PHP common URL Processing function Summary, Phpurl function

This paper summarizes several parsing functions of URL encoding in PHP, such as Parse_url, Rawurldecode, Rawurlencode, UrlDecode, UrlEncode. Share it for everyone's reference. The specific usage is as follows:

The following is an introduction and an example: Parse_url ($str URL);

Convert URL to array: Print_r (Parse_url ("www.jb51.net")); Resolves the URL and outputs the returned array, and the URL-specific format string is restored to a normal string.

Syntax: string rawurldecode (String str);

return value: String

Function type: Encoding processing

Description: This function decodes the string, from the URL of the special format of the string to the ordinary string, the detailed encoding and decoding information and specification file can refer to RFC 1738, the code is as follows:
Copy the Code code as follows: Echo rawurldecode (' Foo%20bar%40baz '); Output Foo Bar@baz
String Rawurlencode (String str)
Returns a string, in addition to-_, in this string. All non-alphanumeric characters will be replaced with a percent (%) followed by a two-digit hexadecimal number, which is the encoding described in RFC 1738 to protect the literal character from being interpreted as a special URL delimiter, while protecting the URL format from transmitting media, like some messaging systems, Use character conversions when confusing, for example, if you want to include a password in the FTP URL:

Copy the Code code as follows:
$str = "http://www.bkjia.com"; Defining strings
$result =rawurlencode ($STR); Encodes the specified string
echo $result;
/*
UrlDecode ()
URL decoding
*///output result
$str = "Http%3a%2f%2fwww.jb51.net";
$result =urldecode ($STR);
echo $result;
/*
UrlEncode ()
URL encoding
*/
$str = "http://www.bkjia.com"; Defining strings
$result =urlencode ($STR); Encodes the specified string
echo $result; Output results
