Answer 1

using array push in foreach loop
$result=[];
foreach($ad_no as $key => $id) {
$this->db->where_in('ad_no', $id);
$query = $this-> db-> get('duration');
$r = $query-> result_array();
array_push($result, $r);
$dur = $r[0]['tot_hr'];
$start = explode(':', $dur);
$end = explode(':', $tm);
$total_hours = $start[0] - $end[0];
$total_hours1 = $start[1] - $end[1];
$mins = abs($total_hours1);
$dur = $total_hours.":".$mins;
$durs[$key] =
array(

using in_array
<?php
$a = array('1.10', 12.4, 1.13);
if (in_array('12.4', $a, true)) {
echo "'12.4' found with strict check\n";
}
if (in_array(1.13, $a, true)) {
echo "1.13 found with strict check\n";
}
?>
