$array = array(1, 2, 3, 5, 1, 7, 15);
$b = [];
foreach ($array as $key) {
    array_push($b, $key);
}
print_r($b);

Андрей,

$array = array(1, 2, 3, 5, 1, 7, 15);
$b = [];
foreach ($array as $key) {
   $b[] = $key;
}
print_r($b);

jasonOk,
print_r([1, 2, 3, 5, 1, 7, 15]);

Андрей, $b[] = ... should be used instead (2x faster).
[]= works faster than invoking functions in PHP.

[Anton Mashletov]

Убрать return и инициализацию $b вывести перед циклом, а не внутри него.

print_r($array);
