file_exists in php code

Question

I have a simple statement below:

if(file_exists('/images/alum/'.$profile['pic'])) 
  echo '/images/alum/'.$profile['pic']; 
  else echo '/images/user_default.jpg';

The file is there but it's always going to the default image. What have I got wrong?

I would advise to do some reading about relative and absolute paths - both file paths (path of file that resides on filesystem) and URL paths (address that is being used with <a href=''></a> and other HTML tags). After reading about it, you should understand and be able to tell when (and why) to use ./images/, images/ or /images/. — binaryLV

You are saying on the server that the file at the root of the file system exists. You will have to probably add some . or ..

Try:

if(file_exists('./images/alum/'.$profile['pic']))
 echo '/images/alum/'.$profile['pic']; 
 else echo '/images/user_default.jpg';

i.e. changing the "/images" to "./images" but only in the file_exists call.

Change it to this.

if(file_exists('./images/alum/'.$profile['pic'])) 
    echo './images/alum/'.$profile['pic']; 
else 
    echo './images/user_default.jpg';

make sure that $profile['pic'] has valid file name, contraction with path is valid, and current directory with parth point to file...

temporary negate condition to see file from profile...
