This example demonstrates a possible usage of
locale_set_default() to localize the
sort() functions.
<?php
// the list of the strings to sort
$array = array(
'caramelo',
'cacto',
'caçada'
);
// set our locale (Portuguese, in this case)
locale_set_default('pt_PT');
// sort using the locale we previously set
sort($array, SORT_LOCALE_STRING);
print_r($array);
?>
The above example will output:
Array
(
[0] => caçada
[1] => cacto
[2] => caramelo
)
If we didn't use the locale, PHP would sort the string using the ASCII
characters value, thus returning (wrongly):
Array
(
[0] => cacto
[1] => caramelo
[2] => caçada
)
