Matching BBCode content and attribute via regex

I use the PECL BBCode class in an older project to manage BBCodes, which works very well. For some special cases, it doesn't suffice, because I need to run a function over input. So I want to do this with regex before the PECL thing is runnning.

I want to match the [member]-tag with as well as without attribute:

[member]Donald Duck[/member]
[member=Dr. Donald Duck]Donald Duck[/member]

I can match them this way:

\[member\](.+?)\[\/member\]
\[member=(.+?)\](.+?)\[\/member\]

How can I do this in one step? I made the = optional with ? but it doesn't match both. Thank you for your support.

You should add = to the optional group:

\[member(=.*?)?](.+?)\[\/member]
        ^^^^^^^

See the regex demo

Details

  • \[member - a literal [member substring
  • (=.*?)? - Group 1: an optional sequence of = and then any 0+ chars other than line break chars, as few as possible
  • ] - a ] char (no need to escape it)
  • (.+?) - Group 2: one or more chars other than line break chars, as few as possible
  • \[\/member] - a literal [/member] substring.
