Hello,
the attached patch adds a flag (SORT_LOCALE_STRING) to our sort
functions that allows the sorting to be done based on the locale
settings. This is important for languages like Norwegian which adds æ, ø
and å to the end of the alphabet, while their iso-8859-1 (the "C"
locale) order is å æ ø.
The working is demonstrated as follows:
<?php
$a = array("ætte", "åtte", "øtte");
$d = $c = $b = $a;
setlocale(LC_ALL, 'C');
sort($a);
sort($b, SORT_LOCALE_STRING);
var_dump($b);
setlocale(LC_ALL, 'no_NO');
sort($c, SORT_LOCALE_STRING);
var_dump($c);
// Words in UTF-8
$d = array("åtte", "Þtte2", "Êtte4", "Þtte1", "Êtte3");
setlocale(LC_ALL, 'no_NO.UTF-8');
sort($d, SORT_LOCALE_STRING);
var_dump($d);
?>
Output:
array(3) {
[0]=> string(4) "åtte"
[1]=> string(4) "ætte"
[2]=> string(4) "øtte"
}
array(3) {
[0]=> string(4) "ætte"
[1]=> string(4) "øtte"
[2]=> string(4) "åtte"
}
array(5) {
[0]=> string(6) "Êtte3"
[1]=> string(6) "Êtte4"
[2]=> string(6) "Þtte1"
[3]=> string(6) "Þtte2"
[4]=> string(5) "Ã¥tte"
}
(The funny chars are UTf8, but it is correct sorting)
I will be committing this patch later, if there are no objections.
