Detailed tutorial on the installation method of PHP's swoole extension, phpswoole installation method

Swoole supports PHP 5.3.10 or above, so please install PHP 5.3.10 or above before installing Swoole. Now let’s introduce the installation and configuration method of PHP under Windows.

Software version: php-5.3.1-Win32-VC6-x86.zip

This does not require additional installation of .net libraries, so this is used. Others can be used.

1.PHP installation

Use the green method to download the Zip file and extract it.

2. Configuration

In the root directory of the decompression, find php.ini-development, which is a configuration file for the development environment; there is also a php.ini-production, which is a configuration file for the production environment. Using php.in-development, make a copy and rename it to php.ini. Start editing.

Location registe_globals =Off;

It is recommended not to open it. The difference is that this value is used to open global variables, such as the value sent from the form. If this value is set to "Off", you can only use "$_POST['variable name'], $ _GET['variable name']" and so on to get the sent value. If it is set to "On", you can directly use "$variable name" to get the sent value. Of course, it is safer to set it to "Off". No one can easily intercept the data transmitted between web pages. Whether this value is changed to "On" depends on your own feeling. Is safety or convenience more important?

In order to enable php to call other modules, you can search with the extension keyword and locate as follows. Remove the semicolon before the option to open support for this module.

The more modules loaded, it will occupy slightly more resources, which can be ignored. For example, to enable mysql support, find the following

;extension=php_mysql.dll

Just remove the ";" comment in front.

All modules are placed in the ext directory under the PHP decompression directory and can be enabled as needed.

Error when loading module:

Sometimes when starting Apache, the error "The specified module cannot be found" will be prompted. This is because the location of these module files is not specified. Locate the keyword "extension_dir" and modify the directory for your PHP module under Windows.

For example, if my PHP directory is in D:PHP, then configure

exession_dir = "D:PHPext"

This way there will be no error when starting Apache.

Here is the simplest method to directly specify the PHP installation path and the ext path inside it to the Windows system path - right-click on "My Computer", "Properties", select the "Advanced" tab, and click Select "Environment Variables", find the "Path" variable under "System Variables", select it, double-click or click "Edit", and add ";D:php;D:phpext" to the end of the original value. Of course, the "D:php" is my installation directory. You need to change it to your own php installation directory, as shown in the figure below, confirm everything.

3. Work with Apache

php is combined with Apache in module mode, open Apache's configuration file, locate it with the keyword "LoadModule", and configure the module to be loaded,

Add the following two lines at the end:

LoadModule php5_module D:/php/php5apache2_2.dll

PHPIniDir "D:/php"

The first line "LoadModule php5_module D:/php/php5apache2_2.dll" refers to loading PHP in module mode, and the second line "PHPIniDir "D:/php"" indicates the location of PHP's configuration file php.ini. Of course, "D:/php" needs to be changed to the directory where php is decompressed that you selected previously.

There are both php5apache2.dll and php5apache2_2.dll in the php decompression directory. Because our apache version is 2.2, the dll is loaded

Use php5apache2_2.dll and configure it according to your own situation.

Search with the keyword AddType application to define the file type that can execute php,

The original text is as follows: AddType allows you to add to or override the MIME configuration
# file specified in TypesConfig for specific file types.

Join

AddType application/x-httpd-php .php

AddTypeapplication/x-httpd-php.html

Two lines, you can also add more. The essence is to add file types that can execute php. For example, if you add a line "AddTypeapplication/x-httpd-php .htm", then the .htm file can also execute php programs. , you can even add the previous line "AddTypeapplication/x-httpd-php .txt" so that ordinary text txt can also run php programs.

The basic configuration of PHP is completed.

Continue to introduce the PHP swoole extension installation method:

After the installation is complete, put php into the environment variable

# export PATH=/usr/local/php/bin:$PATH 
# export PATH=/usr/local/php/sbin:$PATH

After saving, enter the command in the terminal:

# source ~/.bashrc

然后即可安装swoole扩展。 请到swoole扩展下载地址下载最新stable版本, 本文以1.8.5为例：

# wget https://github.com/swoole/swoole-src/archive/swoole-1.8.5-stable.tar.gz
# tar zxvf swoole-1.8.5-stable.tar.gz
# cd swoole-1.8.5-stable
# phpize 
# ./configure 
# make && make install

然后在php.ini文件添加Swoole扩展：

extension=swoole.so

重启php-fpm:

# service php-fpm restart

然后查看扩展安装情况。如果在列出的扩展中看到了swoole，则说明安装成功：

php -m

以上就是本文的全部内容，希望对大家学习php程序设计有所帮助。
