How to use a value from one foreach loop in the second one?

I would like to know how to the following: I have 2 foreach loops, one inside the other. For example:

foreach($a as $b) { 
    foreach($c as $d) { 
        echo $b; 
    }
}

Now this code snippet doesnt make any sense, but what I would like to know is how to get the value of the first foreach loop (here the $b) into the second foreach loop. Because in this example the $b would not be outputted.

So how can I kind of set the variable $b as global in order to use it in the second foreach loop?

$b is accessed as many time as you inner loop 'loops'.

Check first whether or not you loops run correctly...start with the outer one, than check the inner one...if that is all ok, you must be able to succesfully print a variable from the outer loop scope.

Learn something about scoping http://php.net/manual/en/language.variables.scope.php

As you will read, it's already accessible.

It's already accessible.

foreach($a as $b) { 
    foreach($c as $d) { 
        echo $b; //  $b can be accessed
    }
}

You don't need to do that, $b will be accessible in the inner loop by default.
