Have you enabled the option which allows you to use external URLs? You can set it in php.ini:

allow_url_fopen = 1

Answer 2

file_exists() needs to use a file path on the hard drive, not a URL. So you should have something more like:

$thumb_name = $_SERVER['DOCUMENT_ROOT'] . 'images/userphoto/1/2/2/59874a886a0356abc1_thumb9.jpg';
if(file_exists($thumb_name)) {
    some_code
}

Answer 3

Try Below one. Its working for me

define('SITE_PATH2', 'http://localhost/');
$noimg = SITE_PATH2. 'images/userphoto/noimagesmall.jpg';
$thumb_name = 'http://localhost/images/userphoto/1/2/2/59874a886a0356abc1_thumb9.jpg';

if ($fileopen = @fopen($thumb_name)) {
    $img_name = $thumb_name;
    fclose($fileopen);
}else{
    $img_name = $noimg;
}
echo $img_name;

docs say:

As of PHP 5.0.0, this function can also be used with some URL wrappers. Refer to List of Supported Protocols/Wrappers for a listing of which wrappers support stat() family of functionality.
