I'm working on a BBCode Parser for my blog, so I can style it a little and post code snippets. It seems to be working so far, except that it's wrapping lines of the output when it shouldn't. I think its a CSS problem because the actual output (view source) is all on one line, but I'm unsure how to fix this. I have overflow set to auto, but even if i set it to  scroll it seems to not be working as intended.

Below is the code for the function and the example usage producing the erroneous output. Attached is an image showing how the output is being wrapped.


 Returns the given string with BBCodes replaced by HTML and PHP tags highlighting syntax
function bbmarkup($input) {
	$BBCodes = 		array('[B]'		 ,'[/B]'		 ,'[I]','[/I]','[U]','[/U]');
	$HTMLCodes = 	array('<strong>','</strong>','<i>','</i>','<u>','</u>');
	//*/ Find and replace URL tags
	$URLRegEx = 	 '#\[url(=(.*?))?\](.*?)\[\/url\]#i';
	$URLFind = array();
	$URLReplace = array();

	//*/ Build find and replace arrays for links
	if( preg_match_all($URLRegEx,$input,$matches) ) {
		foreach( $matches[0] as $k => $v ) {
			$URLFind[$k] = $v;
		foreach( $matches[3] as $k => $v ) {
			if( empty($matches[2][$k]) )
				$url = $v;
				$url = $matches[2][$k];
			$URLReplace[$k] = '<a href="'.$url.'" target="_blank">'.$v.'</a>';

	//*/ Find and Highlight code within PHP tags
	$PHPfind = array();
	$PHPreplace = array();
	$pattern = '#\[PHP](.+?)\[\/PHP\]#is';

	//*/ Set up replace array for PHP tags
	if( preg_match_all($pattern,$input,$matches) ) {
		foreach( $matches[1] as $k => $v ) {
			$PHPreplace[$k] = '<div class="code">'.highlight_string($v,TRUE).'</div>';

	//*/ Filter BBCodes and replace with HTMLcodes
	$output = str_ireplace($BBCodes,$HTMLCodes,$input);
	$output = nl2br($output);
	$output = str_replace($URLFind,$URLReplace,$output);

	//*/ Set up replace array for PHP tags (post BB filtering, so the BB tags don't get changed when IN php code)
	if( preg_match_all($pattern,$output,$matches) ) {
		foreach( $matches[0] as $k => $v ) {
			$PHPfind[$k] = $v;

	//*// Replace PHP tags + containing strings with highlighted version
	$output = str_replace($PHPfind,$PHPreplace,$output);
	return $output;

//*/ Example Usage
$str = <<<'STR'
Link with text:[url=]Google![/url]

class Database {
	const DBHOST = 'HOST';
	private $lastError;
	private $db;
	public function __construct() {
		$this->db = new mysqli(self::DBHOST,self::DBUSER,self::DBPASS,self::DBNAME);
	public function error() {
		return $this->lastError;

[php] <?php
		// Build Query
		$sql = "SELECT $columns FROM `$table` WHERE ";
		foreach( $where as $k => $v ) {
			$sql .= "`$k` = '$v' AND ";
		$sql = substr($sql,0,-5);
		$sql .= $limit;
		// Run query and return results
		$result = $this->db->query($sql);
		if( !$result ) {
			$this->lastError = 'Query Failed: ('.$this->db->errno.') '.$this->db->error.'<br>'.$sql;
			return FALSE;

		<title>Highlight Test</title>
		<style type="text/css">
		div.code {
			padding: 5px;
			overflow: auto;
			width: 500px;
			max-height: 300px;
			border: 3px ridge #BBBBBB;
			background-color: #DDDDDD;
			margin: 10px 25px 10px 50px;
<?php echo bbmarkup($str); ?>
