PHP file_exists else

Question

When I use to following PHP code;

<?php if (file_exists("/foto/Maurice.jpg"))
{
echo "<center><img src='/foto/Maurice.jpg'/></center>";
}
else {
echo "<center><img src='/afbeeldingen/kaars1.png'/></center>"; 
?>

My browser always shows kaars1.png instead of Maurice.jpg I also tried !file_exists but then it doesn't show kaars1.png, when Maurice.jpg doesn't exist. Is there a simpel way to fix this?

`file_exists` is *only* for files on your server's (local) filesystem. — gen_Eric, Jan 22 '16 at 23:16

give the full url in `file_exist`.(full path where your images exist) — Alive to die - Anant, Jan 22 '16 at 23:21
Just for the sake of asking, are you sure the file actually exists and is accessible by php? — Joseph Young, Jan 22 '16 at 23:21
Then use `if (file_exists($_SERVER['DOCUMENT_ROOT'] . 'foto/Maurice.jpg')) { ... }` — r3mainer, Jan 22 '16 at 23:44

file_exists is only for files on your server's (local) filesystem. You need to actually try to request the URL and see if it exists or not.

You can use cURL to do this.

$handle = curl_init('https://picathartes.com/foto/Maurice.jpg');
curl_setopt($handle,  CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($handle, CURLOPT_NOBODY, TRUE);
$response = curl_exec($handle);

// Check for 404 (file not found).
$httpCode = curl_getinfo($handle, CURLINFO_HTTP_CODE);
if($httpCode == 404) {
    echo "<center><img src='https://picathartes.com/afbeeldingen/kaars1.png'/></center>"; 
}   
else{
    echo "<center><img src='https://picathartes.com/foto/Maurice.jpg'/></center>";
} 
curl_close($handle);

It might work better to not include the actual body of the response (curl_setopt($handle, CURLOPT_NOBODY, 1) – georaldc Jan 22 '16 at 23:21
@georaldc: Possibly. I mostly just "borrowed" the code from another question. Just getting the header without the body seems like a good idea. – gen_Eric Jan 22 '16 at 23:29
Its a nice answer, but what makes you think that the file being looked for is on another server? – RiggsFolly Jan 22 '16 at 23:34

@RiggsFolly The OP changed the question: http://stackoverflow.com/posts/34957526/revisions – r3mainer Jan 22 '16 at 23:44

This is an answer to your second question

The correct solution depends upon your actual directory structure and the location of the script file in relation to the actual folder and file you are looking for, but to start finding a solution the / in "/foto/Maurice.jpg" say go back to the root directory and look for a directory called /foto

So if this folder is under your DocumentRoot try using

if (file_exists("foto/Maurice.jpg"))

PHP file_exists else
