在我的 CodeIgniter 应用程序中,我收到一组应该签入的学生录取号码。
入场号码可通过
$ad_no = $this->input->post('adn_no');
访问,可能如下所示:
array(5) {
[0]=> string(5) "11784"
[1]=> string(5) "11837"
[2]=> string(5) "11775"
[3]=> string(5) "11937"
[4]=> string(5) "12061"
}
我尝试用这些数字查询数据库,但结果仅显示第一个学生的结果。
我的代码:
foreach ($ad_no as $key => $id) {
$this->db->where_in('ad_no', $id);
$query = $this->db->get('duration');
$r = $query->result_array();
$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(
'ad_no' => $ad_no[$key],
'tot_hr' => $dur
);
}
$reslt = $this->Daily_temp_model->duration($durs);
在 foreach 循环中使用数组推送
$result=[];
foreach($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(
'ad_no' => $ad_no[$key],
'tot_hr' => $dur
);
}
$reslt = $this->Daily_temp_model->duration($durs);
使用 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";
}
?>
