Trying to change '['

[php_joe]

I'm editing a bbs program I have and I'm having problems changing the BBCode into HTML.

 

I tried:

$message = str_replace('[b]', '<b>', $message);

which didn't work.

 

I tried:

$message = str_replace('[', '<', $message);

which also didn't work.

 

Why can't I change '['?

I think you have it backwards

 

Change this:

$message = str_replace('[b]', '<b>', $message);

 

To

$message = str_replace('<b>', '[b]', $message);

 

<a href="http://us2.php.net/str_replace">str_replace</a>

 

EDIT: If that doesn't work, try this.

 

$message = preg_replace('[b]','<b>', $message);

[php_joe]

Actually, I'm trying to change [b] into <b>

 

But, for some reason, when I tried

$clean_message = str_replace('[b]', '<b>', $message);

by itself it works, but when I put

$clean_message = str_replace('[b]', '<b>', $message);
$clean_message = str_replace('[/b]', '</b>', $message);

In, only the second one works.

[pocobueno1388]

Try giving your variable different names? And don't you mean to put $clean_message in the second one? If you don't you will get two strings, one stripping the and leaving the and vise versa.

 

$clean = str_replace('[b]', '<b>', $message);
$clean_message = str_replace('[/b]', '</b>', $clean);

 

Try that. I am just kinda playing around with it...if this doesn't work I will actually go into my FTP and try working with it.

 

Did you try the preg_replace() function I suggested in my last post?

[wildteen88]

Use arrays instead of multiple instances of str_replace, example:

 

<?php

$msg = "Hello [b]world[/b]! [u][i]Ohhhh[/i][/u]!";

$bbcode = array( '[b]', '[/b]',
                 '[i]', '[/i]',
                 '[u]', '[/u]' );

$html = array( '<b>', '</b>',
               '<i>', '</i>',
               '<u>', '</u>' );

$msg = str_replace($bbcode, $html, $msg);

echo $msg;

?>

 

However whne doing bbcodes I prefer to use regex. regex is more powerful allowing you to do more advanced bbcodes

Thanks guys, using multiple variable names works.

 

I have not tried the preg_replace or array yet, but I will.

I would definitely go with wildteen88 advice if you have multiple tags you are trying to do it with.

I would definitely go with wildteen88 advice if you have multiple tags you are trying to do it with.

if you have multiple tags, just add single str_replaces, and:

I think you have it backwards

 

Change this:

$message = str_replace('[b]', '<b>', $message);

 

To

$message = str_replace('<b>', '[b]', $message);

 

<a href="http://us2.php.net/str_replace">str_replace</a>

 

EDIT: If that doesn't work, try this.

 

$message = preg_replace('[b]','<b>', $message);

This:

$message = str_replace('[b]', '<b>', $message);

is actually correct.

ted_chou12 - Would it not be easier to use the array and replace every single tag in one go?

 

And yeah, I figured that I was the one who actually had it backwards soon after I posted that xP

[ted_chou12]

yeah, array does work here, however, special tags such as link would require the work done separately.

That's why I mentioned to do regex with advanced tags such as link-title str_replace is just too basic. You can do it on swell swop with regex. However reqex does take time to get used to. It tool me a few months to get used to it.

I've been messing with this all day. I think that there must be some kind of conflict with the rest of the code, because it's just not behaving right.

wildteen, does this work? because I am having some trouble with bb codes, maybe i can use this.

Thank you very much for this function. I hope I can get it to work!

[wildteen88]

To get it to work you just call the function bbcode_format and pass the string with your bbcodes in as the first parameter, example:
[code=php:0]<?php

// place bbcode parser code snippet here

$msg = "[b]Hello world![/b] Umm [u]BBCODES[/u]

[url=http://www.google.com]google.com[/url] <-- Ohh! a link";

$msg = bbcode_format($msg);

echo nl2br($msg);

?>

[php_joe]

The function worked great, thank you very much!

 

I was able to cut out the second function by adding

to the first one. I also added >>> <s> to the array.
