PHP Unlink Not working

Question

I am trying to delete photo in php using unlink. I have used it earlier on other server but this time it is not working. I have used absolute path for a test but still does

Answer 1

use filesystem path,
first define path like this:

define("WEB_ROOT",substr(dirname(__FILE__),0,strlen(dirname(__FILE__))-3));

and check file is exist or not,if exist then unlink the file.

$filename=WEB_ROOT."img1.jpg";
if(file_exists($filename))
{
$img=unlink(WEB_ROOT."img1.jpg");
}
