PHP extract all whole numbers into an array

I have following string: 

15 asdas 26 dasda 354 dasd 1

and all that i want is to extract all numbers from it into an array, so it will looks like this:

array(4) {
  [0]=>
  string(2) "15"
  [1]=>
  string(2) "26"
  [2]=>
  string(3) "354"
  [3]=>
  string(1) "1"
}

Is there a way in PHP to achieve it?

See this Demo

Solution 1 :

This solution use is_numeric function :

print_r(array_filter(split(" ", "15 asdas 26 dasda 354 dasd 1"),"is_numeric"));

Solution 2 :

This solution use your own function :

function is_number($var) { return !(0 == intval($var)); }
print_r(array_filter(split(" ", "15 asdas 26 dasda 354 dasd 1"),"is_number"));

Solution 3 :

To 5.3.0 and more, this solution use preg_split function :

print_r(array_filter(preg_split(" ", "15 asdas 26 dasda 354 dasd 1"),"is_numeric"));

$str = '15 asdas 26 dasda 354 dasd 1';
preg_match_all('/\d+/', $str, $matches);
print_r($matches);

You can use preg_match_all():

$string = '15 asdas 26 dasda 354 dasd 1';
preg_match_all('/\b(\d+)\b/', $string, $numbers);

var_dump($numbers[1]);
