How to adjust preg_replace after PHP7.0 abandons it

高洛峰 2017-05-16 13:09:06

$options = Typecho_Widget::widget('Widget_Options');
$sUrl = str_ireplace('/', '\/', rtrim($options->siteUrl, '/'));
$preg = '#(<a .*?href=")(?!' . $sUrl . ')([^"]+)"(.*?<\/a>)#ise';
$text = preg_replace($preg, "stripslashes('$1') . '$options->siteUrl' . 'go.html?url=' . base64_encode('$2') . '\" target=\"_blank\ "' . stripslashes('$3')", $text);

After the code was put into PHP7.0, an error was reported. According to the prompts, I learned that preg_replace was abandoned and had to be replaced by preg_replace_callback. How to do it?

It’s not that preg_replace is abandoned, it’s the /e modifier that is abandoned.

I think it should probably be changed like this

preg_replace_callback($preg,
    function ($matches) {
        return stripslashes($matches[1]).$options->siteUrl.'go.html?url='.base64_encode($matches[2]).'\" target=\"_blank\"'.stripslashes($matches[3]);
    });
