Today I was working on a site, where I  had to set a no-image placeholder on the places where images are not present, that means I need to check images are present or not, its a very simple job, but what I found was image url’s are coming from database and they all are broken links.

So now my job is to write a code which will check the images links are broken or not if broken then place a no-image place holder else image url. Here is the example on how I checked broken image url’s:

function check_url($url)
{
	$ch = curl_init();
	curl_setopt($ch, CURLOPT_URL, $url);
	curl_setopt($ch, CURLOPT_HEADER, 1);
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
	$data = curl_exec($ch);
	$headers = curl_getinfo($ch);
	curl_close($ch);
	return $headers['http_code'];
}
$myurl = "http://www.flickr.com/photos/thecancerus/2869110105/";
$satus = check_url($myurl);
if($satus == '200')
	echo "Its works";
else
	echo "broken url";

Hope it helps!!!
