In order to display a parse error, instead of setting display_errors in php.ini you can use a trick: use include.

Here are three pieces of code:

File: tst1.php

<?php
error_reporting(E_ALL);
ini_set('display_errors', 'On');
// Missing " and ;
echo "Testing

When running this file directly, it will show nothing, given display_errors is set to 0 in php.ini.

Now, try this:

File: tst2.php

<?php
error_reporting(E_ALL);
ini_set('display_errors', 'On');
include ("tst3.php");

File: tst3.php

<?php
// Missing " and ;
echo "Testing

Now run tst2.php which sets the error reporting, and then include tst3. You will see:

Parse error: syntax error, unexpected end of file, expecting variable (T_VARIABLE) or ${ (T_DOLLAR_OPEN_CURLY_BRACES) or {$ (T_CURLY_OPEN) in tst3.php on line 4
