我正在尝试从字符串中删除LEFT-TO-RIGHT-MARK(\ u200e)和RIGHT-TO-LEFT-MARK(\ u200f)，然后再将其编码为JSON.以下两种似乎都不起作用:

I'm trying to remove LEFT-TO-RIGHT-MARK (\u200e) and RIGHT-TO-LEFT-MARK (\u200f) from a string before encoding it as JSON. Neither of the following seems to work:

$s = mb_ereg_replace("\u200e", '', $s);
$s = preg_replace("#\u200e#u", '', $s);
$s = preg_replace("#\u200e#", '', $s);
