Answer 1

Try with preg_match :

$input = '300G';
preg_match('/(\d+)(\w)/', $input, $matches);

var_dump($matches);

Output:

array (size=3)
  0 => string '300G' (length=4)
  1 => string '300' (length=3)
  2 => string 'G' (length=1)

And extra:

list(, $digits, $letter) = $matches;

Answer 2

This code should do the trick.

$str = '300G';

preg_match("/(\d+)(.)/", $str, $matches);

$number = $matches[1];
$character = $matches[2];

echo $number; // 300
echo $character; // G

Answer 3

$input = '300G';
$number = substr($input, 0, -1);
$letter = substr($input, -1);

Answer 4

use a regular expression

   $regexp = "/([0-9]+)([A-Z]+)/";
   $string = "300G";

   preg_match($regexp, $string, $matches);

   print_r($matches);

$matches[1] = 300 $matches[2] = G

Answer 5

$pattern = '#([a-z]+)([\d]+)#i';
if (preg_match($pattern, $str, $matches)){
    $letters = $matches[1];
    $numbers = $matches[2];
}

Answer 6

Try this,

<?php
    $input = '300G';
    preg_match('/(\d+)(\w)/', $input, $matches);
    var_dump($matches);
?>
