1. API and Documentation Description:
Eaccelerator provides a convenient and stable native cache implementation, because most code implementations are based on shared memory and can only be used in the *nix platform, and the Windows platform Michael does not know when this is supported.
Eaccelerator provides the following API interface and files: (The following files are in the source package doc/php/directory)
file list:
Copy CodeThe code is as follows:
cache.php
dasm.php
encoder.php
info.php
loader.php
session.php
shared_memory.php
Interface list:
Copy CodeThe code is as follows:
Array eaccelerator_cached_scripts ()
void Eaccelerator_cache_output (String $key, String $eval _code, [int $ttl = 0])
void Eaccelerator_cache_page (String $key, [int $ttl = 0])
void Eaccelerator_cache_result (String $key, string $code, [int $ttl = 0])
void Eaccelerator_caching (Boolean $flag)
void Eaccelerator_clean ()
void Eaccelerator_clear ()
Array eaccelerator_dasm_file (mixed $filename)
Mixed Eaccelerator_encode (mixed $src, [mixed $prefix = '], [string $pre _content = '], [string $post _content = '])
void eaccelerator_gc ()
Mixed Eaccelerator_get (String $key)
Array Eaccelerator_info ()
Array Eaccelerator_list_keys ()
void Eaccelerator_load ()
Boolean Eaccelerator_lock (String $key)
void Eaccelerator_optimizer (Boolean $flag)
void Eaccelerator_purge ()
Boolean eaccelerator_put (String $key, mixed $value, [int $ttl = 0])
Array eaccelerator_removed_scripts ()
Boolean eaccelerator_rm (String $key)
void Eaccelerator_rm_page (String $key)
Boolean eaccelerator_set_session_handlers ()
Boolean Eaccelerator_unlock (String $key)
Here are some of the user interface after the translation of the description:
Copy CodeThe code is as follows:
Eaccelerator_put ($key, $value, $ttl =0)
The $value to the $key as the key name in the cache (PHP4 support for the type of image, see the source is not supported in the Zend2), $ttl is the life cycle of this cache, the unit is the second, omit the parameter or specify 0 for unlimited, until the server restarts to empty.
Eaccelerator_get ($key)
The return value is NULL if the cache has expired or is not present, based on $key returning the corresponding eaccelerator_put () data from the cache.
EACCELERATOR_RM ($key)
To remove a cache from a $key
EACCELERATOR_GC ()
Remove cleanup of all expired keys
Eaccelerator_lock ($key)
For $key plus locking operations to ensure data synchronization during multi-process multithreaded operations. You need to call Eaccelerator_unlock ($key) to release this lock or to automatically release this lock when the program request ends.
For example:
Eaccelerator_lock ("Count");
Eaccelerator_put ("Count", Eaccelerator_get ("Count") +1));
?>
Eaccelerator_unlock ($key)
Release the lock according to the $key
Eaccelerator_cache_output ($key, $eval _code, $ttl =0)
$eval the output cache of the _code code $ttl seconds ($ttl parameter same as Eacclerator_put)
For example:
Eaccelerator_cache_result ($key, $eval _code, $ttl =0)
Caches the execution results of the $eval _code code $ttl seconds ($ttl parameter with eacclerator_put), similar to Cache_output
For example:
Eaccelerator_cache_page ($key, $ttl =0)
Caches the current full page $ttl seconds.
For example:
Eaccelerator_cache_page ($_server[' php_self '). Get= '. Serialize ($_get), 30);
echo Time ();
Phpinfo ();
?>
Eaccelerator_rm_page ($key)
Deletes the cache executed by Eaccelerator_cache_page (), and the parameters are also $key
2. Use eaccelerator acceleration in PHP code
In addition, the support for Eaccelerator has been integrated into the PHPCMS, and the following is a code from PHPCMS
Copy CodeThe code is as follows:
Class Cache
{
function __construct ()
{
}
function Cache ()
{
$this->__construct ();
}
function Get ($name)
{
Return Eaccelerator_get ($name);
}
function set ($name, $value, $ttl = 0)
{
Eaccelerator_lock ($name);
Return Eaccelerator_put ($name, $value, $ttl);
}
function rm ($name)
{
Return Eaccelerator_rm ($name);
}
function Clear ()
{
return eaccelerator_gc ();
}
}
