pass-by-reference depricated

[SubZane]

Since pass-by-reference has been depricated I'm looking for an alternative, my problem is this:

function ($var1 , $var2, @$feedback) {
if ($var1 != $var2) {
$feedback = 'no'
} else {
$feedback = 'yes'
}
}

anyway I can do this by using my feedback var?

Just make the function return something.

function ($var1 , $var2)
{ 
    return ($var1 != $var2 ? "no" : "yes")
}

yes i know, but what if I want to return 2 values, one with the feedback and one with the value?

You can do this, although pass-by-reference would be much nicer:

class somedatatype
{
    var $var1;
    var $var2;
}

function somefunction ($var1, $var2, $feedback)
{
    $toreturn = new somedatatype();
    if ($var1 != $var2)
    { 
        $toreturn->feedback = 'no';
    }
    else
    { 
        $toreturn->feedback = 'yes';
    }
    $toreturn->var1 = $var1;
    $toreturn->var2 = $var2;
    return $toreturn;
}

Zane,

Use return array such as:

function testies($var1 , $var2, $feedback) {
if ($var1 != $var2) {
$feedback = 'no'
} else {
$feedback = 'yes'
}
return array ($var2, $feedback);
}
list ($value2, $feedback) = testies($value1, $value2, $feedback);

OR

use the global keyword:

function testies($var1 , $var2) {
global $feedback;

if ($var1 != $var2) {
$feedback = 'no'
} else {
$feedback = 'yes'
}
}

Hope this helps,
Tom 🙂
