$newname =   substr($name, 0, -4); //removing.jpg
// Real name
$rev= strrev("$newname"); // outputs "0801x0291-noen-sthgil-srac"
$revok= strstr($rev, '-'); //outputs "-noen-sthgil-srac"
$neutral = strrev("$revok"); //outputs "cars-lights-neon-"
$neutral = substr($neutral, 0, -1); //outputs "cars-lights-neon"

$filename = $neutral.".jpg"; //outputs "cars-lights-neon.jpg";

You can use preg_replace :

$string = 'cars-lights-neon-1920x1080.jpg';
$filename = preg_replace('/-[0-9]{3,4}x[0-9]{3,4}/', '', $string);
