Using Regx:

<?php
$a = [
    'C:\wamp\www\sthub\application\controllers/../../download/qr/SyR04A-94527.jpg',
    'C:\wamp\www\sthub\application\controllers/../../download/qr/SyR05A-95528.jpg'
];

foreach( $a AS $path ){
    if( preg_match('/\/([^\/]+)\.[a-z]+$/i', $path, $match))
        print_r($match[1]."
");
}

Outputs:

 SyR04A-94527
 SyR05A-95528

You can test it here http://sandbox.onlinephpfunctions.com/code/081543329dda8b9e0ef59836995184171ff4ce66

I was going to use pathinfo but my sandbox site has it disabled, and I'm to lazy to turn my server on. But it would be something like this:

$a = [
   'C:\wamp\www\sthub\application\controllers/../../download/qr/SyR04A-94527.jpg',
   'C:\wamp\www\sthub\application\controllers/../../download/qr/SyR05A-95528.jpg'
];

foreach( $a AS $path )
    echo pathinfo ($path, PATHINFO_FILENAME)."
";

Cheers!
