You just need to move the print outside of the foreach loop. This code will add the number from 1 to 10, 11 to 20 .. etc according to the input [which is $text]. And print all of them at the end.

<?php
$text   = "1*10
11*20
21*30
31*40
41*50";
$textAr = explode("
", str_replace("", "", $text));
$textAr = array_filter($textAr, 'trim');

foreach ($textAr as $line) {
    $pieces = explode("*", $line);
    list($first, $last) = array_pad(explode('*', $line, 2), 2, null);

    $add = 1;
    for ($i = $first; $i <= $last; $i += $add) {
        $array[] = array(
            'count' => $i
        );
    }


}

$codes = $array;
foreach ($codes as $code) {
    echo $code['count'];
    echo "<br>";
}
?>

Result :

1
