What is the difference between these two? 1) <?php include "mypage.php";?> 2) <?php include 'mypage.php';?> Thanx
W3C states that you should use: <?php include("header.php"); ?> I will say that you should use that kind of include
Any parsable characters ($variables, \n, \r) etc will be parsed in DOUBLE quotes. They will NOT be parsed in single quotes. Single quotes are faster - use them - regardless what W3C says.
