getting the first value alphabetically

[hungryfrank]

i have this code that enters the values of an array into my db

foreach ($results->CategoryArray->Category as $key => $value) { 
$categories_ids = (int) $value->CategoryID;
$CategoryName=$value->CategoryName;
if(strcmp($first_name,$CategoryName) <0)$firstID=(int) $value->CategoryID;
/// other codes to enter in db
}
echo $firstID

i want to get the value of $categories_ids when the $CategoryName is alphabetically first.  but it don't work. i always get the last value of the last one in the array.

You're comparing with $first_name but you never update that value.

Here's an alternative approach

$category = [   1 => 'kiwi',
                2 => 'lemon',
                3 => 'apple',
                4 => 'pear'     ];

asort($category);                            // sort them, preserving keys
list ($id, $cat) = each($category);          // get the first
echo "$id : $cat";                           // --> 3 : apple
