easy question

I can't find this out by searching on google, php.net, etc. I am going
over some php code and don't know to much. When using PEAR packages
there is a lot of =& what does the equal and the ampersand mean in php?

Copy by reference... similar to a pointer in C

<?php
$a=1;
$b =& $a;
$b=5;

echo $a; // results in 5
?>
