PHP Array_Push无效

我正在尝试组织一组通过数据库查询获得的结果。以下是我用来执行此操作的代码：

$time_slots = $wpdb->get_results($query);
print_r($time_slots); 
echo ("<br/><br/><br/><br/>");
/*organize slots into array*/


$openings = array(); 
foreach($time_slots as $ts)
{
    if(empty($openings))
    {
        echo("Empty Array: ");
        echo ("<br/>");
        echo ("<br/>");
        echo("Inserting: ");
        print_r($ts); 
        echo ("<br/>");
        echo ("<br/>");
        $openings[$ts->route_date] = $ts; 
        echo("contents of Opening: ");
        echo ("<br/>");
        echo ("<br/>");
        print_r($openings); 
        echo ("<br/><br/><br/><br/>");

    }
    elseif (array_key_exists($ts->route_date, $openings)) 
    {
        echo("Same Day");
        echo ("<br/>");
        echo ("<br/>");
        echo("Inserting: ");
        print_r($ts); 
        echo ("<br/>");
        echo ("<br/>");
        array_push($openings[$ts->route_date][$ts->name], $ts); 
        echo("contents of Opening: ");
        echo ("<br/>");
        echo ("<br/>");
        print_r($openings); 
        echo ("<br/><br/><br/><br/>");
    }
    else
    {
        echo("New Day : ");
        echo ("<br/>");
        echo ("<br/>");
        echo("Inserting: ");
        print_r($ts); 
        echo ("<br/>");
        echo ("<br/>");
        $openings[$ts->route_date] = $ts; 
        echo("contents of Opening: ");
        echo ("<br/>");
        echo ("<br/>");
        print_r($openings); 
        echo ("<br/><br/><br/><br/>"); 
    }
}

/*return results*/
$result['openings'] = $openings; 
$result['time'] = $time_slots;  
$result['begin'] = $begin; 
$result['end'] = $end; 
$result['query'] = $query; 
$result['type'] = "success"; 
$result = json_encode($result);
print_r($openings);

以下是print_r $ts：

时的单个结果 
 stdClass Object ( [route_date] => 2014-01-10 [name] => 2 [openings] => 1 [appointments] => 0 )

这是一个循环的样子。你会注意到逻辑是有效的，并且一切都在应该去的地方，但是添加t：

> Empty Array: 

Inserting: stdClass Object ( [route_date] => 2014-01-10 [name] => 0 [openings] => 1 [appointments] => 0 ) 

contents of Opening:

Inserting: stdClass Object ( [route_date] => 2014-01-11 [name] => 1 [openings] => 1 [appointments] => 0 ) 

contents of Opening:

如果说完了，我得到了这个结果：

您会注意到只有第一个对象的第一个实例被添加到新数组$openings。

更新：

我刚刚意识到我需要一个多维数组，但是当我尝试添加第二个维度时，我收到以下错误：

 Cannot use object of type stdClass as array

我在这里做错了什么？我想要一个数组$openings[route_date][number]，但我无法让它工作。任何帮助都会很棒。

答案 0 :(得分：2)

这是因为array_push()适用于数组，而不是对象。您应该将stdClass转换为数组。尝试使用：

$ts = (array) $ts;

答案 1 :(得分：0)

在array_push($openings[$ts->route_date][$ts->name], $ts);中，第一个参数似乎不是数组。如果第一个参数不是数组，array_push（）将发出警告。

This should be array_push($openings, $ts);

我做了一个很好的例子。

//I'm using mysql and I will switch to  MySQLi or PDO_MySQL later) 

$query = "SELECT * FROM events";
$result = mysql_query($query);
$openings = array();
while ($row = mysql_fetch_object($result)) {
    array_push($openings, $row); 
}
print_r($openings);

//output

Array
(
    [0] => stdClass Object
        (
            [idevent] => 1
            [event] => Event1
            [event_date] => 2014-01-06
        )

    [1] => stdClass Object
        (
            [idevent] => 2
            [event] => Event2
            [event_date] => 2014-01-07
        )

)

答案 2 :(得分：0)

事实证明我需要做一些事情。这是我需要的代码：

    $time_slots = $wpdb->get_results($query);
echo("<pre>"); 
//print_r($time_slots); 

echo ("<br/><br/><br/><br/>");
/*organize slots into array*/


$openings = array(); 
foreach($time_slots as $ts)
{
    if(empty($openings))
    {
        echo("Empty Array: ");
        echo ("<br/>");

        echo("Inserting: ");
        echo ("<pre>");
        print_r($ts); 
        echo("</pre>");
        echo ("<pre>");
        $openings[$ts->route_date][$ts->name] = $ts; <--- Needed to add the [$ts->name]
        echo("</pre>");
        echo("contents of Opening: ");
        echo ("<pre>");
        print_r($openings); 
        echo ("</pre>");

    }
    elseif (array_key_exists($ts->route_date, $openings)) 
    {
        echo("Same Day");
        echo("Inserting: ");
        echo ("<pre>");
        print_r($ts); 
        echo("</pre>");
        $openings[$ts->route_date][$ts->name]=$ts; 
        echo("contents of Opening: ");
        echo ("<br/>");
        echo ("<br/>");
        print_r($openings); 
        echo ("<br/><br/><br/><br/>");
    }
    else
    {
        echo("New Day : ");
        echo("Inserting: ");
        echo ("<pre>");
        print_r($ts); 
        echo("</pre>");
        echo ("<pre>");
        $openings[$ts->route_date][$ts->name] = $ts; 
        echo("</pre>");
        echo("contents of Opening: ");
        echo ("<pre>");
        print_r($openings); 
        echo ("</pre>");
    }
