Question

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

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

Answer 1

They produce different outputs because you provided different inputs, i.e. 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), i.e. 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.
