RegEx如何将方括号标签与中间的管道相匹配？

Question

preg_match_all("[[Train]]<p />[[Plane]]<p />[[Crane Sane]]<p />[[Slain (derp)|Slained]]",$regex,$out);

I want to just extract: -

[[Slain (derp)|Slained]]

This is what I have so far: -

$regex = "/\[\[.+?\\|.+?\]\]/";

Answer 1

Try:

$regex = "/(\[\[[^\\]]+?\\|[^\\]]+?\]\])/";
preg_match($regex,"[[Train]]<p />[[Plane]]<p />[[Crane Sane]]<p />[[Slain (derp)|Slained]]",$out);
print_r($out[1]);
