php正则怎么取消全局匹配

Question

文本:
exp:funcA(office_province, office_city, office_district, office_street)

正则(自扣的)
/exp:(\w+)(?:\()(.*)(?:\))/

期待提取结果

preg_match('/exp:(\w+)(?:\()(.*)(?:\))/', $exp, $rs);

$rs[0] = funcA
$rs[1] = office_province, office_city, office_district, office_street

Answer 1

$str = 'exp:funcA(office_province, office_city, office_district, office_street)';
preg_match("/^exp:(?P<funcName>\w+?)((?P<param>.+?))$/",$str,$output);
// $output['funcName'] => funcA
// $output['param']    => office_province, office_city, office_district, office_street
