php数组跳过大于X的值[重复]

I have an array with values between 1-100. However, in case of an error, is there a way to make one final check just to be sure I skip/ignore values greater than 100 and the output is between 1-100?

</div>

This is where array_filter() comes in handy.

$lower_limit = 1;
$upper_limit = 100;

$array = array_filter(
    $array,
    function ($value) use ($lower_limit, $upper_limit) {
        return ($value >= $lower_limit && $value <= $upper_limit);
    }
);

Using array_filter is a way to it.

It will iterate through your array and filters it using the supplied function. In the end you'll get an array with only elements between 1 and 100.

$arr = array(
    1, 2, 99, 201,
);

$goodArr = array_filter($arr, function($value){
    return ($value >= 1 && $value <= 100);
});
