POHow to sort an array of UTF-8 strings?
text
Body
copied!<p>I currentyl have no clue on how to sort an array which contains UTF-8 encoded strings in PHP. The array comes from a LDAP server so sorting via a database (would be no problem) is no solution. The following does not work on my windows development machine (although I'd think that this should be at least a possible solution):</p> <pre><code>$array=array('Birnen', 'Äpfel', 'Ungetüme', 'Apfel', 'Ungetiere', 'Österreich'); $oldLocal=setlocale(LC_COLLATE, "0"); var_dump(setlocale(LC_COLLATE, 'German_Germany.65001')); usort($array, 'strcoll'); var_dump(setlocale(LC_COLLATE, $oldLocal)); var_dump($array); </code></pre> <p>The output is:</p> <pre><code>string(20) "German_Germany.65001" string(1) "C" array(6) { [0]=> string(6) "Birnen" [1]=> string(9) "Ungetiere" [2]=> string(6) "Äpfel" [3]=> string(5) "Apfel" [4]=> string(9) "Ungetüme" [5]=> string(11) "Österreich" } </code></pre> <p>This is complete nonsense. Using 1252 as the codepage for <code>setlocale()</code> gives another output but still a plainly wrong one:</p> <pre><code>string(19) "German_Germany.1252" string(1) "C" array(6) { [0]=> string(11) "Österreich" [1]=> string(6) "Äpfel" [2]=> string(5) "Apfel" [3]=> string(6) "Birnen" [4]=> string(9) "Ungetüme" [5]=> string(9) "Ungetiere" } </code></pre> <p>Is there a way to sort an array with UTF-8 strings locale aware?</p> <p><em>Just noted that this seems to be PHP on Windows problem, as the same snippet with <code>de_DE.utf8</code> used as locale works on a Linux machine. Nevertheless a solution for this Windows-specific problem would be nice...</em></p>
