array function

[asa_carter]

Hi,

Can anyone see what is wrong with this? I cant find the right functions to remove the current element in an array and insert a new value in its place...

// if array already exists 
if($pages) 
{ 
  // itterate through array 
  while (list($catnum, $howmany) = each ($pages)) 
  { 
    // if the current page id is in the array 
    if ($id==$catnum) 
    { 
      // increment the current array element 
      $howmany++; 
      // remove the current array element 
      ????? 
      // add the new value to the current array 
      ?????? 
    } 
  } 
}

Is this what you're trying to do?

// if array already exists
if($pages) 
{ 
  // itterate through array
  while (list($key, $value) = each ($pages)) 
  { 
    // if the current page id is in the array
    if ($id==$key) 
    { 
      $pages[$key] = $whatevernewvalue;
    } 
  } 
}

Hi,

Would that replace 100000 => 1

with 100000 => 2

if I incremented $value?

Thanks,

Asa.

Your original statement was that you wanted to

...remove the current element in an array and insert a new value in its place...

Maybe I don't understand what it is you're trying to do. What I wrote will just walk across your array and replace the value of $pages[$i] with $whatevernewvalue if $i == $id.

Maybe you can explain what it is specifically you're trying to do.

ok, basically what I am trying to do is create a favourite category's section on my front page.

www.argyllnewmedia.co.uk/marketplace2/

when a user clicks on a category they are taken to the next page- browse.php?id= (category number eg.100000)

I want to count how many times the user chooses each category and display the top 5 or so on the front page by storing them in a cookie.

Thanks

Asa

$pages[$id] = $pages[$id]++;
