OpenSwoole Hook Blocking Function

The SWOOLE_HOOK_BLOCKING_FUNCTION flag will enable coroutine support for blocking PHP functions. Support was added in OpenSwoole v4.4.0.

This includes support for:

• gethostbyname
• exec
• shell_exec

Example

<?php

Co::set(['hook_flags' => SWOOLE_HOOK_BLOCKING_FUNCTION]);

Co\run(function()
{
    echo shell_exec('ls');
});
