Are PHP variables declared inside a foreach loop destroyed and re-created at each iteration?

Question

If I declare a variable inside a foreach loop, such as:

foreach($myArray as $myData) {
    $myVariable = \'x\';
}

Does PHP destroy it, and

Answer 1

According to the debugger in my IDE (NuSphere PHPed) in your first example:

foreach($myArray as $myData) {
    $myVariable = 'x';
}

$myVariable is only created once.
