file_exists() function returns true if it does, and false otherwise.

 
Its syntax is: bool file_exists (string file)
<?
$filename = "data.txt";
if (! file_exists ($filename)) :
     print "File $filename does not exist!";
endif;
?>

The file_exists.php script checks to see whether the file is there

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