Question

我有一个数组变量$ data，如下所示：

$data = array (
'deptIDid' =>array(
    'userid' =>array(
        '12:00' => array(
            'bookname'= 'Chemistry',
            'return'= 'false'
            )

        '12:01' => array(),
        '12:02' => array(),
        '12:03' => array(),
        '12:04' => array(),
        '12:05' => array(),
        '12:06' => array(),
        '12:07' => array(
            'bookname'= ''
            'return'= 'true'
        ),
        '12:08' => array(
            'bookname'= 'Math',
            'return'= 'false'
        ),
        '12:09' => array(),
        '12:10' => array(),
        '12:11' => array(),
        '12:12' => array(),
    ),
  )
)

逻辑是用户在部门库中借了一本书。在时间数组中，有两个元素userid和return。我需要做的是时间数组没有值。它应该添加一个类似于早期的值，直到return值变为true。输出应为：

 $data = array (
'deptIDid' =>array(
    'userid' =>array(
        '12:00' => array(
            'bookname'=> 'Chemistry',
            'return'=> 'false'
            )

        '12:01' => array(
            'bookname'=> 'Chemistry',
            'return'=> 'false'
            ),
        '12:02' => array(
            'bookname'=> 'Chemistry',
            'return'=> 'false'),
        '12:03' => array(
            'bookname'=> 'Chemistry',
            'return'=> 'false'),
        '12:04' => array(
            'bookname'=> 'Chemistry',
            'return'=> 'false'),
        '12:05' => array(
            'bookname'=> 'Chemistry',
            'return'=> 'false'),
        '12:06' => array(
            'bookname'=> 'Chemistry',
            'return'=> 'false'),
        '12:07' => array(
            'bookname'=> 'Chemistry'
            'return'=> 'true'
        ),
        '12:08' => array(
            'bookname'=> 'Math',
            'return'=> 'false'
        ),
        '12:09' => array(
            'bookname'=> 'Math',
            'return'=> 'false'
        ),
        '12:10' => array(
            'bookname'=> 'Math',
            'return'=> 'false'
        ),
        '12:11' => array(
            'bookname'=> 'Math',
            'return'=> 'false'
        ),
        '12:12' => array(
            'bookname'=> 'Math',
            'return'=> 'false'
        ),
    ),
   )
 )

Answer 1

试试这个：

检查数组是否为空，然后按如下所述添加数组：

$val = '';
foreach($data['deptIDid']['userid'] as $key=>$d) {
 if(trim($data['deptIDid']['userid'][$key]['bookname']) != '') {
    $val= $data['deptIDid']['userid'][$key]['bookname'];
 }
 if(empty($d) || $data['deptIDid']['userid'][$key]['bookname'] == '') {
    $data['deptIDid']['userid'][$key] = array('bookname'=> $val,'return'=> 'false');
 }
}
print '<pre>';print_r($data);
exit;

输出：

Answer 2

调整了Dhara的代码：

$prevData = [];
foreach($data['deptIDid']['userid'] as $key => $d) {
    if(empty($d)) {
        $data['deptIDid']['userid'][$key] = $prevData;
    } else {
        $prevData = $d;
    }
}

Answer 3

foreach($data['deptIDid']['userid'] as $key=>$val)
{   
    if(count($val)>0)
    {
        if($val['bookname']=="")
        {
            $val['bookname']=$tamp['bookname']; 
        }
        else if($val['return'] == "")
        {
                $val['return']=$tamp['return'];
        }
        $tamp = $val;   
        $tarray[$key] = $val;

    }
    else
    {
        $tarray[$key]=$tamp;
    }
}
