Swoole Hook File

Notice: the documentation is suitable for PHP extension swoole until v4.7.1, we only support PHP extension openswoole from v4.7.1

The SWOOLE_HOOK_FILE flag will enable coroutine support for native PHP file operation functions. Support was added in v4.3.0.

This includes support for:

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



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

    $fp = fopen("test.log", "a+");
    fwrite($fp, str_repeat('A', 2048));
    fwrite($fp, str_repeat('B', 2048));
