file_exists not working with localhost URL

Question

I have this piece of code in PHP:

if (file_exists($_POST[\'current_folder\'])) {
    //do something
} 

But file_exists always retu

Answer 1

Use directory path; not web URL:

<?php
$filename = '/path/to/foo.txt';

if (file_exists($filename)) {
   echo "The file $filename exists";
} else {
   echo "The file $filename does not exist";
}
?>

Answer 2

Tested under windows using Apache 2.4.9.

<?PHP
$crl = curl_init("http://localhost/symfony2/");
curl_setopt($crl, CURLOPT_NOBODY, true);
curl_exec($crl);

$ret = curl_getinfo($crl, CURLINFO_HTTP_CODE);
curl_close($crl);

if ($ret == 200)
    echo 'File exists';
else
    echo 'File does not exist';
?>

It works, just a note, it requires trailing slash for some reason.

Code 200 means OK (success).
