Why use the UrlEncode () function for URL encoding

UrlEncode is to encode a special part of the URL. Urldecoder is the decoding of special parts.

Because when string data is passed to the Web server as a URL, spaces and special characters are not allowed in the string.

For example, when you want to pass the string data Name=lisi&wangwu here Lisi&wangwu is a string but the server will only recognize Lisi

So we're going to use UrlEncode to encode this string.

So here's the problem!!! I'm particularly interested in getting multiple values of the same parameter with the Get method

The NAME=LISI&WANGWU is represented by two values------->>>> here are two ways of saying

1) UrlEncode encode and then decode with UrlDecode you can get $name=$_get[' Name]=lisi&wangwu

Two or more values of the name parameter can be obtained with explode (' & ', $name)

2) It is also possible to pass the $url= ' Www.baidu.com?name=lisi&name=wangwu ';

$name =$_sever[' uery_string ') so you can get the URL suffix name=lisi&name=wangwu ';

Then still get the array $name=explode (' & ', $name);

The last step is to intercept the string $name0=substr ($name [0],5)//name= with a length of 5

$name 0=substr ($name [1],5]

$name 0=substr ($name [2],5]
