Replace everithing that is not a number:

  $numbers = preg_replace( '/[^\d\.]/', '', $input );

or if you will have decimal:

$numbers = preg_replace ( '#\D*?(\d+(\.\d+)?)\D*#', '$1', $input );

Replace everything that is NOT a number with an empty string. 

  $numbers = preg_replace('/[^0-9]*/','',$x);
