only do foreach loop for specific key array php

 $v) {
    echo "Current value of \$a: $v.\n";
}

?>

Here is what the above code is Doing:
1. We create an array called $a.
2. We use foreach to loop through the array.
3. We use $index to get the index of the current element.
4. We use $v to get the value of the current element.
5. We print out the current value of $a.
