Php upload image and resize

1

I’m using the following script to upload a jpeg image to the server. The upload is working fine but the resize function is having trouble writing the resized image to the specified directory. that directory is 777 as well as its parent directory.

any ideas??

<?php
function resizeImage($source, $destination = NULL,$wdt, $height = NULL){
    if(empty($height)){
        // Height is nit set so we are keeping the same aspect ratio.
        list($width, $height) = getimagesize($source);
        if($width > $height){
            $w = $wdt;
            $h = ($height / $width) * $w;
            $w = $w;
        }else{
            $w = $wdt;
            $h = $w;
            $w = ($width / $height) * $w;
        }
    }else{
        // Both width and Height are set.
        // this will reshape to the new sizes.
        $w = $wdt;
        $h = $height;
    }
    $source_image = @file_get_contents($source) or die('Could not open'.$source);
    $source_image = @imagecreatefromstring($source_image) or die($source.' is not a valid image');
    $sw = imagesx($source_image);
    $sh = imagesy($source_image);
    $ar = $sw/$sh;
    $tar = $w/$h;
    if($ar >= $tar){
        $x1 = round(($sw - ($sw * ($tar/$ar)))/2);
        $x2 = round($sw * ($tar/$ar));
        $y1 = 0;
        $y2 = $sh;
    }else{
        $x1 = 0;
        $y1 = 0;
        $x2 = $sw;
        $y2 = round($sw/$tar);
    }
    $slate = @imagecreatetruecolor($w, $h) or die('Invalid thumbnail dimmensions');
    imagecopyresampled($slate, $source_image, 0, 0, $x1, $y1, $w, $h, $x2, $y2);
    // If $destination is not set this will output the raw image to the browser and not save the file
    if(!$destination) header('Content-type: image/jpeg');
    @imagejpeg($slate, $destination, 75) or die('Directory permission problem');
    ImageDestroy($slate);
    ImageDestroy($source_image);
    if(!$destination) exit;
    return true;
}

//handle uploaded file

$uploaddir = 'upload/';
$file = basename($_FILES['photo']['name']);

$uploadfile = $uploaddir . $file;

if (move_uploaded_file($_FILES['photo']['tmp_name'], $uploadfile)) {
    echo "YES";
	
	$source=$uploadfile;
	$wdt = 960;
	
	$destination="http://www.n8peg.com/grap/upload/resized/";
	
	resizeImage($source, $destination, $wdt, $height);
} else {
    echo "NO";
}
