PHP - Remove characters and separate numbers

Does anyone know PHP code that would strip any characters from string except number. But if there is space between numbers it would separate them.

Example input:

$input = '28  -  200 mm';

Output:

$num1 = 28;
$num2 = 200;

Thank you!

You would have a better chance using Regex with your problem.

But here is quick a solution :

$string = "28 - 100 mm";
$arr = explode(" ",$string);
$numbers = array();
foreach($arr as $value)
{
    if(intval($value))
        $numbers[] = intval($value);
}

Which results in array(2) { [0]=> int(28) [1]=> int(100) }

<?php
   $str = '28  -  200 mm';
   $pattern = '#(?P<numbers>\d+)#';
   if(preg_match_all($pattern, $str, $matches)){
       foreach ($matches['numbers'] as $number) {
           echo $number;
       }
   }

Your basic regex would look like:

#\b(\d+)\b#
        ^^ word boundary
    ^^^ one or more digits

So something like:

preg_match_all('#\b(\d+)\b#', $your_string, $results);

And the results would be stored in the $results array, see the manual on preg_match_all.
