I think you are over thinking it but if a regex is really needed capture all the integers then implode them.
$string = "1, 2, 3, 4, 5, 6, 7, 8";
preg_match_all('/[0-9]+/', $string, $match);
echo implode("\n\n", $match[0]);
Exploding then imploding seems like an easier approach though:
$string = "1, 2, 3, 4, 5, 6, 7, 8";
echo implode("\n\n", explode(', ', $string));

Are you in a web browser?
Try this..Hope it will works..
The explode() function breaks a string into an array.
$string = "1, 2, 3, 4, 5, 6, 7, 8";
$arr=explode(',',$string);
foreach ($arr as $a) {
echo $a."<br/>";
}

Please try this example:
$string = "1, 2, 3, 4, 5, 6, 7, 8";
$data= explode(',' ,$string);
echo "<pre>".implode("\n",$data)."</pre>";

if you just want to show as your output you can use
$string = "1, 2, 3, 4, 5, 6, 7, 8";
$int = preg_replace('/[^0-9]+/', '<br /><br />', $string);
echo $int;
another approach (which i would use)
$string = "1, 2, 3, 4, 5, 6, 7, 8";
$int = explode(',', $string);
var_dump($int);
here all the integer value will be separated and can be use as you like

[^0-9] is more simply \D. <?php
$string = "1, 2, 3, 4, 5, 6, 7, 8";
$int = explode(", ",$string);
foreach ($int as $value) {
echo "$value <br>";
}
?>
Output
1
2
3
4
5
6
7
8

If you want PHP output only, then replace the second line of your code with the line below:
$int = preg_replace('/[^0-9]+/', "\n", $string);
Note the double quote for the second parameter.
But, if you want output in HTML only, use this:
$int = preg_replace('/[^0-9]+/', '<br />', $string);
Good luck.
