Why is the array printed correctly, and the array element with a crooked encoding?

Question

PHP

Simple question.
Code:
print_r($arr[$i]);
Result prntscr.com/j44yxx
Code: Result prntscr.com/j44zoc M?
print_r($arr[$i][2]);

Answer 1

In the first option, you are accessing the $i-th element of the array, and in the second, you are accessing the 3rd character in this element. If you want to get exactly the element in the string, then use this:

$str="строка";
$chrArray=preg_split("//u", $str, -1, PREG_SPLIT_NO_EMPTY);
echo $chrArray[2];
