Parsing BBCode to HTML

[jonbach]

I can confirm the last post. This method does not work when part of a function, which is a big problem when integrating into some existing sites.

This works:

PHP Code:

$cwd = getcwd();
chdir("/mypath");
include("/mypath/global.php"); 
include("/mypath/includes/class_bbcode.php"); 
$bb_parser =& new vB_BbCodeParser($vbulletin, fetch_tag_list()); 
chdir($cwd);

function bb_convert_works($bb_parser, $text){
    $parsed_text = $bb_parser->do_parse($text); 
    return $parsed_text;
}

$text = "[url=http://www.google.com][b]Google[/b][/url]"; 
echo bb_convert_works($bb_parser, $text); 


This does NOT work:

PHP Code:

function bb_convert_doesnt_work($text){
    $cwd = getcwd();
    chdir("/mypath");
    include("/mypath/global.php"); 
    include("/mypath/includes/class_bbcode.php"); 
    $bb_parser =& new vB_BbCodeParser($vbulletin, fetch_tag_list()); 
    chdir($cwd);
    $parsed_text = $bb_parser->do_parse($text); 
    return $parsed_text;
}

$text = "[url=http://www.google.com][b]Google[/b][/url]"; 
echo bb_convert_doesnt_work($text); 


The errors I get when I try the second code are:

Warning: array_keys() [function.array-keys]: The first argument should be an array in [path]/includes/functions.php on line 4227

Warning: Invalid argument supplied for foreach() in [path]/includes/functions.php on line 4227

Fatal error: Call to a member function query_read_slave() on a non-object in /mypath/includes/functions.php on line 3189

I have plenty of experience in PHP, but I haven't encountered a problem like this before. I really would prefer to not have to hack this together by hard coding the conversion code everywhere I need it. Does anyone have any ideas on why it breaks when within a function?
