Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php
There is no bug here... preg_grep is not meant to return the group
captured data separately... You need to use
preg_match()/preg_match_all() for such.

Description:
------------
I am trying to filter numbers from the end of a string in a array.
i have a array full of these strings :
$testArr = array('foto_1','foto_45');
$resArr = preg_grep('/[0-9]*$/',$testArr);
and the $resArr array that gets returned from preg_grep, contains the
same
strings, i am looking for a array that contains just the numbers that
were
filtered using the regex
Test script:
---------------
<?php
$testArr = array('foto_1','foto_45');
$resArr = preg_grep('/[0-9]*$/',$testArr);
print_r($resArr);
?>
Expected result:
----------------
to see a array full of the numbers what were at the end of the string in
the
input array
something like this :
Array
(
[0] => 1
[1] => 45
)
Actual result:
--------------
Array
(
[0] => foto_1
[1] => foto_45
)
