我的一个朋友正在使用一个 bb 脚本，它将普通文本回显到 bb 代码中。他给了我脚本，但似乎不明白如何让它工作。
这是脚本
define ("EMOTICONS_DIR", "img/smilies/");
function bb($text) {
$text = $poke1['status'];
$text = htmlspecialchars($text);
$text = trim($text);
if (!function_exists('escape')) {
function escape($s) {
global $text;
$text = strip_tags($text);
$code = $s[1];
$code = htmlspecialchars($code);
$code = str_replace("[", "[", $code);
$code = str_replace("]", "]", $code);
return '<pre><code>'.$code.'</code></pre>';
}
}
$pattern = '#\b(([\w-]+://?|www[.])[^\s()<>]+(?:\([\w\d]+\)|([^[:punct:]\s]|/)))#';
$callback = create_function('$matches', '
$url = array_shift($matches);
$text = preg_replace("/^www./", "", $text);
$text = $url;
if (preg_match("/\[/i", $url) || preg_match("/\]/i", $url)) {
return($url);
}else{
return sprintf(\'<a href="%s" target="_blank" rel="nofollow">%s</a>\', $url, $text);
}
');
$text = preg_replace_callback($pattern, $callback, $text);
$text = preg_replace_callback('/\[code\](.*?)\[\/code\]/ms', "escape", $text);

}
所以我在顶部的 $text 中输入文本 [b] hello [/b] 并且在脚本之后什么也没有得到我像这样回显它
echo bb($text);
但是我没有打印出来......如果我只是打印出 $text = $poke1['status']; 它会打印出来，但只有普通文本，例如 [b] hello [/b]
