OpenSwoole Hook Sleep

Since OpenSwoole v4.10.0 the data type of $seconds is fixed inline with PHP

The SWOOLE_HOOK_SLEEP flag will enable coroutine support for blocking sleep PHP functions. Support was added in OpenSwoole v4.2.0.

This includes support for:

• sleep
• usleep
• time_nanosleep
• time_sleep_until

Example

<?php

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

Co\run(function()
{
    go(function()
    {
        sleep(1);
        echo '1' . PHP_EOL;
    });

    go(function()
    {
        echo '2' . PHP_EOL;
    });
});
