creating an item inventory - HTML Forums

rorypickering · 10-30-2009, 08:53 AM

can i have suggestions on best way to this

how can i determine what items a user has from the inventory array?

e.g. '4,4,5,4,4,4';

i know that i habve to explode the string at ',' but how what code do i need to write so it says,

item number 4 , you have 5.
item number 5, you have 1.

so i need it to count each number and do a mysql query to fetch the info about that item and say how many this user has???

cheers

PHP Code:


			
$str ='4,4,5,4,4,4';



$exp = explode(",",$str);

//array to hold the numbers

$nums = array();

//loop trought the array

foreach($exp as $v)

{

   //we insert the exp v as index and count how meny times it's been looped

   if(!isset($nums[$v]))

    $nums[$v]=0;

   else

   $nums[$v]++;

}



foreach($nums as $k=>$v)

{

  echo $k."=".$v;

}

Something like that?
