HTTP authentication via php?

[GhOsTTeCh]

basicly i set up a little script to go to an address 10 times, this address needs to be logged (like the .htpasswd way) in (its cpanel).
how would i go about logging in progrmaticly?? thanks

<?php
$i = 10;
$p = 1;
while ($p < $i){
	
file_get_contents("http://REMOVED");
echo "Did URL " . $p . "<br />";

$p++; };
?>

also very sorry for the lack of punctuation/spelling and lack of terminology im very tierd and want to get this over and done with.
