Array problem

[madwormer2]

Hey all, I've got an array, and a changes an array to only the even numbered array keys.

function evenNo($ar){

for($i=1;$i<count($ar);$i=$i+2){
unset($ar[$i]);
}

}

$wind = Array('north','north-east','east','south-east','south','south-west','west','north-west');

evenNo($wind);

You see, I'm trying to pass $wind, but I just can't seem to do it. It's a problem that no matter what I do I can't seem to solve.

I've tried dumping it, but it's not helping the problem, because I still can't seem to pass $wind

Any helps will be appreciated, I need a solution, otherwise I may need to explode().

"$wind" is being, um, passed, but into "$ar", which is the array being altered, due to variable scope. To affect the passed variable itself, pass by reference:

function evenNo(&$ar)

I hope this brings some fresh air to your problem.

Lol, I know, I just wrote it as a joke 😉

I got the joke, but replied on the chance the problem was real. Now you should take your medicine. :queasy:
