Match select text between delimiter

For some reason my regex is matching what I am after and extra. I am needing to just match the group #, but it's matching the first number of the phone numbers also.

Example data:

id: N group: 1 category: NAMES : Mike
id: N group: 2 category: NAMES : Seth
id: # group: 1 category: PHONE : 123-456-789
id: # group: 2 category: PHONE : 111 111-1111
id: @ group: 1 category: EMAIL : [email protected]
id: @ group: 2 category: EMAIL : [email protected]

Regex

preg_match_all('/:\s+\d/', $data, $matches);

Current output

1
2
1
1
2
1
1
2

Expected output

1
2
1
2
1
2

You can use the following, which will also exclude the whitespace and give you your exact match.

preg_match_all('/(?<![^ ])\d(?!\d)/', $data, $matches);

See live demo

Or to be safe, you could just use a look ahead.

preg_match_all('/\d(?= +category)/i', $data, $matches);

See live demo

Better yet, just simply match for group: and the following number.

preg_match_all('/group:\s+\K\d/i', $data, $matches);

Change your regular expression through

"/group:\s*(\d+)/i"

The issue is that you have also ":" after PHONE and EMAIL

You could do a lookahead, to make sure that category follows immediately:

preg_match_all('/:\s+\d(?= category)/', $data, $matches);

The lookahead is not captured, but strings won't match if it isn't there.
