I'm trying to make a BBCode parser, and so far I have it working well enough, but, well, not well enough.

For example, it can do this:
Bold
but it can't do this:
bold red
for some reason.

I'm using a preg_replace to match the BBCodes, but it doesn't work.

PHP Code:

$bbreplace = array (
"/(\[[Ii]\])(.+)(\[\/[Ii]\])/",
"/(\[[Bb]\])(.+)(\[\/[Bb]\])/",
"/(\[[Uu]\])(.+)(\[\/[Uu]\])/",
"/(\[[Ss]\])(.+)(\[\/[Ss]\])/",
"/(\[color=)(.+)(\])(.+)(\[\/color\])/",
"/(\[colour=)(.+)(\])(.+)(\[\/colour\])/",
"/(\[url=)(.+)(\])(.+)(\[\/url\])/",
"/(\[img\])(.+)(\[\/img\])/
");

$bbreplacements = array 
("<i>\\2</i>",
"<b>\\2</b>",
"<u>\\2</u>",
"<s>\\2</s>",
"<span style=\"color:\\2\">\\4</span>",
"<span style=\"color:\\2\">\\4</span>",
"<a href=\"\\2\">\\4</a>",
"<img src=\"\\2\" />
");
$string = "[color=red][b]bold red[/b][/color]";
$newReplyContent = preg_replace($bbreplace, $bbreplacements, $string); 


It will just echo it bold, but not red . Unfortunately, the above example works perfectly, but when I use it on my site, it suddenly craps out.

What is wrong with that code? I got it from the BBCode site and adapted it a bit, but that's it.

What does $newReplyContent come out like?

Well it usually ends up echoing just the last line of the string (I'm dealing with large strings)

If you look at the source it's something really messed up like

<span style="color:red]something the stringbold[/<span>

Something weird like that. This is from mobile so I can't get the full report on it, but it's something along those lines. It's just not replacing ALL of the tags, just SOME of them, where and when it likes to :|

Other information:
I am running the BBCode off inside a config.php file, which is included inside the file I am calling the preg_replace function (thread.php).

Once I removed the newlines in the last elements of the search and replaces arrays (from the last element), it worked.

(I had to upload as file, because for some reason I could not get it to display below)

Hmm, for some reason my computer can't download that... Can you maybe try Pastebin? Thanks

Great! That works amazingly! Thank you

(In case this thread is googled but the file is taken down, and somebody wants the answer, here is what the file contains: )

<?php


$bbreplace = array (
"/(\[[Ii]\])(.+)(\[\/[Ii]\])/",
"/(\[[Bb]\])(.+)(\[\/[Bb]\])/",
"/(\[[Uu]\])(.+)(\[\/[Uu]\])/",
"/(\[[Ss]\])(.+)(\[\/[Ss]\])/",
"/(\[color=)(.+)(\])(.+)(\[\/color\])/",
"/(\[colour=)(.+)(\])(.+)(\[\/colour\])/",
"/(\[url=)(.+)(\])(.+)(\[\/url\])/",
"/(\[img\])(.+)(\[\/img\])/");

$bbreplacements = array 
("<i>\\2</i>",
"<b>\\2</b>",
"<u>\\2</u>",
"<s>\\2</s>",
"<span style=\"color:\\2\">\\4</span>",
"<span style=\"color:\\2\">\\4</span>",
"<a href=\"\\2\">\\4</a>",
"<img src=\"\\2\" />");
$string = "[b][color=red]Bold Red[/color][/b]";
$newReplyContent = preg_replace($bbreplace, $bbreplacements, $string);  
echo htmlentities($newReplyContent);

I don't know why, but everytime I tried to paste that into here, it would break - Why would it work fine for you??

I put noparse tags around the code
