网址编码PHP

Question

Hey guys, I have question about urlencode and rawurlencode...

I tested them out and they produce different result like firefox & some online encoders...

Example;

Firefox & encoders

 ä = %C3%A4 ß = %C3%9F 

PHP rawurlencode & urlencode

ß = %DF

ä = %E4

Anyone got some idea except hard-coding and replacing?

Cheers

Answer 1

They produce different outputs because you provided different inputs, ie different character encodings: Firefox uses UTF-8 and your PHP script uses Windows-1252 . Although in both character sets the characters are at the same position ( ß =0xDF, ä =0xE4), ie the have the same code point, they encode that code point differently:

 CP   | UTF-8  | Windows-1252
------+--------+--------------
 0xDF | 0xC39F |         0xDF
 0xE4 | 0xC3A4 |         0xE4

Use the same character encoding (preferably UTF-8) and you'll get the same result.

Answer 2

maybe base64 encode, and use in post, to not make visitors afraid of this URL's? Arsen
