Question

So i’ve got an array that looks something like of:

Array ( [Safari] => 13 [Firefox] => 5 )

How do i a make a new array that looks like :

Array ( [Safari] => 72.2% [Firefox] => 27.7% )

using a neat php function?

thanks in advance.

You can use array_sum() to get the total, then iterate over the values returning the new value.

$total = array_sum($share);

foreach($share as &$hits) {
   $hits = round($hits / $total * 100, 1) . '%';
}

If you have >= PHP 5.3 it can be a tad more elegant with an anonymous function.

$total = array_sum($share);

$share = array_map(function($hits) use ($total) {
   return round($hits / $total * 100, 1) . '%';
}, $share);
