js/php encodeURI_PHP tutorial

The

encodeURI() function can encode a string as a URI, and the characters will be replaced by hexadecimal escape sequences.
The decodeURI() function can decode the URI encoded by the encodeURI() function.

The characters after encodeURI() of js are generally encoded in utf-8. If the server-side encoding is a different encoding, iconv conversion is required.
$a = urlencode(iconv("gb2312", "UTF-8", "Movie")); //Equivalent to javascript encodeURI("Movie");
echo $ a;
$b = iconv("utf-8","gb2312",urldecode("%E7%94%B5%E5%BD%B1")); //Equivalent to javascript decodeURI("%E7% 94%B5%E5%BD%B1");
echo $b;
