Trim and foreach

[Anon]

I have splited some text and got a bunch of numbers, the prob. is that the numbers can have "spaces" next to them. ' 5' and so on can I somehow use foreach and trim these numbers?

Thanks.

$del = "|";
$string = " 1| 2| 3| 4| 5";
$arr = split("|",$string);
for($i=0$ < count($string);$i++) {$arr[$i]=trim($arr[$i]);}

// both are same
reset ($arr);
while (list($key, $value) = each ($arr)) {
$arr[$key] = trim($value);
}

<?php
$separator = ',';
$string = '3, 5, 7, 9, 10';

$string = explode($separator,$string);
foreach ($string as $number) {
$number = trim($number);
echo "$number<br />";
}
?>

This will print:
3
5
7
9
10
