使用utf8_encode（）的字符串的php UTF-8编码给出与结果相同的字符串

Question

I am using this utf8_encode() function in php (using the online editor http://www.writephponline.com/). The problem is that I am getting the same string as a result. Am I doing something wrong... very very new to php. Looking for some guidance with respect to what is the correct result.

Example:

echo utf8_encode("a6ab35d3-905b-4d1e-a967-169c1aa2dd56d337e8bd-d6ae-4f3b-a4b6-0980dcbeb632");

Result is a6ab35d3-905b-4d1e-a967-169c1aa2dd56d337e8bd-d6ae-4f3b-a4b6-0980dcbeb632

Answer 1

All of the characters in your string are the same in utf8 as in ASCII. Utf-8 is a variable-length encoding that stores the same values as ASCII for character codes 32 - 127.

Try adding some accented characters to your test string.
