$subtags
) : stringReturns 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.
Note:
The 'variant' and 'private' subtags can take maximum 15 values whereas 'extlang' can take maximum 3 values.e.g. Variants are allowed with the suffix ranging from 0-14. Hence the keys for the input array can be variant0, variant1, ...,variant14. In the returned locale id, the subtag is ordered by suffix resulting in variant0 followed by variant1 followed by variant2 and so on.
The 'variant', 'private' and 'extlang' multiple values can be specified both as array under specific key (e.g. 'variant') and as multiple numbered keys (e.g. 'variant0', 'variant1', etc.).
The corresponding locale identifier.

<?php
$arr = array(
'language'=>'en' ,

'variant2'=>'rozaj' ,
'variant1'=>'nedis' ,
'private1'=>'prv1' ,
'private2'=>'prv2'
);
echo locale_compose( $arr );
?>
