Checking existence of file

[Exodious]

Hiya, what is the fastest method of checking for the existence of a file?

At the moment, I'm using fopen but if file exists, I'm adding overhead, is there a function in php which will return true or false faster than fopen?

scrap tbat, file_exists

using the file_exists() function maybe?

<?php
$file = "somefileonyourserver.php";
if(file_exists($file)){
echo "$file exists!";
}
else
{
echo "$file does not exist!";
}
?>
