Right, as simple as this is supposed to be, I simply cannot get this code to work.
I am trying to check whether a users avatar image exists, and in case it does not, use the default one instead. Now, even though the image exists and filename, path, spelling, format, etc. are correct, file_exists() always returns false claiming that the file does not exist.
<?php
$avatar = 'http://'.$_SERVER['SERVER_NAME'].'/ihg/dist/img/user'.$_SESSION['ID'].'-128x128.jpg';
$default = 'http://'.$_SERVER['SERVER_NAME']."/ihg/dist/img/user_default.jpg";
if (!file_exists($avatar)) {
echo "<img src=\"$default\" class=\"user-image\" alt=\"User Image\">";
} else {
echo "<img src=\"$avatar\" class=\"user-image\" alt=\"User Image\">";
}
?>
Is this a server side issue or is the code faulty?
EDIT: I also tried using the $_SERVER['DOCUMENT_ROOT'] variable and absolute paths, but no result.
file_exists() accepts a file path rather than a URL.
To determine whether an image exists based on a URL you need to check the response type instead.
Since these are local resources you simply need to switch from using a URL to the full server file path. ($avatar = '/path/to/root/...)
