Replacing Backslashes "\"

[Anon]

I want to be able to replace backslashes with forward slashes in PHP4. Can this be done with an ereg_replace command or is there another way to do it?
e.g.
\stuff\hey\atextfile.txt

into

/stuff/hey/atextfile.txt

[johnnyzhu]

<?php

$str="\stuff\hey\atextfile.txt";
$str=str_replace("\","/",$str);
echo $str;

?>
