1372行 if (!preg_match("/^[\w-:]+$/", $tag)) { 错误

[wengxianxun]

WARNING: preg_match(): Compilation failed: invalid range in character class at offset 4 in /home/ymserver/vhost/ios_wall_ads/spider/protected/simplehtmldom/simple_html_dom.php on line 1372

提示这个错误，怎么解决呢？

PHP 7.3 and above you need to escape hyphen to make it work.
