How can I remove multiple 'BAD' values from an array

Suppose $arr is this:

Array
(
[0] => 43
[1] => 120
[2] => 5
[3] => 5465
[4] => 397
)

and I want any values between 111-5000 to be removed. If done correctly, my array would be:

Array
(
[0] => 43
[1] => 5
[2] => 5465

)

Hopefully the keys update on their own. Any ideas on how to accomplish that?

You can achieve using the following logic too.

foreach ($array as $key => $value) {
    if($value >= 111 && $value <= 5000) {
        unset($array[$key]);
    }
}

But what John mentioned in the above post is the optimal solution. It's quicker than this logic.

Thanks!

Use array_filter() with a custom callback that removes unwanted values:

$array = array(43,120,5,5465,397);
$filtered = array_filter($array, function($val){
    return ($val < 111 || $val > 5000);
});
print_r($filtered); // Array ( [0] => 43 [2] => 5 [3] => 5465 )

See it in action

You can also do

$array = array(43,120,5,5465,397);
$filtered = array_filter($array, function($val){
    return !($val > 111 && $val < 5000);
});
