<?php
$path=$PHP_SELF;
//$PHP_SELF is "/star/index.php"
$path=explode("/",$path)
//so $path[1]should be "star"
$url="star";
if(strcmp($url,$path[1])==0)
echo "ok";
// why "ok" was not displayed ????
// and then I used this to check
echo $path[1];
// "star" was displayed.as expected!!
echo strlen($path[1]);
// 0 was displayed why.
?>
thanks !!
