I've tried [0] but have been told it's wrong?

Answer 2

have you tried for loop?

Answer 3

$myString = "Hello";
$first = $myString[0]; // This actually gets the first Byte not necessarily the character
$first = subset($myString, 0, 1) // Again gets the first Byte
These may have issues when the the encoding character type, like UTF-8, is multibyte.
So use:
$first = mb_substr($myString, 0, 1, 'utf-8');
