Array question

[jstraa]

I want an array that has 9 elements at most, how can I
reduce the array to the 9 FIRST elements? The index association
must remain the same !

Any help is appreciated.

I'm not quite sure what you mean. If you create an array with 9 elements, then that is how many it has.
Are you asking how to get only the first 9 if someone else adds more elements to the array?

i don't know a direct way, just a "not_so_nice" way:

$counter=0;
reset($your_array);
while(list($key,$value) = each($your_array) && $counter<9)
{
  $new_array[$key] = $value;
  $counter++;
}
$your_array = $new_array;
unset($new_array);

if this doesn't work, remove the second condition from the while-condition and add it as if-condition into the while-loop.

exactly, the array is fetched from several queries, and combined, then sorted on relevance. I want to have 9 categories at most, so only the first 9 elements, and delete the rest.

The other option would be

while (count($yourarray) > 9) {
   arraypop($yourarray);
}

array_pop() doesn't work because the association will be lost!

Really? I didn't think it did that. Oh Well, sorry

Heheh yes, but that doesn't leave the index keys as they were.
This seems the exact solution;

function my_pop(&$array)
{

$array = array_reverse($array);

reset($array);
$last = each($array);
unset($array[$last["key"]]);

$array = array_reverse($array);

return

But I don't get how to use it 😉

[jstraa]

but that is still quite a piece of code, is there a way to suggest new functions for PHP?
