PHP Accelerator eaccelerator Configuration Usage Guide

#tar-ZXVF./eaccelerator-0.9.5-beta2.tar.bz2 #cd Eaccelerator-0.9.5-beta2 #export php_prefix= "/usr/local" (Import the PHP installation directory into the environment variable, freebsd default is/usr/local) # $PHP _prefix/bin/phpize #./configure--enable-eaccelerator=shared--with-php-config= $PHP _prefix/bin/php-config #make #make Install Copy Code 4, INI file configuration installation is complete, the following start to configure the php.ini file, Eaccelerator provides two ways to configure and call, respectively, as follows. Install as Zend extension mode: #mkdir/tmp/eaccelerator #chmod 777/tmp/eaccelerator Copy Code 5, verify the installation results through the browser to access your phpinfo () page or run php-i to get the PHP configuration information, if you see a message similar to the following indicates that the installation was successful. This program makes use of the Zend Scripting Language engine:zend Engine v2.1.0, Copyright (c) 1998-2006 Zend Technologies With Eaccelerator V0.9.5-beta2, Copyright (c) 2004-2006 eaccelerator, by Eaccelerator I have also installed Zend on my machine Optimizer3.0.1, so see the following information: This program makes use of the Zend Scripting Language engine:zend Engine v2.1.0, Copyright (c) 19 98-2006 Zend Technologies with Eaccelerator v0.9.5-beta2, Copyright (c) 2004-2006 eaccelerator, by Eaccelerator with Zend Extension Manager v1.0.10, Copyright (c) 2003-2006, by Zend Technologies with Zend Optimizer v3.0.1, Copyright (c) 1998-20 , by Zend Technologies if you turn on the debug option for Eaccelerator, you can see information like the following from the log Eaccelerator_lock ("Count"); Eaccelerator_put ("Count", Eaccelerator_get ("Count") +1)); ?> Copy Code Eaccelerator_unlock ($key) Release lock according to $key Eaccelerator_cache_output ($key, $eval _code, $ttl =0) will $eval the output cache of the _code code $ttl seconds, ($ttl parameters with Eacclerator_put) such as: Copy Code Eaccelerator_cache_result ($key, $eval _code, $ttl =0) caches the execution results of the $eval _code code $ttl seconds, ($ttl parameter is the same as Eacclerator_put), similar to cache_ Output for example: Copy Code Eaccelerator_cache_page ($key, $ttl =0) caches the current full page $ttl seconds. For example: Eaccelerator_cache_page ($_server[' php_self '). Get= '. Serialize ($_get), 30); echo Time (); Phpinfo (); ?> Copy Code Eaccelerator_rm_page ($key) deletes the cache executed by Eaccelerator_cache_page (), and the parameters are also $key 2, PHP code using eaccelerator accelerated test eaccelerator Powerful: (This code may not be valid in CLI mode) Class Test_cache { var $pro = ' Hello '; function Test_cache () { echo "Object created! \ n "; } function func () { Echo ', the world! '; } function Now ($t) { echo Date (' y-m-d h:i:s ', $t); } } $tt = Eaccelerator_get ("Test_tt"); if (! $tt) { $tt = new Test_cache; Eaccelerator_put ("Test_tt", $TT); echo "No cached! \ n "; } else { echo "Cached \ n "; } Echo $tt->pro; $tt->func (); $tt->now (Time () + 86400); ?> Copy Code In addition, it is said that the support for Eaccelerator has been integrated in the famous vbulletin 3.60Beta version.
