TO SPLIT string into ARRAY its best to use

Use the str_split function.

$array = str_split( 'testing');

Answer 3

$string = "TEST";

echo $string[0];  // This will display T

There is no need to explode it

As indicated by your error, explode requires a delimiter to split the string. Use str_split instead:

$arr = str_split('testing');

Output

Array
(
    [0] => t
    [1] => e
    [2] => s
    [3] => t
    [4] => i
    [5] => n
    [6] => g
)
