Array (6) {
  [0]=>
  String (62) ": /.. /dat/dig/testfunction/ts407/bed410-500a1/5306/ng/7020.csv "
  [1]=>
  String (64) ": /.. /dat/dig/testfunction/ts407/bed410-500a1/5306/ng/7020_1.csv "
  [2]=>
  String (64) ": /.. /dat/dig/testfunction/ts407/bed410-500a1/5306/ng/7020_2.csv "
  [3]=>
  String (64) ": /.. /dat/dig/testfunction/ts407/bed410-500a1/5306/ng/7020_3.csv "
  [4]=>
  String (64) ": /.. /dat/dig/testfunction/ts407/bed410-500a1/5306/ng/7020_4.csv "
  [5]=>
  String (65) ": /.. /dat/dig/testfunction/ts407/bed410-500a1/5306/ng/7020_ng.csv "
}

Known quantity the form of group A, if you think of a file starting with 7020 as a file, the result is: Ts407,bed410-500a1,5306,ng corresponds to a number of 1. How can I ask for it?

Preg_match ('/^ (\d+) (\.

$arr _file[]= $m [1];
}
$count =count (Array_unique ($arr _file));
echo $count;//2
