mmorpg small error help

[tbales]

hello,
im slowly leaning how to code but i run a mmorpg and i need help with my "expirence" codes.

problem: i cant get the EXP (expirence) to go back to "0" after the previous required exp has been met if you need more information please ask

function experience($L) {

  $a=0;

  $end=0;

  for($x=1; $x<$L; $x++) {

$a += floor($x+2000*pow(4, ($x/7)));

  }

 return floor($a/4);

}



function Get_The_Level($exp) {

  $a=0;

  $end=0;

  for($x=1; ($end==0 && $x<100); $x++) {

$a += floor($x+2000*pow(4, ($x/7)));

if ($exp >= floor($a/4)){

} else {

  return $x;

  $end=1;

}

  }

}



function Get_Max_Exp($L){

$end=0;

 if ($exp == 0){

return 457;

$end =1;

  }

for($L=1;($L<100 && $end==0);$L++) {

  $exp = experience($L);

  //echo $exp;

  if ($exp >= $user_class->exp){

	return $exp;

	$end=1;

  }

}

}

where you want to use $end ?

Lets change this $end, then return from the function, but $end is a local variable, so you have to add
into your return to be able to use it outside.

i dont understand can someone put what ever he said in the code and repost it

[djjjozsi]

why don't you start with a smallest function? Then learn how to use a variable inside a function, and how could you return this variable. http://hu2.php.net/manual/en/functions.returning-values.php

This function never do anything, just return 457

function Get_Max_Exp($L){
$end=0;
if ($exp == 0){
    return 457;
    $end =1;
  } 

This code is doing this :
lets add a value to $end, which is 0
if $exp is equal with 0, then return 457! Hey! $exp is always equal with 0, so i always return 457. As i see, in the next line i shoud create another value for $end, but i've returned so i can't do that!

You code is full of undefined variables, if you want to know which are, lets use error reporting:

error_reporting(E_ALL);

so that entire code is wrong or can you fix it?
