How to Create a file, then write to it?

[benphp]

I can use this code to write to an EXISTING file, but when I try to use it to CREATE a file, it fails - or rather, it doesn't do anything - not even throwing an error. What am I doing wrong?

 

<?php
$path = "";
$filename = "myfile.txt";
$fp = fopen($path.$filename, 'w') or die("Sorry charlie"); 
flock($fp, LOCK_EX);
fwrite($fp, "I like almonds");
flock($fp, LOCK_UN);
fclose($fp);
?>

 

Thanks!

Nevermind - it doesn't like flock. Why would flock screw it up?
