问题
I'm attempting to make something like shortcodes in WordPress, and I'm looking for a regex that will take something like [title:This is a title] and turn it to just This is a title.
It would also be useful if someone could suggest a way to take something like [code:some code] and turn that into an array in the form of
array(
[0] => 'code'
[1] => 'some code')
or
array(
'code' => 'some code'
I've tried a few different regexes I've found here and there, but none of them seem to work.
Thanks
回答1:
preg_replace('/\[.*?:(.*?)\]/', '$1', $str);
CodePad.
If you wanted to capture the text before the colon, simply wrap it in parenthesis and it will become capturing group 1.
Update
I'm looking to use
preg_matchinstead ofpreg_replace
You'd want to use preg_match_all() to get all matches.
preg_match_all('/\[(.*?):(.*?)\]/', $str, $matches);
Ideone.
Alternatively, you could give them named capturing groups.
preg_match_all('/\[(?P<identifier>.*?):(?<body>.*?)\]/', $str, $matches);
Ideone.
