Need Help Debugging Code

[Sinzygy]

Okay, I got this function to calculate the experience.
I can input the attacker level, the defender level and wheter it's a match against a trainer or against a player.
here's the function:

Code: [Select]

function experience($alvl,$dlvl,$t)
{
if($t == 1)
{
$exp = rand(($dlvl * 19),($dlvl * 19) + rand(0,2*$dlvl));
$silver = round(rand($dlvl*1.5, 2 * $dlvl));
}
else
{
$exp = round($dlvl * 40 * ($dlvl / $alvl));
if($dlvl == $alvl) $exp = round($exp * 1.5);
elseif($dlvl > $alvl) $exp = $exp * 2;

$silver = round((2/3) * $exp);

}

$ret['silver'] = $silver;
$ret['exp'] = $exp;
return $ret;
}

But this doesn't work and I dont know why! If i take out the lines $ret[silver] = $silver; and $ret[exp] = $exp; in the else {} statement, it works. If I leave them in, it wont work. Meaning it won't work as in the whole page is blank (this is a function in a file that gets included on every page)

Can anyone tell me what's wrong here? (I've had this problem mutliple times now with the same method of returning an array by a function. Sometimes it worked when I put one line before the other, but not the other way around... I'm getting confused here)

I'm still getting used to PHP syntax but shouldn't you use double quotes "" in the array

Instead of this:

Code: [Select]

$ret['silver'] = $silver;
$ret['exp'] = $exp;
This:

Code: [Select]

$ret["silver"] = $silver;
$ret["exp"] = $exp;
Just my first thought.

doesn't work neither with double-quotes (""), single quotes ('') nor nothing ().

[Zeggy]

Using single or double quotes shouldn't matter in arrays I use single-quotes personally, but I see other people use double quotes.

I'm not sure what's wrong, but it might not be this particular code that is the problem. I used the code and tested it on a single PHP page, like this:

<?php
//your function here

$a = experience(20,30,1);
print_r($a);
?>

I get "Array ( [silver] => 52 [exp] => 570 )" or similar returned using different values in the function. I don't get any errors at all.
Or maybe I am using the function in a wrong way?

[Broda]

Maybe it's the way the page is included?

Try using require_once("file.php")

[Sinzygy]

Broda: still nothing.

I use an include('file.php'); in the template. But I really don't think this is the problem.
And Zeggy: yes, I assume it will work, since I can't find any errors in the code itself. But it isn't working for me and I don't know why... its a realy bummer

[Sinzygy]

okay, I finally managed to get it working:

instead of inserting each one by itself it made

Code: [Select]

$ret = array("exp"=>$exp,"silver"=>$silver);
return $ret;

that seemed to work... still haven't figured out why tho

maybe it was because I only ran it on my local machine and there might be some faulty setup. But I really wouldn't know how this could've happened...

[Broda]

Strange. Glad you got it working though
