title: Removing "child said into stdout/stderr" prefix from logs in GAE php74 standard environment
body: <p>I'm running a php74 standard environment in Google App Engine and outputting logs to <code>php://stdout</code>. Unfortunately, all the logs are prefixed with <code>child X said into stdout</code> and all the PHP errors are prefixed with <code>child X said into stderr</code>. Outside of GAE, I've addressed this by modifying the php-fpm runtime config to set <code>catch_workers_output = yes</code> but on the <strong>standard</strong> environment, you can't change the runtime config, you can only set <code>php.ini</code> changes.</p>
  <p>Is there a way to remove this prefix on the standard environment?</p>
