从字符串中提取票号

Question

I want to extract the ticket numbers from a string that contains numbers and letters like:

String 1) Order 2555225552 Ticket Number [TICKET 201805000000012345]
String 2) Order 32234234234 Ticket Number [TICKET <span>201805000000012345</span>]
String 3) Order 5656567655665565 Ticket Number [  TICKET <span>   201805000000012345</span>   ]

I want here to get the number 201805000000012345 or any other number from input string (1, 2 or 3).

---

$matches = array();
preg_match('/\[TICKET(.*)([0-9]+)(.*)\]/', 'Ticket Number [TICKET <span>201805000000012345</span>]', $matches);

Output:

array:4 [
  0 => "[TICKET <span>201805000000012345</span>]"
  1 => " <span>20180500000001234"
  2 => "5"
  3 => "</span>"
]

Answer 1

Your regex is mostly correct. You just need to add a ? to make it non-greedy.

/\[TICKET(.*?)([0-9]+)(.*)\]/

In fact, if you don't care about what comes after the numbers, you can also omit that part:

/\[TICKET(.*?)([0-9]+)/
