In your pattern [0-9] matches 1 digit, \w matches another digit and \d+ matches 1+ digits, thus requiring 3 digits after #.

Use

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

This will match:

  • Ticket# - a literal string Ticket#
  • ([0-9]+) - Group 1 capturing 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
        )

)
