HomeBackend DevelopmentPHP Tutorial网站加速PHP缓冲的免费实现方法_PHP

我们知道 Zend 有免费的优化引擎针对 PHP 而作,但是 FreeLAMP 这次采用的是一个叫做 PHP Accelerator 的缓冲产品。
  我们在 “LAMP 加速” 这篇文章中阐述过加速的几种办法,其中提到了 PHP Accelerator,它的安装方法十分简单,但是需要去他的网站获取一个激活键。


  一、下载:

  www.php-accelerator.co.uk/download.php

  二、获取激活键并安装:

  www.php-accelerator.co.uk/activate.php

  注册自己的 SERVER_NAME 后,你会得到下面的提示:

  Your key for www.freelamp.com is 8edfd13946c96309244fcca309415902

  Now you must set the key for www.freelamp.com in your site configuration.

  For single domains not using virtual hosts

  The key can be set in the php.ini file as follows:

  # PHPA key for www.freelamp.com

  #

  phpa.registration_key = 8edfd13946c96309244fcca309415902

  For domains setup as a virtual host

  Add the key to the domain specific section for your web server.

  # www.freelamp.com VHost entry

  #

  

  ServerName www.freelamp.com

  # ... (other vhost specific config)

  # php settings

  php_value phpa.registration_key 8edfd13946c96309244fcca309415902

  # also enable phpa if set to off in the php.ini (the default is on)

  php_value phpa 1

  

  具体的 phpa 值的设置,可以参考软件随带的 CONFIGURATION 文件的配置。

  由于大多数网站是虚拟主机配置,所以,建议采用 php_value phpa. 的方式设置。

  例如:

  php_value phpa.tweaks off

  php_value phpa.cache_dir /tmp

  php_value phpa.file_perms 400

  php_value phpa.ignore_files "/index.php, /a/test.php"

  # php_value phpa.ignore_dirs "/data/WWW/site1/,/cache/"

  php_value phpa.shm_size 8

  php_value phpa.shm_key 0xc0deb00

  php_value phpa.shm_perms 664

  三、设置 php.ini

  假设我们把下载后的文件解开到 /usr/local/php ,那么在 php.ini 中加入:

  zend_extension=/usr/local/php/php_accelerator_1.2p2.so

  并注释掉原来的 Zend 优化引擎:

  # zend_extension=/usr/local/Zend/lib/ZendOptimizer.so

  重新启动 Apache ,用浏览器浏览一个任意 PHP 页面可以看到 /tmp 下面生成了一些 phpa 开头的文件。另外一个检查缓冲是否起作用的办法是看 phpinfo() 的输出,原来的 Zend 优化引擎的说明部分,已经被显示成:

  This program makes use of the Zend Scripting Language Engine:

  Zend Engine v1.1.1, Copyright (c) 1998-2001 Zend Technologies

  with the PHP Accelerator v1.2p2, Copyright (c) 2001-2002, by Nick Lindridge

  需要说明的是,安装 INSTALL 安装说明上的办法,其中的 .so 文件和真实的 .so 文件有差异,所以,你在安装的时候需要注意到这个区别。

  四、调整缓冲大小

  PHP Accelerator 提供了缓冲管理命令:

  phpa_cache_admin -mv 观察内存的缓冲情况

  phpa_cache_admin -fv 观察文件的缓冲情况

  phpa_cache_admin -k 设置缓冲大小

  五、总结

  该软件提供的 INSTALL 文件阐述了关于性能上的一些说法,笔者不在这里赘述。

  需要说明的是,FreeLAMP.com 的文章目前不是 PHP 架构的,但是论坛系统是 PHP 架构的,所以性能上的提升只会是论坛系统的提升。

How does PHP type hinting work, including scalar types, return types, union types, and nullable types?How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AM

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values ​​and handle functions that may return null values.

How does PHP handle object cloning (clone keyword) and the __clone magic method?How does PHP handle object cloning (clone keyword) and the __clone magic method?Apr 17, 2025 am 12:24 AM

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

PHP vs. Python: Use Cases and ApplicationsPHP vs. Python: Use Cases and ApplicationsApr 17, 2025 am 12:23 AM

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.

Describe different HTTP caching headers (e.g., Cache-Control, ETag, Last-Modified).Describe different HTTP caching headers (e.g., Cache-Control, ETag, Last-Modified).Apr 17, 2025 am 12:22 AM

Key players in HTTP cache headers include Cache-Control, ETag, and Last-Modified. 1.Cache-Control is used to control caching policies. Example: Cache-Control:max-age=3600,public. 2. ETag verifies resource changes through unique identifiers, example: ETag: "686897696a7c876b7e". 3.Last-Modified indicates the resource's last modification time, example: Last-Modified:Wed,21Oct201507:28:00GMT.

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1?Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1?Apr 17, 2025 am 12:06 AM

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values ​​to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
