Question

I have an HTML form that sends 索索索 using post to my PHP file.

I tried strlen on it, but it gives me 24 instead of 3 (?!)…and this then breaks my for loop:

$in=$_POST['inn'];
$length=strlen($in)
for ($i=0; $i<$length; $i++) {
$cleanchar=$in[$i];
}

I want cleanchar as an individual character, like if only one character had been sent down with the POST.

How can I separate each character using PHP?

Answer 1

Try using mb_strlen for multi-byte characters operations:

echo mb_strlen('索索索', 'utf-8'); // or omit second parameter or change to your encoding

From documentation:

Returns the number of characters in string str having character encoding encoding. A multi-byte character is counted as 1.
