OpenSwoole Hook File

The OpenSwoole\Runtime::HOOK_FILE flag will enable coroutine support for native PHP file operation functions. Support was added in OpenSwoole v4.3.0.

This includes support for:

• fopen
• fread and fgets
• fwrite and fputs
• file_get_contents and file_put_contents
• unlink
• mkdir
• rmdir

Example

<?php

Co::set(['hook_flags' => OpenSwoole\Runtime::HOOK_FILE]);

Co::run(function()
{
    $fp = fopen("test.log", "a+");
    fwrite($fp, str_repeat('A', 2048));
    fwrite($fp, str_repeat('B', 2048));
});
