Matching the url based on the page the user is on - php

Question

I'm trying to right a simple if statement to basically say that if the user is on page_A then echo "i am on page A"; and if I'm on page_B then echo "i am on the page B"; and I'm using the PHP function $_SERVER['REQUEST_URI']; to check if they match what is in my string that is stored in the variable $page_A and $page_B.
my code is as follows:
<?php
$page_A = "/test.co.za/voice/";
$page_B = "/test.co.za/artistes/";
$match = $_SERVER['REQUEST_URI'];
if ( $page_A == $match ) {
echo "i am on page A";
}elseif ( $page_B == $match ) {
echo "i am on the page B";
}
?>
Where am i going wrong or is there another way i can achieve getting this to work?
Thanks team :)

Answer 1

if(strpos($_SERVER['REQUEST_URI'],'voice')!==false){
echo "i am on page A";
}elseif(strpos($_SERVER['REQUEST_URI'],'artistes')!==false){
echo "i am on the page B";
}

I don't quite understand how you are doing this, if you have 2 different pages you always know at which page you are.
If you are using htaccess to redirect the request to a unique file, you should do something like this:
Add this line in htaccess:
RewriteRule ^([0-9a-zA-Z-_]*)\/?([0-9a-zA-Z-_]*)\/?([0-9a-zA-Z-_]*)\/?([0-9a-zA-Z-_]*)\/?$ index.php?p=$1&s=$2&d=$3&ID=$4&%{QUERY_STRING}
Now, if you open for instances: http://test.co.za/voice/ this will be redirected to /index.php.
At index.php you can read:
$page = $_REQUEST['p'];
if ($page == 'voice') { //do stuff }
