You can use this function instead of urldecode()
您可以使用此函数代替 urldecode()
function utf8_urldecode($str) {
return html_entity_decode(preg_replace("/%u([0-9a-f]{3,4})/i", "&#x\1;", urldecode($str)), null, 'UTF-8');
}

htmlspecialchars(urldecode($str));

Rather than using escapeon the client-side, use encodeURIComponent. escapedoes notdo URI-encoding. (It does something similar, but different enough that you'll have trouble.) encodeURIComponentdoes standard URI-encoding. PHP should decode it for you automatically if you're sending the data in the normal way, e.g.:
而不是escape在客户端使用，使用encodeURIComponent. escape并没有做URI编码。（它做一些类似的事情，但足够不同，你会遇到麻烦。）encodeURIComponent做标准的 URI 编码。如果您以正常方式发送数据，PHP 应该自动为您解码，例如：
var word = "balaji's";
$.ajax({
url: "yoururl",
data: encodeURIComponent("word") + "=" + encodeURIComponent(word)
});
If you're not sending the data in the default "multipart form" form (e.g., you're overriding dataType), you'll have to decode it yourself via urldecode.
如果您没有以默认的“多部分形式”形式发送数据（例如，您要覆盖dataType），则您必须通过urldecode.

Consider the PHP functions, urldecode()or rawurldecode().
考虑 PHP 函数urldecode()或rawurldecode()。
One difference, it seems, is in the handling of + (plus signs).
一个区别似乎在于 +（加号）的处理。
You should make sure to test with strings containing plus signs to ensure you have chosen the correct function.
您应该确保使用包含加号的字符串进行测试，以确保您选择了正确的函数。
