بالا قرار مي گيرد. و زير آن در هر سطر يک متغير با مقدارش قرار مي گيرد. متغيرها به حروف حساس (case sensitive) هستند و نمي توانند شامل فاصله (space) باشند، در حالي که مقادير متناظر آنها مي توانند اعداد، رشته کاراکتري (string) و يا Boolean باشند.

سمي کالن ";" در ابتداي هر سطر به عنوان نشانگر درج توضيحات (comment) مي باشد. اين راهي ساده براي فعال يا غيرفعال کردن ويژگيهاي PHP مي باشد، به جاي حذف کردن يک سطر مي توانيد به اين روش آن را به توضيح تبديل کرده که در پردازش فايل ها شرکت نخواهد کرد. در صورتي که فکر مي کنيد ممکن است بعد ها بخواهيد از ويژگي که اکنون به کارتان نمي آيد، استفاده کنيد بهتر است آن را پاک نکنيد.

براي اينکه PHP بتواند فايل php.ini را تشخيص بدهد بايد آن را در دايرکتوري جاري، دايرکتوري که در متغير $PHPRC تعريف شده، يا دايرکتوري که هنگام کامپايل مشخص شده است(براي ويندوز اين همان دايرکتوري اصلي PHP است) نگهداريد.

بعد از اينکه شما تغييراتي در فايل php.ini داديد براي آنکه تغييرات اعمال شوند بايد سرور خود را مجددا راه اندازي نماييد (سرور را restart کنيد). البته فرض بر اين است که شما قبلا در حال استفاده PHP بر سرور خود بوده ايد. براي استفاده هاي command-line از PHP فايل پيکربندي php.ini در هرباري که برنامه PHP احضار مي شود خوانده و چک مي شود.


تنظيم ويژگيهاي مفسر
اولين مرحله در اين مقاله از مهمترين گامهاي آن مي باشد، ويژگيهايي که به مفسر زبان PHP مربوط مي شود. اولين مورد در اينجا engine variable مي باشد که چک مي کند که PHP engine بايد فعال "on" يا غير فعال "off" باشد. Off کردن اين متغير به معني اين است که کدهاي PHP توسط سرور تفسير نشوند.معمولاً نيازي به اين تغيير حس نمي شود، پس اين متغير را به صورت on رها کنيد.

engine=On

متغير short_open_tag کنترل مي کند که آيا مفسر بايد تگهاي کوتاه را همانند تگ استاندارد تشخيص دهد يا نه.در صورتي که تشخيص مي دهيد اين نمونه تگها باعث ناسازگاري با ديگر زبانها مي شوند يا اينکه تصميم به استفاده از قوانين syntax مختص PHP داريد مي توانيد آن را off کنيد.

short_open_tag = On

معمولاً session, cookie و اطلاعات HTTP header در يک اسکريپت PHP بايد قبل از توليد هرگونه خروجي توسط آن اسکريپت فرستاده شوند. در صورتي که اين در برنامه شما امکان پذير نيست مي توانيد هر چه را که PHP به نام output buffering مي شناسد، توسط متغيرهاي output_buffering فعال کنيد.

با on بودن output buffering، زبان PHP خروجي اسکريپت شما را در يک بافر مخصوص نگه مي دارد و هنگامي آنها را مي فرستد که به طور مشخص به آن دستور داده شود. اين به شما امکان مي دهد که cookieها يا اطلاعات HTTP header را از وسط يا انتهاي کد اسکريپت خود بفرستيد. هرچند اين مي تواند کارآيي را در حاشيه کاهش دهد.

output_buffering = Off

شما مي توانيد با يک عدد به عنوان مقدار براي متغير output_buffering اندازه بافر را تعيين کنيد.

output_buffering = 2048

هنگامي که PHP شروع به کار مي کند يک پيام حاوي شماره نسخه خود به هدر استاندارد سرور مي افزايد.براي غيرفعال کردن آن مي توانيد متغير expose_PHP را off کنيد.اين مي تواند مفيد باشد، مثلا اگر بخواهيد امکانات وب سرور خود را از ديد هکرها پنهان کنيد.

expose_PHP = On

تنظيم مسير جستجوي
شما مي توانيد مسير جستجويي را براي PHP با تنظيم متغير include_patch که ليستي از مسيرها را مي پذيرد، مشخص کنيد. PHP هنگامي که با فايلي که مسير آن مشخص نشده است ، مواجه مي شود به طور اتوماتيک اين مسيرها را چک مي کند.
اگر شما کتابخانه اي از توابع يا مجموعه اي از کلاسها داريد که زياد از آنها استفاده مي کنيد مي توانيد دايرکتوري موقعيت آنها را در اين متغير قرار دهيد. همچنين اين متغير مکان مناسبي براي اضافه کردن دايرکتوري PEAR خود PHP مي باشد، که مجموعه اي از کلاسهايي که بسيار استفاده مي شوند را شامل مي شود.

include_path = \".:/usr/local/lib/php/pear:\"

کاربران ويندوز براي مشخص کردن چندين دايرکتوري بايد از سمي کالن";" بين آنها استفاده کنند و کاربران unix از کالن ":".

