PECL: PHP Extension Community Library

Official website: pecl.php.net

Generally, php is installed in the bin directory, such as/usr/local/php/bin.

So if you want to use it directly, either add the bin directory to the environment variable PATH, or soft chain it to the/usr/bin directory.

Yum install php-devel

# Ubuntu/Debian is like this (php-pear contains pecl, php5-dev contains phpize, pecl depends on phpize) apt-get install php-pear php5-devpecl install swoole # CentOS/Redhat should be like this yum install php-pear php-develpecl install swoole # if it is self-compiled PHP (assuming the installation directory is /opt/php/7.0) /opt/php/7.0/bin/phpize/opt/php/7.0/bin/pecl
