while statement

argh this dumb script is pissing me off, im just trying to search a diretory for a file and determine if it exists, but no matter what i put $go as ($go is the filename im searching for) it always says its successful. if anyone could tell me what im doing wrong i would really appreaciate it.

heres my code:

<?
$x="0";

$directory = opendir("files/");
  while($filename = readdir($directory))
{ 
	if ($filename="$go.dat") {
	$x="1";
	break;
}
}
closedir($directory);

if ($x==0) {
	echo "not found";
} else if ($x==1) {
	echo "success";
}
?>

The bug is in this line:

if ($filename="$go.dat") {

But see also the file_exists() function.

Well, if you know the name of the file, and the directory that it resides in, why don't you use the file_exists() function instead of dorking around with opendir() and readdir()?

$dir = "files/";
$file = "go.dat";
if(file_exists($dir . $file)) {
	// file exists conditional shtuff in here
}
