Add extension library for PHP in Linux-php Tutorial

Example of adding an extension library for PHP in Linux: adding an extension library for mbstring

1. go to the PHP source code directory (if there is no source code, run the command: # php-v to view the version number, and then download the source code from the PHP official website)

2. go to the FTP Extension Library Directory under PHPi source code:

# Cd [Your PHP Source Folder]/ext/mbstring

3. use the phpize command to generate the configuration file:

# Phpize

4. execute configure:

#./Configure -- with-php-config =/usr/local/php/bin/php-config (the following path corresponds to the php-config directory on the local machine)

5. if no error is reported, run make:

# Make

6. after make is successful, the generated extension library file is in the modules subdirectory of the current directory. In this exampleMbstring. so, Copy this file to "/usr/local/php/lib/php/extensions/no-debug-non-zts-20121212/" (corresponding to the PHP Directory of the local machine)

7. modify/etc/php. ini, add a line under [mbstring]: extension = mbstring. so, and save
