Question: I'm kinda of new in android. How can i send an email automatically without a contact chooser. 
I write a list of e-mails in edittext and an message and then i want to send to every email address. 
How can i do that?

Answer: 
Is `array_filter` is the method your looking for. I guess there are enough ways to do this :)

```
$array = [0, 15, 60, 120, 2200];
$number = 15;
$filtered = array_filter($array, function($element) use ($number) {
   return ($element <= $number);
});
// $filtered = [0, 15];

$max = max($filtered); //15

```
This can never be true:

```
if ($val>= $number && $val < $number)

```

I would try:

```
$highest = 0;
foreach ($arr as $val) {
    if($val <= $number){
       if($val >= $highest){
           $highest= $val;
       }
    }
}
return $highest;

```
