Question

I have an array that I need to re-order. It is an array of country codes:

$countries = array('uk', 'fr', 'es', 'de', 'it');

I need to sort the array with a particular user selected country first, ie. ‘fr’ and the remaining items need to be in alpabetical order.

I am not too sure how to do this, any help would be appreciated.

Answer 1

$countries = array('uk', 'fr', 'es', 'de', 'it');
// find and remove user value
$uservar = 'uk';
$userkey = array_search($uservar, $countries);
unset($countries[$userkey]);
// sort ascending
sort($countries,SORT_ASC);
// preappend user value
array_unshift($countries, $uservar);
