javascript to php question

Keep in mind that this code will for for ANY html tag so you may want to code in some safeguards to prevent it. It uses the perl regular expression replace function built into php. More information on this function can be found at http://us2.php.net/manual/en/function.preg-replace.php
----------------------------------------------------------------------------------------------------
$str = replacetags("[b]this is some bold text[/b]
[linebreak]
[br]
[linebreak]
[i]This is some italic text[/i]");

echo($str);

function replacetags($str){
      $str=preg_replace('/\[linebreak\]/i','<br />',$str);
      $str=preg_replace('/\[(\w*)\]/i','<$1>',$str);
      $str=preg_replace('/\[\/(\w*)\]/i','</$1>',$str);
      return $str;
}

my example has colons...

[br] to <br />  
[b:]abc[:b] to <b>abc</b>  
[a: href="anything"]abc[:a]  to  <a href="anything">abc</a>

how do you add the colon into that??

I don't quite see the point in the colons but here is your text/example...


----------------------------------------------------------------------------------------------------
$str = replacetags('[br] to <br />  
[b:]abc[:b] to <b>abc</b>  
[a: href="anything"]abc[:a]  to  <a href="anything">abc</a>');

echo($str);

function replacetags($str){
      $str=preg_replace('/\[linebreak\]/i','<br />',$str);
      $str=preg_replace('/\[(\w*)\]/i','<$1>',$str);
      $str=preg_replace('/\[(\w*)\:([^\]]*)\]/i','<$1$2>',$str);
      $str=preg_replace('/\[\/(\w*)\]/i','</$1>',$str);
      return $str;
}
----------------------------------------------------------------------------------------------------

The only difference is [br] is getting switched to <br> and not <br /> which shouldn't really matter.

your example returns <br> to <b>abc<b> t<a href="anything">abc<a>...

the closing tags arent converting correctly. It still doesnt work.

my apologies I thought you were trying to convert bbcode which uses [/b] as a closing.

----------------------------------------------------------------------------------------------------
$str = replacetags('[br] to <br />  
[b:]abc[:b] to <b>abc</b>  
[a: href="anything"]abc[:a]  to  <a href="anything">abc</a>');

echo($str);

function replacetags($str){
     $str=preg_replace('/\[linebreak\]/i','<br />',$str);
     $str=preg_replace('/\[(\w*)\]/i','<$1>',$str);
     $str=preg_replace('/\[(\w*)\:([^\]]*)\]/i','<$1$2>',$str);
     $str=preg_replace('/\[:(\w*)\]/i','</$1>',$str);
     return $str;
}
----------------------------------------------------------------------------------------------------

basically we just changed the last line before return $str to check for :tag instead of /tag

closing tags still arent closed...

awesome
