explode the price sign & the number

how can i explode the $123 or USD123 or CAD$123 or 元123 dynamically into 

array [0] = "$"
array [1] = 123

?

$keywords = preg_split("/[^0-9]/", "$123");

The above is my testing code, but i can't get $ in array[0], any idea?

thanks

You can use the preg_match with following regex

preg_match('/([^0-9]*)([0-9\.]*)(.*)?/', '$20.99USD', $match);
var_dump($match);

The above will produce 

Array
(
    [0] => $20.99USD
    [1] => $
    [2] => 20.99
    [3] => USD
)

It can parse $, 20.99, USD as separate index in an array

Try this it would work for all.

$str = 'CAD$123';
$num = filter_var($str, FILTER_SANITIZE_NUMBER_INT);
$curr = explode($num,$str);

echo 'Your currency is '.$curr[0].' and number is '.$num;

you can use this

$txt='$123';

  $re1='(\\$)'; # Any Single Character 1
  $re2='(\\d+)';    # Integer Number 1

  if ($c=preg_match_all ("/".$re1.$re2."/is", $txt, $matches))
  {
      $c1=$matches[1][0];
      $int1=$matches[2][0];
      print "($c1) ($int1) \n";
  }

$string = '$123';

$string = preg_match('/^(\D+)(\d+)$/', $string, $match);

echo $match[1]; // $
echo $match[2]; // 123

Breakdown:

^(\D+) match 1 or more non digit at beggining of string

(\d+)$ match 1 or more digits until end of string
