This is due to the @ before the trigger_error function name.

TestErrorHandler.php

<?php

error_reporting(E_ALL);

set_error_handler(function ( int $errno , string $errstr , string $errfile , int $errline , array $errcontext) {
	var_dump(error_reporting(), ini_get('error_reporting'), error_reporting() & $errno, $errstr);
}, E_ALL);

@trigger_error('deprecated', E_USER_DEPRECATED);

@trigger_error('user warning', E_USER_NOTICE);

var_dump(PHP_VERSION);
