In your template [0-9]

matches 1 digit, \w

matches another digit, and \d+

matches 1+ digits, which requires 3 digits after #

.

Using

preg_match_all('/Ticket#([0-9]+)/i',$data,$matches);

This will match:

  • Ticket#

    - literal string Ticket#

  • ([0-9]+)

    - group 1, spanning 1 or more digits.


PHP demo :

$data = "Ticket#999999  ticket#9";
preg_match_all('/Ticket#([0-9]+)/i',$data,$matches, PREG_SET_ORDER);
print_r($matches);

Output:

Array
(
    [0] => Array
        (
            [0] => Ticket#999999
            [1] => 999999
        )

    [1] => Array
        (
            [0] => ticket#9
            [1] => 9
        )

)
