  • Question 5/55

    PHP assigns non-object variables by value, but you can "connect" one variable to another so assignment occurs by reference instead. What is output of the following PHP script?

    
    <?php
        $a 15;
        $b $a;
        $b 25;
    
        $c 50;
        $d = &$c;
        $d 25;
    
        echo $a ' - ' $c;
    ?>
    
    
    Enter the exact script output
