Answer

You are trying to get all “bytes” of the unicode string. You need to use mb_strlen() to get the real length of the characters.

Then, you need to use mb_substr() to get the right character.

$Text = '{"text":"سلام"}';
for($i = 0; $i < mb_strlen($Text); $i++) {
    echo mb_ord(mb_substr($Text,$i, 1)), "<br>";
}

Output :

123
34
116
101
120
116
34
58
34
1587
1604
1575
1605
34
125
