php - using regex to skip ahead all characters until a specific sequence of letters is found using negative lookahead -

I'm fine with basic regular expressions, but I have to show a few forward / back behind Poiss / Dag.

I'm trying to drag it by ID:

 [keyword stuff = otherstuff id = 123 morestuff = stuff] 

can be in unlimited quantity Before or after "luggage" I am using the Regox Coach which I have tried to help debug, but I'm not moving anymore ...

So far my The pass is:

  [[keyword (? :: id = ([0-9] +))? [^ \]] * \]  

takes care of any additional features after the id, but I can not understand how to ignore everything between the keyword and the id. I Know that I can not go to [^ id] * , I believe I need to use a negative lookout like this (?! Id) * But I think because it does not work beyond zero-width, it does not work either:

  \ [keyword [a-z0-9 =] * (?! Id) (?: Id = ([0-9] +))? [^ \]] * \]  

I was looking for examples for everything but I could not find any one. Or maybe I have it, but they have gone so far on my head. I do not know what they were.

Help! Thank you.

EDIT: It must also be matched with [keyword stuff = other staff], where ID = is not present at all, so I should have 1 or 0 on the ID # group. There are also other [otherkeywords id = 32] which I do not want to match. The document needs to match many of the documents [keyword id = 3] using preg_match_all.

No letterhead / back requirement:

  / \ [keyword (?: [^ \]] *? \ Bid = ([0- 9] +)) [^ \]] *? \] /  

'[^]] *]' added to check an actual tag end, may be unnecessary.

Edit: \ b is added as an ID, otherwise it may match [keywords - you do not want it-guid = 123123-132123-123 id = 123 ]

preg_match_all ("/ [[keyword (?: [^ \]] *? \ Bid = ([0-9] +))? [^ \]] *? \] / "," [Keyword content = other types of more content = stuff] "matches $); Var_dump (matches $); 'Array (2) {[0] = & gt; Array (1) {[0] = & gt; String (42) "[Keyword Content = Other Types of Content = Accessories]"} [1] = & gt; Array (1) {[0] = & gt; String (0) ""}} $ php -r 'var_dump (preg_match_all ("/ \ [keyword (?: [^ \]] *? \ Bid = ([0- 9] +))? [^ \] *? \] / "," [Keyword content = other object ID = 123 more stuff = stuff] ", $ matches), $ matches; 'Int (1) array (2) {[0] = & gt; Array (1) {[0] = & gt; String (49) "[keyword stuff = other object ID = 123 more stuff = stuff]"} [1] => Array (1) {[0] = & gt; String (3) "123"}}
