php Regex Question...

[phpSensei]

I am terrible at understanding, and writing regular expressions, and using preg_match(); .

 

I need some code that can detect"<TAG> string </END TAG>", and replaces the <TAG> and </Tag> with something of my own...

 

basically, this is for a ["b"][/"b"], and ["url"=""][/url] code I need for my forum....

Here's a quick example. You can find more by searching the forums for "bbcode".

 

<pre>
<?php
$string = '<TAG>stuff</TAG>';
echo preg_replace('#<([^>]+)>(.*?)</\1>#', '[b]$2[/b]', $string);
?>
</pre>

Even after reading through the manual?

 

Here's an explanation from Perl's YAPE::Regex::Explain:

NODE                    EXPLANATION

----------------------------------------------------------------------

  <                        '<'

----------------------------------------------------------------------

  (                        group and capture to \1:

----------------------------------------------------------------------

    [^>]+                    any character except: '>' (1 or more

                            times (matching the most amount

                            possible))

----------------------------------------------------------------------

  )                        end of \1

----------------------------------------------------------------------

  >                        '>'

----------------------------------------------------------------------

  (                        group and capture to \2:

----------------------------------------------------------------------

    .*?                      any character except \n (0 or more times

                            (matching the least amount possible))

----------------------------------------------------------------------

  )                        end of \2

----------------------------------------------------------------------

  </                      '</'

----------------------------------------------------------------------

  \1                      what was matched by capture \1

----------------------------------------------------------------------

  >                        '>'