دو متغير جالب در اين زمينه auto_prepend_file و auto_append_file مي باشند. اين متغيرها فايلهايي را مشخص مي کنند که PHP به ابتدا يا انتهاي هر سند PHP اضافه خواهد کرد. اين مورد بيشتر براي اضافه کردن header و footer به صفحاتي است که توسط PHP ايجاد مي شوند، به طوري که باعث مي شود تعدادي خط کد به هر سند PHP که شما مي نويسيد اضافه گردد.
اين فايلها هم مي توانند اسکريپتهاي PHP و هم html معمولي باشند، ولي کدهاي PHP براي اين امر بايد در تگ استاندارد محصور شده باشند.

auto_prepend_file = /home/web/includes/header.php
auto_append_file = /home/web/includes/legal.php

چگونگي رفتار با خطاها
خطا ها در PHP در چهار دسته مي آيند: parsing errors يا خطاي زمان تجزيه (کامپايل)، تذکرات درمورد خطاهاي موجود در کد مثلا مقدار دهي نکردن يک متغير، warning يا هشدار و fatal error. معمولا هنگامي که PHP با يکي از خطاهاي parsing error يا warning يا fatal error مواجه مي شود، خطاها را نمايش مي دهد و اگر خطا از نوع fatal error باشد اجراي اسکريپت را در همان نقطه متوقف مي کند. شما مي توانيد اين رفتار را با متغير error_reporting که چند فيلد خطا را مي گيرد و تنها خطاهايي را که با آنها سازگار باشند نمايش مي دهد، اصلاح کنيد.

error_reporting = E_ALL

براي غير فعال کردن نمايش خطاها مقدار متغير display_errors را به نادرست تغيير دهيد و به جاي آن پيام خطاها را در ثبات خطاها از طريق متغير log_errors بنويسيد.
انجام اين کار براي امنيت بيشتر مفيد است، با غيرفعال کردن نمايش خطا شما اطلاعات ويژه سيستم خود را مخفي مي کنيد بدون توجه به اينکه آيا کاربران قصد خراب کردن سايت شما را دارند يا فقط استفاده مي کنند.به جاي آن شما بايد خطاها را در يک فايل دلخواه يا ثبات خطاي سيستم (system logger)، با تنظيم مقدار متغير error_log به مسير فايل انتخابي يا مقدار پيش فرض "syslog"، ثبت کنيد. فقط به ياد داشته باشيد که مرتبا به اين فايل سربزنيد تا ببينيد که در برنامه شما چه خطاهايي وجود دارد.

display_errors = Off
log_errors = On
error_log = \"error.log\"

فعال کردن توسعه ها
توسعه هاي متعددي براي PHP موجود است. در سيستمهاي يونيکس لازم است که اين توسعه ها در زمان کامپايل ساخته شوند. در ويندوز، dll هاي باينري وجود دارند که بايد ضميمه شوند. متغير extension_dir محتوي نام شاخه اي است که PHP در آن به دنبال اين توسعه ها مي گردد. مثلا:

extension_dir = \"C:\Program Files\Internet Tools\Apache\bin\php4\extensions\"

نسخه ويندوز PHP به همراه ۲۰ توسعه منتشر مي شود که تمامي آنها در فايل php.ini ليست شده اند. براي فعال کردن هر توسعه، علامت سمي کالن جلوي آن را حذف کرده و سرور خود را از نو راه اندازي کنيد. براي غير فعال کردن يک توسعه نيز مي توانيد جلوي آن علامت سمي کالن رو اضافه کنيد.

اگر توسعه مورد نظرتان در ليست توسعه ها در فايل php.ini نيست از متغير extension استفاده کرده و نام dll مورد نظر را به آن نسبت دهيد. مثلا:

extension=php_domxml.dll
extension=php_dbase.dll

لیست کامل پورتهای TCP / UDP

Well-known ports: 0–1023
According to IANA "The Well Known Ports are assigned by the IANA and on most systems can only be used by system (or root) processes or by programs executed by privileged users. Ports are used in the TCP [RFC793] to name the ends of logical connections which carry long term conversations. For the purpose of providing services to unknown callers, a service contact port is defined. This list specifies the port used by the server process as its contact port. The contact port is sometimes called the "well-known port"."[1]

1023 TCP UDP Reserved[1] Official

[edit] Registered ports: 1024–49151
Only those ports that are commonly used are listed; for full list, refer to the IANA port list.[1]

When investigating TCP traffic, be careful not to confuse the client and server ports. The client port is incremental, typically beginning at 1024 at boot time and wrapping at 4096. If the port you are investigating is in the lower part of this range, it may be a client port. Stateful firewalls identify the server port, but packet sniffers and stateless firewalls do not. For example, a packet sniffer showing a TCP packet with source port 1080 and destination port 1494 might be either the SOCKetS or Citrix Independent Computing Architecture (ICA) protocols. The only way to know for sure is to examine the initial TCP handshake.

With UDP, client port selection depends on the application and may be incremental, fixed to a nonsensical value, or fixed equal to the server port.
