Answer 1

There are number of way to filter array in PHP.

Using array_filter

$your_array = array(10,15,18,25,88,20);
$filtered = array_filter($your_array, create_function('$var', 'return $var >= 10 && $var <= 20;'));
var_export($filtered);

In action

If you want to change range start and range end without modifying create_function code:

$your_array = array(10,15,18,25,88,20);
$range_start = 10;
$range_end = 20;
$filtered = array_filter($your_array, create_function('$var', 'return $var >= '.$range_start.' && $var <= '.$range_end.';'));
var_export($filtered);

In action

$your_array = array(10,15,18,25,88,20);

Using foreach loop:

$filtered = array();
$range_start = 10;
$range_end = 20;
foreach ($your_array as $k=>$v) {
    if ($v >= $range_start && $v <= $range_end) {
        $filtered[$k] = $v;
    }
}
var_export($filtered);

In action

Or so if you don't need to create new array, but modify existing one:

$your_array = array(10,15,18,25,88,20);

$range_start = 10;
$range_end = 20;
foreach ($your_array as $k=>$v) {
        if (!($v >= $range_start && $v <= $range_end)) {
                unset($your_array[$k]);
        }
}
var_export($your_array);
