Please replace your code with below code.

<?php

$curr_url = $_SERVER['REQUEST_URI'];
$exp_url = explode('/', $curr_url);
//print_r($exp_url);

$classType = 'tool-another';
if(!empty($exp_url) && isset($exp_url[2]) )
{
    if($exp_url[2] == 'xyz.html' || $exp_url[2] == 'xyz'){
        $classType = 'xyz';
    } elseif($exp_url[2] == 'abc.html' || $exp_url[2] == 'abc'){ 
       $classType = 'abc xyz';
    }
}

?>
