Question

i have got an associative array as follows:

$data['england']='pound'
$data['america']='dollar'
$data['europe']='euro'
$data['denmark']='krone'
$data['japan']='yen'

I want to sort this array and after that i want ‘europe’ to be the first element in the array. To sort the array, i am using ksort() in php, now how can i get hold of the ‘europe’ array object so that i can make it the first element and shift all the remaining elements down?

Answer 1

One solution would be to first remove europe from the array and then do the ksort. When the array is sorted you can use the array_unshift() or array_merge() to add europe as the first element in the array.

An example using merge:

<?php
$data['england']='pound';
$data['america']='dollar';
$data['europe']='euro';
$data['denmark']='krone';
$data['japan']='yen';

unset($data['europe']);
ksort($data);
$data = array('europe' => 'euro') + $data;

print_r($data);
?>

Usage of the + operator will not reindex the array as the merge-operator would.
