Installation _php tutorials for PHP and its modules

Installation of PHP and its modules

We know that ASP operation requires PWS or IIS server support, without these two servers, it can not run. ASP server-supported installations typically include ASP

The language interpreter and the WEB server.

In the same way, the installation of PHP is divided into two parts: one for the installation of PHP and its modules, and two for the Web server. Installation of PHP and its modules, including the installation of PHP core files,

Installation of the relevant extension modules and PHP. INI file is set for various options.

PHP If there is no Web server, it does not play much role, so you must install a Web server, and make the necessary configuration, so that the Web server can handle the PHP foot

This.

Now that most of our operating systems are Microsoft Windows, let's start with the installation of the PHP runtime environment and the WEB server under the Windows operating platform.

First, the installation of PHP and its modules

PHP installation is relatively simple. First of all we want to download from the http://www.php.net/site to adapt to their own platform PHP compression package (the compression package used in the example is php-4.1.2.tar.gz), unzip them, and then click Install, usually we install it into the C:\PHP directory ( This is determined by the personal operating system drive letter).

For all the plug-in modules required to have a corresponding dynamic link library. If the module file you installed is not included in PHP, you can find and download it to the http://www.php.net/website and then copy it to the C:\PHP directory. This completes the installation.

The next step is to focus on the time, for the first contact with PHP, beginning to learn PHP, this step is very important, because if not set correctly, will not be able to interpret any PHP script, that is, you need PHP basic operating conditions are not set up.

Next we want to php.ini with the PHP configuration file. Copy the text configuration file from the installation directory of PHP php.ini-dist to your Windows directory (c:\windows or C:\Winnt). and change the file suffix name to php.ini. Here's a fairly important question to note, If you have a php.ini file in both the Windows directory and the PHP directory, the files in the PHP directory are preferred and high, that is, the PHP interpreter will use the PHP directory as a PHP configuration file, the Windows directory will not work.

Attentive friends will notice that the PHP directory also has a php.ini-optimized file, and phin.ini-dist is also the PHP interpreter configuration file, the configuration of the two similar, but the former in some of the options are optimized in order to reduce the use of system memory. However, it is recommended that you do not know PHP very familiar with a friend do not use this file, because it is php3 when it is retained, for PHP4 may cause some modules function failure.

On the network, there are quite a lot of files in the configuration of php.ini files, but there are a lot of misunderstanding, the following part of the misunderstanding content:
