Check if remote image exists

:shrug: :shrug:

Please help before this script drives me insane.

It tries to download a skin from Minecraft.

 

It works fine, except, if it returns an error code, (301, 302, 404), don't download, and using my image (char.png) as a replacement.

I can get the error code, except, no matter how I compare it, it will a) still say it's 302 or b) not work at all.

 

 

Here's my code:

 

userskin.inc.php >

<?php
require('class.mineuser.php');
if(!isset($_GET['width']) || strlen(trim($_GET['width'])) == 0 || !isset($_GET['height']) || strlen(trim($_GET['height'])) == 0) {
$x = 16;
$y = 16;
} else {
$x = $_GET['width'];
$y = $_GET['height'];
}

if(isset($_GET['refresh'])) 
$refresh = true;
else
$refresh = false;

if(isset($_GET['debug'])) 
$debug = true;
else
$debug = false;

$http = curl_init("http://www.minecraft.net/skin/{$_GET['user']}.png");
curl_setopt($http, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($http);
$http_status = curl_getinfo($http, CURLINFO_HTTP_CODE);
$resp = preg_match("/302/", $http_status, $match);
$code = $match[0];
if($code == 302) {
mineuser::downloadSkin($_GET['user'], $_GET['path'], $code, $refresh);
mineuser::getFace($_GET['user'].".png", $x, $y, $_GET['path'], $code, $debug);
} else {
mineuser::getFace("char.png", $x, $y, $_GET['path'], $code, $debug);
}

 

class.mineuser.php >

<?php
class mineuser {
	public static function downloadSkin($user, $path = "", $resp, $new = false) {
		if($resp !== 302) {
		//Checks if $new is true, if it is, then delete $user.png and download a new one.
		if($new == true) unlink("$path/$user.png");

		//Checks if the users skin already exists (faster loading time)
		if(!file_exists("$path/$user.png")) { 
			$fh = fopen("$path/$user.png", "w"); 
			$file = file("http://www.minecraft.net/skin/$user.png");

			foreach($file as $char) //Since it's an array, we use a foreach loop and write each character individually
				fwrite($fh, $char);

			fclose($fh); //Close our file handler. 
		}
		} else {

		}
	} //End of function downloadSkin()

	public static function getFace($user, $width, $height, $path, $resp, $debug = true) {
		$im = imagecreatetruecolor($width, $height);
		if($debug == false) {
		header("Content-type: image/png");
		}
		if($resp === 302) {
			$image = imagecreatefrompng("$path/char.png");
		} else {
			$image = imagecreatefrompng("$path/$user");
		}
		imagecopyresampled($im, $image, 0, 0, 8, 8, $width, $height, 8, ;

		imagepng($im);
		imagedestroy($im);

	} //End of function getFace()
}
?>
