How do i truncate array keys

Hey there, i am trying to generate a chart based on some array, but to assign the x labels, i need to truncate my keys to 5 characters or something...

so from :

Array ( [Fruits totals] => 61 [Vegetables totals] =&g开发者_开发技巧t; 71) 

to

Array ( [Fruit] => 61 [Veget] => 71) 

thanks in advance.

Just iterate over the array:

$truncated = array();

foreach($array as $key => $val) {
    $truncated[substr($key, 0, 5)] = $val;
} 

Note that two different entries in the original array could have the same truncated key. In this case the last entry will overwrite previous values.
