This article will explain in detail how PHP uses eAccelerator's API development. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

1. API and documentation:

EAccelerator provides a convenient and stable native cache implementation. Because most of the code implementations are based on shared memory, they can only be used in * nix platform. Windows platform Michael does not know when it will be supported in this respect.

EAccelerator provides the following API interfaces and files: (the following files are all in the doc/php/ directory of the source package)

File list:

The copy code is as follows:

Cache.php

Dasm.php

Encoder.php

Info.php

Loader.php

Session.php

Shared_memory.php

Interface list:

The copy 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 translated APIs:

The copy code is as follows:

Eaccelerator_put ($key, $value, $ttl=0)

Store $value in the cache with the key name of $key (object types are supported in php4. It seems that the source code does not support it in zend2). $ttl is the lifetime of the cache (in seconds). Omitting this parameter or specifying 0 means unlimited time until the server is rebooted and emptied.

Eaccelerator_get ($key)

According to $key, the data stored in the corresponding eaccelerator_put () is returned from the cache. If the cache has expired or does not exist, the return value is NULL.

Eaccelerator_rm ($key)

Remove the cache according to $key

Eaccelerator_gc ()

Remove and clean up all expired key

Eaccelerator_lock ($key)

Add a lock operation to $key to ensure data synchronization during multiprocess and multithreaded operations. You need to call eaccelerator_unlock ($key) to release the lock or wait for the lock to be released automatically when the program request ends.

For example:

Eaccelerator_cache_page ($key, $ttl=0)

Caches the current full page for $ttl seconds.

For example:

Eaccelerator_rm_page ($key)

Delete the cache executed by eaccelerator_cache_page (), and the parameter is also $key

2. Use eAccelerator acceleration in PHP code

In addition, eAccelerator support has been integrated into PHPCMS. Here is a piece of code from PHPCMS.

The copy 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 ()

}

}
