Ok I have an array thats created in a loop session:
$countuid[] += $uid;I want to ask if the array key $uid matches more than once in the array .......'do something'
I cant work it out Ive been looking at 'array_key_exists' but cant seem to find the right syntax for the if statement.
My array is coming out as: Array ( [0] => 54 [1] => 54 [2] => 54 [3] => 55 [4] => 55 )
But as I said its in a session so that will change.
You are not really setting any keys, if you want to do something on a value existing in the array, use array_search().
Depending on what it is you are trying to accomplish, you could use [man]array_filter[/man] after the fact to eliminate duplicate values in the array.
Instead of this (which does not seem to make sense in any case):
$countuid[] += $uid;
use this:
$countuid[$uid] = $uid;
then you can use
if(array_key_exists($uid, $countuid)
{
// do something
}
Thank you very much thats much appreciated!!
I spent far to long on that yesturday, I knew it was something fairly simple!
I tried something very close to that but couldn't work it out.
That was nearly the last of my pig of a shipping cost script!
Thanks thats just great!
