You need to use a second foreach.

<?php
$path = array("Login", "Register");
$list = array("Admin", "Customers", "Guest");

foreach ($path as $p) {
    foreach ($list as $l) { 
        echo "Var " . $p . " is " . $l . "\n";
    }
}

If you just want to walk over array you can use foreach loop:

foreach ($path as $p) {
    $row = 'Var ' . $p . ' is ';
    foreach ($list as $l) {
        echo $row . $l . "\n";
    }
}

where first loop walks through vars and then inner loop uses every var for every list item

$path = array("Login", "Register");
$list = array("Admin", "Customers", "Guest");

for ($i=0; $i<count($path); $i++) {
    for($j=0;$j<count($list);$j++){
       echo "Var " . $path[$i] . " is " . $list[$k] . "\n";
    }
}

Hope this will help you

<?php
$path = array("Login", "Register");
$list = array("Admin", "Customers", "Guest");

foreach ($path as $row) {
    foreach ($list as $data) {
        echo "Var " . $row . " is " . $data . "\n";
        echo '<br />';
    }
}

You just need a double foreach loop to parse the arrays.

The output is :

Var Login is Admin 
Var Login is Customers 
Var Login is Guest 
Var Register is Admin 
Var Register is Customers 
Var Register is Guest
