Getting multiple subpatterns with the same name - php

Question

Regarding my previous post I'm trying to match with regular expressions all use statements in a class file.
<?php
use Vendor\ProjectArticle\Model\Peer,
Vendor\Library\Template;
use Vendor\Blablabla;
$file = file_get_contents($class_path);
$a = preg_match_all('#use (?:(?<ns>[^,;]+),?)+;#mi', $file, $use);
var_dump(array('$a' => $a, '$use' => $use));
Unfortunately I'm not blessed with all namespaces used in case of multiple class names in one use statement. Only last one matched is being stored.
Array
(
[$a] => 2
[$use] => Array
(
[0] => Array
(
[0] => use Vendor\ProjectArticle\Model\Peer,
Vendor\Library\Template;
[1] => use Vendor\Blablabla;
)
[ns] => Array
(
[0] =>
Vendor\Library\Template
[1] => Vendor\Blablabla
)
[1] => Array
(
[0] =>
Vendor\Library\Template
[1] => Vendor\Blablabla
)
)
)
Can this be accomplished with some pattern modifier or something?
~Thanks

Should be able to use the \G anchor for this.
# '~(?:(?!\A)\G|^Use\s+),?\s*(?<ns>[^,;]+)(?=(?:,|[^,;]*)*;)~mi'
(?xmi-) # Inline modifier = expanded, multiline, case insensitive
(?:
(?! \A ) # Not beginning of string
\G # If matched before, start at end of last match
| # or,
^ Use \s+ # Beginning of line then 'Use' + whitespace
)
,? \s* # Whitespace trim
(?<ns> [^,;]+ ) # (1), A namespace value
(?= # Lookahead, each match validates a final ';'
(?: , | [^,;]* )*
;
)
Output:
** Grp 0 - ( pos 0 , len 36 )
use Vendor\ProjectArticle\Model\Peer
** Grp 1 - ( pos 4 , len 32 )
Vendor\ProjectArticle\Model\Peer
---------------------
** Grp 0 - ( pos 36 , len 30 )
,
Vendor\Library\Template
** Grp 1 - ( pos 43 , len 23 )
Vendor\Library\Template
---------------------
** Grp 0 - ( pos 69 , len 20 )
use Vendor\Blablabla
** Grp 1 - ( pos 73 , len 16 )
Vendor\Blablabla
