PHP Return Values Statement
What is Returning Values?
Explanation
Values are returned using the statement return(), this statement ends the code execution and passes the control to the line from which it was called. Any values can be returning like arrays, objects.
Syntax:

In the above syntax the return statement can return a value or it can be without a value.
Example :
<?php
function sub($first,$second)
{
$total = $first - $second;
return $total;
}
$first = "3";
$second ="2";
$total = sub($first,$second);
echo "$total";
?>
Result :

In the above example the function sub returns the value "$total", when the function is called the subracted value of 3 and 2 is returned as 1.
