PHP Add extension

There are a lot of ways to install extensions to PHP

First, recompile

Enter the PHP source directory./configure--prefix=/usr/local/php ... [Other compilation parameters]

Ii. adding extensions via Phpize

Enter the PHP source extension application directory ext, for example:

/usr/local/src/ezhttp-master/soft/php-5.3.27/ext/pcntl/

Execute the phpize command in the Pcntl directory and then in configure, run the following result:

Finally, modify the php.ini configuration file, add it on the last line, and then restart Apache

Extension=pcntl.so

Third, some extensions can be added via the pecl command

For example, install the libevent extension Direct input command pecl install libevent in the directory

/usr/local/php/lib/php/extensions/no-debug-zts-20090626/

Under Generate libevent.so, and finally modify the configuration file PHP.ini (same previous method)
