locale_set_default — Set the default Locale
Sets the default Locale for PHP programs. Please note that this has nothing to do with setlocale() nor with the system locale.
The new Locale name. A comprehensive list of the supported locales is available at » http://demo.icu-project.org/icu-bin/locexp.
如果成功则返回 TRUE，失败则返回 FALSE。
Example#1 A locale_set_default() example
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);
?>
上例将输出：
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 )
