Question

在代码点火器中一组学生详细信息检查前 - 每个循环，学生通过学生入学编号的基础获取

我的录取号码在 $ ad_no = $ this-＆gt; input-＆gt; post（'adn_no'）; ： -

array（5）{[0] =＆gt; string（5）“11784”[1] =＆gt; string（5）“11837”[2] =＆gt; string（5）“11775”[3] =＆gt; string（5）“11937”[4] =＆gt; string（5）“12061”}

我尝试选择这些录取号码的学生，但结果只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);

Answer 1

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);

Answer 2

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";
}
?>

如何在codeigniter中的where条件中检查数组？
