Thread: Only use default value for some of the arguments

  1. #1

    Only use default value for some of the arguments

    How do I specify that I want to use the default values for the first two arguments but not the last argument?

    PHP Code:
    function doStuff($a 1$b 2$c 3) {
       echo 
    $a $b$c;
    }

    // psuedo-code:
    doStuff(DEFAULT, DEFAULT, 99); 

  2. #2
    You can't. It's inherent to the way arguments are passed on the stack. See also http://www.php.net/manual/en/functions.arguments.php

    You really should reconsider your function definitions if you need this kind of functionality. If you really want to do it like this, you could assign default values null and then pass those:

    PHP Code:
    function doStuff($a null$b null$c null) {
        
        
    $a = ($a === null $a);
        
    $b = ($b === null $b);
        
    $c = ($c === null $c);
        
        echo 
    $a $b $c;
        
    }

    doStuff();
    doStuff(nullnull5);
    doStuff(null34); 
    Wait, what?
