PHP Return Variables

Return Variables With PHP

With PHP, you can return one variable or an array from a function. The example below explains how to retun a single variable.

function add_numbers($number_one,$number_two){
    $mytotal = $number_one + $number_two;
    echo $mytotal;
    return $mytotal;

$num1 = "1";
$num2 = "2";

//The function will make variable called $mytotal which can be returned from the function
$total = add_numbers($num1,$num2);
echo "<br/><br/>";

//$total is setting the variable equal to the function
//The value $mytotal is returned and is printed below
echo "The total $total is returned from the function which can only return a single variable or array. In this case, the function returns a variable.";
