php正则表达式匹配文本

Question

I need a php regex to match text that is not preceded by the name "Total" of "maximum" case insensitive in the text below.

[1]
[1m]
[1mk][1mks]
[1mark]
[1marks]
(1mk) 
12mk

12 mark
13 mark
[Total: 15]
Total: 16 mark
Total 1 mark
Total 12 mark
Total: 9 mark
Total: 10 mark
[Total: 11 marks] Total 6 mark
maximum 5 marks
maximum:5 marks

Note: This text is in a one long line.

The regex should match the following

[1]
[1m]
[1mk][1mks]
[1mark]
[1marks]
(1mk) 
12mk

12 mark
13 mark

I have tried this one but its not working

/(?<!Total\:\s|Total\s|maximum\s|maximum\:\s)[\[|\(]?([0-9]{1,2})(\s|(?=marks|mark|mks|mk|m|\]))?(\]|marks|mark|mks|mk|m)[\]|\)]?/i

EDIT2 e.g '12 mark' should be returned only is its not "Total[:]\s+ 12 mark" or "maximum[:]\s+12 mark"

Answer 1

Try this: (?:\[?\b(?:Total|maximum):?\s?\d+\s?[^ ]+(*SKIP)(*FAIL))|(\d++\s?[^ )\]]*)

(Use ignore case.)

Explanation

Part 1

• (?:\[? Non capturing group that may have a [
• \b Boundary
• (?:Total|maximum) non capturing group matching either literal
• :?\s?\d+\s? Maybe a : maybe a space, some digits, maybe another space.
• [^ ]+ A bunch of non spaces.
• (*SKIP)(*FAIL))| Plot twist: Anything matching Part 1 FAILS

Part 2

• This is captured, for real.
• \d++\s? digits, maybe followed by a space.
• [^ )\]]* And maybe stuff that's not a space, ), or ].

---

The PHP should look something like this:

preg_match_all(
  '/(?:\[?\b(?:Total|maximum):?\s?\d+\s?[^ ]+(*SKIP)(*FAIL))|(\d++\s?[^ )\]]*)/i', 
  "YOUR STRING",
  $matches
);

print_r($matches[0]);
