You can use below method to crop image,

/*parameters are 
    $image =source image name
    $width = target width
    $height = height of image
    $scale = scale of image*/
    function resizeImage($image,$width,$height,$scale) {
        //generate new image height and width of source image
        $newImageWidth = ceil($width * $scale);
        $newImageHeight = ceil($height * $scale);
        //Create a new true color image
        $newImage = imagecreatetruecolor($newImageWidth,$newImageHeight);
        //Create a new image from file 
        $source = imagecreatefromjpeg($image);
        //Copy and resize part of an image with resampling
        imagecopyresampled($newImage,$source,0,0,0,0,$newImageWidth,$newImageHeight,$width,$height);
        //Output image to file
        imagejpeg($newImage,$image,90);
        //set rights on image file
        chmod($image, 0777);
        //return crop image
        return $image;
    }
