PHP 5.0 Pear installation method_PHP tutorial

Pear is a PHP extension and application library, which contains many useful classes. After installing php5.0, pear is not actually installed. The installation method is as follows:
1. Double-click go-pear in the php directory .bat.
2. Follow the prompts to enter some setting information. The main thing is to add the gateway of the LAN, such as http://192.168.0.1:80/. Pear needs to use this address to access the Internet. If there is no proxy server, just press Enter.
3. Then you will be prompted to bind some packages to PHP, select Y.
4. Then install the basic package and prompt that the installation is successful, it’s that simple.
5. Open the php.ini file in the windows directory, and then find the following location:
; UNIX: "/path1:/path2"
;include_path = ".:/php/includes"

; Windows: "path1;path2"
;include_path = ".;c:phpincludes"

Remove the comment on the last line, and then change the following path to your PEAR path. For example:
include_path = ".;c:phppear"
Save PHP.INI and then restart APACHE.
