I'm currently using this snippet on my site... the problem? I DON'T GET ANY OF IT!

i have it working properly, but can anyone simplify it for me please?

The first two seem to be extremely convoluted ways of doing this:

[math]experience(L) = 500L[/math]

[math]L(experience) = \left\lfloor \frac{experience}{500} \right\rfloor + 1[/math]

 

Or in PHP...

 

function experience($L)
{
return 500 * $L;
}


function Get_The_Level($exp)
{
return floor($exp / 500) + 1;
}

 

The last one is broken, so it effectively always returns the integer 457 and makes an E_NOTICE about $exp not being set. Assuming it worked, I would expect it could also be written in a normal mathematical fashion.

After playing around alot I came to this conclusion

 

<?php
//level 2 - 500    

//level 3 - 1500   

//level 4 - 3500   

//level 5 - 6000 

function getExp($level) {
    if ($level==2) return 500;
    $product = 0;
    for ($i=3;$i<=$level;$i++) {
         $product += $i * 500;      
    }
    return $product;
}

function getExpLevel($exp)
{
    if ($exp<1500) return 2;
    $product = 0;
    $next = 0;
    for ($i=3;$i<=10;$i++) {
         $next += $i * 500;
         if ($exp > $product && $exp < $next) { return $i;}
         $product = $next;
    }

}
echo getExp(5);
echo "<br />";
echo getExpLevel(5000);

?>
