json_encode 。您只需以正确的方式使用它：

json_encode will work. You just have to use it the right way:

<a onclick="javascript:window.location.href=<?php echo htmlspecialchars(json_encode($url)); ?>">

这将会起作用，因为 json_encode 已经返回带引号的JavaScript表达式。需要 htmlspecialchars 来转义可能的HTML元字符。

This will work since json_encode already returns an JavaScript expression with quotes. And htmlspecialchars is needed to escape possible HTML meta characters.
