How to include only if file exists

Question

I need an include function / statement that will include a file only if it exists. Is there one in PHP?

You might suggest using @include bu

Answer 1

Try using file_exists()

if(file_exists($file)){
  include $file;
}

Answer 2

Based on @Select0r's answer, I ended up using

if (file_exists(stream_resolve_include_path($file)))
    include($file);

This solution works even if you write this code in a file that has been included itself from a file in another directory.

Answer 3

I think you have to use file_exists, because if there was such an include, it would have been listed here: http://php.net/manual/en/function.include.php

Answer 4

How about using file_exists before the include?
