Arrray Help?

Rayn

I want to be able to only output the most values in a array.. like

$this = array("bob","bob","bob","joe","dan","jo");

// something here

echo $ArrayVar; // Outputs bob since bob was in the array the most

Hope you can help with this

Thanks for your time

First part is to use [man]array_count_values[/man] to count the number of occurrences of each value in the array...

Second is [man]max[/man] to find the maximum of those counts...

If you're guaranteed that the most common value will be unique for a given array, or if you only care about getting a most common value, then [man]array_search[/man] will be enough to search for such a key and finish the job...

Otherwise, you can loop through the array and build up a second array containing those keys whose values are maximal:

$most_common = array();
foreach($array_counts as $key=>count)
{ if($count==$max) $most_common[]=$key;
}

just an idea ...
didn't check for PHP functions that could maybe help.

but i think you'll have to create a new array using the variable as key and the number of times it appears as val.

after that all, you'll have to do is check for the key where val is the biggest.

should be easier.

Thanks. Now how would I use max() in this case? And I am not guaranteed the most common result.

Thanks again
