Basic problem, matching numeric elements by recursive regularization

Digui function program function for recursive regular matching numbers

If the number is saved in the new array, the last array that returns all elements containing the number


$array =array (
"22",
"1234",
Array ("A",
Array ("AaB", "00000", "AAA", "222000", "3333000"),
"AA", "999", "AAAA"),
"D",
"567",
"33",
"DSF");
$FL _array=array ();
function Digui ($arr)
{
Global $FL _array;
foreach ($arr as $key = $value)
{
if (Is_array ($value))
{
Digui ($value);
}
}

$FL _array = Preg_grep ("/\d+/", $arr);

return $FL _array;

}

Print_r (Digui ($array));
?>

$array =array (  "triple",  "1234",  Array (    "a",    array ("AaB", "00000", "AAA", "222000", "3333000"),    "AA", "999", "AAAA"),  "D",  "567",  "",  "DSF"), function Digui ($arr) {   $FL _array = Array ();  foreach ($arr as $key = + $value) {    if (Is_array ($value)) {      $FL _array = Array_merge ($fl _array, Digui ($value)) ;    }  }  $FL _array = Array_merge ($fl _array, @preg_grep ("/\d+/", $arr));     return $FL _array;} Print_r (Digui ($array));

Array
(
[0] = 00000
[1] = 222000
[2] = 3333000
[3] = 999
[4] = 22
[5] = 1234
[6] = 567
[7] = 33
)

$result =array (), global $result, function Getnum ($arr) {global $result; foreach ($arr as $value) {if (Is_array ($value)) { Getnum ($value);} if (Is_numeric ($value)) {Array_push ($result, $value);}} return $result;} Print_r (Getnum ($array));

It seems like you can also
