I'm seeing the parse error just fine. https://3v4l.org/NSaTZ
Are you catching the exception? Are you making sure to check for previous exceptions? https://3v4l.org/DXGtj

Description:
------------
Attempting to autoload a class file with a syntax error causes PHP to attempt to use the next
autoloader rather than throwing the syntax error.
Test script:
---------------
// Use built in autoloader for 99% of loads
spl_autoload_register();
// If that fails, see if it's a rare special case
spl_autoload_register('AutoLoadFallback');
function AutoLoadFallback($ClassName){
// ... try stuff...
throw new Exception('Could not autoload the class definition for
"'.$ClassName.'"');
}
// Try to load a new widget object
$oWidget = new Widget();
Expected result:
----------------
In this case, assume that the Widget object has a file that the default autoloader can find, but the
file contains a syntax error.
The expected result would be a syntax error thrown for the faulty file.
But what actually happens is, when an autoload file is found by the default autoload but a syntax
error exists in it, PHP calls the next autoloader in the chain AutoLoadFallback, which of course
throws an exception because it only handles cases that the default autoloader can't.
The result is getting an exception thrown by the AutoLoadFallback function, rather than a parse
error being thrown when the default autoloader tries to load the class. This blocks me from seeing
the real error and line number.
If I comment out the spl_autoload_register('AutoLoadFallback'); line, it throws a parse
error per normal.
