Процедурний стиль
Returns a correctly ordered and delimited locale ID the keys identify the particular locale ID subtags, and the values are the associated subtag values.
subtagsAn array containing a list of key-value pairs, where the keys identify the particular locale ID subtags, and the values are the associated subtag values.
Зауваження:
The
'variant'and'private'subtags can take maximum 15 values whereas'extlang'can take maximum 3 values. For instance, variants are allowed with the suffix ranging from 0-14. Hence the keys for the input array can bevariant0,variant1, …,variant14. In the returned locale id, the subtag is ordered by suffix resulting invariant0followed byvariant1followed byvariant2and so on.Alternatively, the
'variant','private'and'extlang'values can be specified as array under specific key (e.g.'variant'). In this case no limits on the number of recognized subtags apply.
The corresponding locale identifier, or false when subtags is empty.

Приклад #3 Subtag limits
If subtags are given as separate keys with numeric suffix,
unsupported keys are silently ignored (in this case 'extlang3'),
and ordered in the result by numeric suffix.
There are no limits, if subtags are given as array; the order is as given.
<?php
$arr = array(
'language' => 'en',
'script' => 'Hans',
'region' => 'CN',
'extlang3' => 'd',
'extlang2' => 'c',
'extlang1' => 'b',
'extlang0' => 'a',
);
echo locale_compose($arr), PHP_EOL;
$arr = array(
'language' => 'en',
'script' => 'Hans',
'region' => 'CN',
'extlang' => ['a', 'b', 'c', 'd'],
);
echo locale_compose($arr), PHP_EOL;
