HomeBackend DevelopmentPHP TutorialSeveral examples of eAccelerator accelerating PHP code

1, eaccelerator_put($key, $value, $ttl=0) Store $value into the cache with $key as the key name (object type is supported under php4, but it seems that it is not supported in zend2 from the source code). $ttl is the life cycle of this cache, in seconds. Omit this parameter or specify it as 0 Indicates no time limit until the server is restarted and cleared.

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

3, eaccelerator_rm($key) Remove cache based on $key

4, eaccelerator_gc() Remove and clean up all expired keys

5, eaccelerator_lock($key) Add a lock operation to $key to ensure data synchronization during multi-process and multi-thread operations. You need to call eaccelerator_unlock($key) to release this lock or wait for the program request to automatically release this lock. For example:

  1. eaccelerator_lock("count");
  2. eaccelerator_put("count",eaccelerator_get("count")+1));
  3. ?>
Copy code

6, eaccelerator_unlock($key) Release lock based on $key

7, eaccelerator_cache_output($key, $eval_code, $ttl=0) Cache the output of the $eval_code code for $ttl seconds (the $ttl parameter is the same as eacclerator_put) example:

Copy code

8, eaccelerator_cache_result($key, $ eval_code, $ttl=0) Cache the execution result of the $eval_code code for $ttl seconds, (the $ttl parameter is the same as eacclerator_put), similar to cache_output example:

Copy code

9, eaccelerator_cache_page($key, $ttl =0) Cache the current full page for $ttl seconds. example:

  1. eaccelerator_cache_page($_SERVER['PHP_SELF'].'?GET='.serialize($_GET),30);
  2. echo time();
  3. phpinfo();
  4. ?> ;
Copy code

10, eaccelerator_rm_page($key) Delete the cache executed by eaccelerator_cache_page(), also parameterized by $key.

Explain how load balancing affects session management and how to address it.Explain how load balancing affects session management and how to address it.Apr 29, 2025 am 12:42 AM

Load balancing affects session management, but can be resolved with session replication, session stickiness, and centralized session storage. 1. Session Replication Copy session data between servers. 2. Session stickiness directs user requests to the same server. 3. Centralized session storage uses independent servers such as Redis to store session data to ensure data sharing.

Are there any alternatives to PHP sessions?Are there any alternatives to PHP sessions?Apr 29, 2025 am 12:36 AM

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
