PHP - file_exists doesn't work even if file exists in directory

Question

Im trying to verify if file exists in directory. When I use this code it works - image is displayed:

<?php 

  $imgId=0; 
  $filename='../uploadedimages/project-'.$item->id.'-'.$imgId;

  echo "<img src='".$filename."' ></img>";

?>

When I use the same code with file_exists function, it doesn't work:

<?php 

  $imgId=0; 
  $filename='../uploadedimages/project-'.$item->id.'-'.$imgId;

  if (file_exists($filename)) {                             
    echo "<img src='".$filename."' ></img>";                
  }

?>

My question is simple: WTF??

Your documentroot is not the same as the server documentroot... So `file_exists()` uses the folder where the script resides in as the reference directory. Loading the `` takes it referenced from the root of your webserver. — RichardBernards, Dec 03 '14 at 14:52
Read the *"WTF"* manual http://php.net/manual/en/function.file-exists.php ;) `$filename='/var/user/you/httpdocs/uploadedimages/project...` — Funk Forty Niner, Dec 03 '14 at 14:54
I though this is filesystem path. What is filesystem path then? — Tomas Turan, Dec 03 '14 at 14:55
`$filename='/var/user/you/httpdocs/uploadedimages/project...` <= *that*. — Funk Forty Niner, Dec 03 '14 at 14:59
Z:\kvetena.local\web\uploadedimages\ - this is my current filepath, but it can be changed in future. What should I do then? — Tomas Turan, Dec 03 '14 at 15:04

You can use: $_SERVER['DOCUMENT_ROOT'] to know where you are.

And then try something like this:

$filename=$_SERVER['DOCUMENT_ROOT'].'uploadedimages/project-'.$item->id.'-'.$imgId;

But first you need to make sure the path exist.

on linux server, try to change file access permission to 755 before using file_exists function

chmod 755 filename.ext
