note 98088 added to function.str-getcsv

Here is my (fully tested) implementation of str_getcsv for PHP < 5.3 that I submitted on a previous post. Hope someone finds it useful.

if (!function_exists('str_getcsv')) { 
    function str_getcsv($input, $delimiter = ',', $enclosure = '"', $escape = '\\', $eol = '\n') { 
        if (is_string($input) && !empty($input)) { 
            $output = array(); 
            $tmp    = preg_split("/".$eol."/",$input); 
            if (is_array($tmp) && !empty($tmp)) { 
                while (list($line_num, $line) = each($tmp)) { 
                    if (preg_match("/".$escape.$enclosure."/",$line)) {
                        while ($strlen = strlen($line)) { 
                            $pos_delimiter       = strpos($line,$delimiter); 
                            $pos_enclosure_start = strpos($line,$enclosure); 
                            if (
                                is_int($pos_delimiter) && is_int($pos_enclosure_start) 
                                && ($pos_enclosure_start < $pos_delimiter)
                                ) {
                                $enclosed_str = substr($line,1); 
                                $pos_enclosure_end = strpos($enclosed_str,$enclosure); 
                                $enclosed_str = substr($enclosed_str,0,$pos_enclosure_end); 
                                $output[$line_num][] = $enclosed_str; 
                                $offset = $pos_enclosure_end+3; 
                            } else {
                                if (empty($pos_delimiter) && empty($pos_enclosure_start)) {
                                    $output[$line_num][] = substr($line,0);
                                    $offset = strlen($line);
                                } else {
                                    $output[$line_num][] = substr($line,0,$pos_delimiter);

                                                ?$pos_enclosure_start
                                                :$pos_delimiter+1; 
                                } 
                            }

    }
