Pop last char in a string

Question

I have this string: 13.23E. What I need is to cut the letter E (or any last letter) to obtain two vars, one with the number, on with the letter.

Example:

$var = "12345E";
print_r(removeLastLetter($var));

// OUTPUT
array(
  [0] => "12345",
  [1] => "E"
)

Any help?
Thanks.

Answer 1

function removeLastLetter($string) 
{
    $part1 = substr($string, 0, -1); // get chars upto last
    $part2 = substr($string, -1); // get last char

    return array($part1, $part2);
}

Output:

Array
(
    [0] => 12345
    [1] => E
)

Demo!
