need help w/ php replacing taps

how to replace html/php code using php function. . .

I know that -- - -I use htmlspecialchars

 

but I would like the replace them with bbcode, such as . . .

 

please help. . .

so instead of <B></B> you want it to be replaced with .

 

you could use the str_replace() function. it goes like this:

$message = $_POST['message'];//replace <b> with [b] in the message field from the form.$message= str_replace("<b>","[b]",$message);$message= str_replace("</b>","[/b]",$message);

you can do that for every tag or you can do it using an array within the str_replace() function like this:

 

str_replace(array('<b>','</b>','<i>','</i>'),array('[b]','[/b]','[i]','[/i]'),$message);

i am not sure if this is what you want exactly, but there it is anyways.

thanks a lot, I got an idea now, but I don't know if I need to use a function or not. . .what a function would be like??function bbcode () {. . .}I've never writted any function by myself, only know php built in function.

You could use a function but i don't think that you would have to. You can just put that in your php script/s, enter all of the tags you want to replace and what you want to replace them with in the array and they will all be converted. is there anything you need?

function bbcode () {

}

The function wouild be something like this:

 

function bbcode($message){	str_replace(array('<b>','</b>','<i>','</i>'),array('[b]','[/b]','[i]','[/i]'),$message);	//add other operations you want to do here	return $message;}

And you would call it like this, assuming that you have the stuff to convert in $msg variable.

 

$msg = bbcode($msg);

That would replace the contents of the $msg variable with that created by the function.

 

Quite easy isn't it?

I got troubles with the tag!!

 

function bbcode($a) {

$a = nl2br(htmlspecialschars($a));

$a = str_replace (array ("[/url]", ""), array ("<a href=>", "</a>"), $a);

return $a;

}

 

its not working!!! help; please

if you run your code

$a = str_replace (array ("[url]", "[/url]"), array ("<a href=>", "</a>"), $a);

on test, then the output will be:
[.url=test.html]test</a>
(Ignore the dot in the thing, it's just to make sure this forum shows the url stuff instead of making it a link..)

Look at your code. It will replace with <a href=>. Two problems:
1. There is no

in your string! Look, only an , so no replace will be made.
2. Should any replace be made, how is your PHP going to know that it has to put the test.html inbetween the = and the > in your Anchor tag?

Easiest is just using some regex..

function bbcode($a) {$sRes=eregi_replace($a,"\[url=(.*?)\]","<a href=\"\1\">");return $a;}

( I don't know for sure but you might have to escape the escape slashes themselves as well for the PHP engine to pass them to the regex... in that case, (if it doesn't work like this), use this: eregi_replace($a,"\\" ,"<a href=\"\\1\">") )
