The Grid Search

    Here my solution

    function gridSearch($G, $P) {
    // Write your code here
    $xG = count($G);
    $yG = strlen($G[0]);
    $xP = count($P);
    $yP = strlen($P[0]);
    
    for($x=0; $x<=$xG-$xP; $x++) {
        for ($y=0; $y<=$yG-$yP; $y++) {
            $matchLines = 0;
            for($i=0; $i<$xP; $i++) {
                if(substr($G[$i+$x], $y, $yP) !== $P[$i]) break;
                $matchLines++;
            }
            
            if($matchLines === $xP) return "YES";
        }
    }
    
    return "NO";
}
