PHP character encoding problem: GB2312 VS UTF-8 solution_PHP tutorial

Look at the code:

Copy the code The code is as follows:

$string1 = "i am a phper";
$string2 = "This website is a home for scripts";
print_r(str_split($string1));
echo "
";
print_r(str_split( $string2,4));
?>

The test results came out as I expected——Chinese Garbled characters

Why? Why? Why? Why? What is garbled code? What is garbled code? Explain to me, what is the garbled code of %&!

Because there are no garbled characters in English but only Chinese garbled characters, I first thought about the encoding problem, and then suddenly remembered that the encoding of UTF-8 is that UTF-8 requires 3 bytes. Let’s treat it like a dead horse!

So print_r(str_split($string2,4)); the 4 in this sentence was replaced by 6, so - look at the result

Similarly, you can also try changing the UTF-8 of the encoded charset to GB2312. Because Unicode encoding requires 2 bytes, Gb2312 encoding can save 1/3 of the space than UTF-8. But if you want to be compatible with other languages ​​such as Traditional Chinese, Korean, and Japanese, you need to use UTF-8.
