Installation method and detailed tutorial of swoole extension in PHP

This article mainly shares with you the swoole extension installation method and detailed tutorial in PHP. It is practical and of reference value. Interested friends can refer to it

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

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

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

1.PHP installation

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

2. Configuration

Find php.ini-development in the root directory of the decompression, which is the configuration file used for the development environment; also There is a php.ini-production, this is the 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 by the form. If If this value is set to "Off", you can only use "$_POST['variable name'], $_GET['variable name']", etc. to get the sent value. If it is set to "On", you can use it directly. "$Variable name" to get the value sent. Of course, setting it to "Off" is safer and will not allow people to 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

and 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 because these module files are not specified. Location, 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, configure

exession_dir = "D:\PHP\ext"

In this way, no error will be reported 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", and select "Advanced" tab, click "Environment Variables", find the "Path" variable under "System Variables", select it, double-click or click "Edit", and add ";D:\php;D:\php\ext" to the original value At the end, of course, "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 together with Apache

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

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. The second line "PHPIniDir "D:/php"" indicates the location of PHP's configuration file php.ini. Of course , where "D:/php" should 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, so load the dll

Use php5apache2_2.dll according to your own situation configuration.

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. html

two lines, you can also add more, the essence is to add a file type that can execute php, for example, if you add a line "AddTypeapplication/x-httpd-php .htm", then the .htm file will also The php program can be executed. You can even add the previous line "AddTypeapplication/x-httpd-php .txt" so that ordinary text txt can also run the php program.
