PHP Array_Push ไม่ทำงาน

ฉันกำลังพยายามจัดระเบียบชุดผลลัพธ์ที่ได้รับผ่านการสืบค้นฐานข้อมูล นี่คือรหัสที่ฉันใช้เพื่อทำสิ่งนี้:

$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);

นี่คือลักษณะของผลลัพธ์เดียวเมื่อฉัน print_r the $ts:

 stdClass Object ( [route_date] => 2014-01-10 [name] => 2 [openings] => 1 [appointments] => 0 )

นี่คือลักษณะของหนึ่งวง คุณจะสังเกตเห็นว่าตรรกะใช้งานได้ และทุกอย่างดำเนินไปในที่ที่ควรไป แต่การเพิ่ม t:

> Empty Array: 

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

contents of Opening: 

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



Same Day

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

contents of Opening: 

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



Same Day

Inserting: stdClass Object ( [route_date] => 2014-01-10 [name] => 2 [openings] => 1 [appointments] => 0 ) 

contents of Opening: 

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



Same Day

Inserting: stdClass Object ( [route_date] => 2014-01-10 [name] => 3 [openings] => 1 [appointments] => 0 ) 

contents of Opening: 

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



Same Day

Inserting: stdClass Object ( [route_date] => 2014-01-10 [name] => 4 [openings] => 1 [appointments] => 0 ) 

contents of Opening: 

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



New Day : 

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

contents of Opening: 

Array ( [2014-01-10] => stdClass Object ( [route_date] => 2014-01-10 [name] => 0 [openings] => 1 [appointments] => 0 ) [2014-01-11] => stdClass Object ( [route_date] => 2014-01-11 [name] => 0 [openings] => 1 [appointments] => 0 ) ) 



Same Day

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

contents of Opening: 

Array ( [2014-01-10] => stdClass Object ( [route_date] => 2014-01-10 [name] => 0 [openings] => 1 [appointments] => 0 ) [2014-01-11] => stdClass Object ( [route_date] => 2014-01-11 [name] => 0 [openings] => 1 [appointments] => 0 ) )

เมื่อพูดและทำเสร็จแล้ว ฉันจะได้ผลลัพธ์ดังนี้:

คุณจะสังเกตเห็นว่ามีการเพิ่มเฉพาะอินสแตนซ์แรกของออบเจ็กต์แรกในอาร์เรย์ใหม่ $openings

อัปเดต:

ฉันเพิ่งรู้ว่าฉันต้องการอาร์เรย์หลายมิติสำหรับสิ่งนี้ แต่เมื่อฉันพยายามเพิ่มมิติที่สอง ฉันได้รับข้อผิดพลาดต่อไปนี้:

ฉันทำอะไรผิดที่นี่? ฉันต้องการอาร์เรย์เดียว $openings[route_date][number] แต่ใช้งานไม่ได้ ความช่วยเหลือใด ๆ จะดีมาก

 Cannot use object of type stdClass as array

เป็นเพราะ 

$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);
ใช้งานได้กับอาร์เรย์ ไม่ใช่วัตถุ คุณควรแปลง print_r ของคุณเป็นอาร์เรย์ ลองใช้:

ใน array_push() อาร์กิวเมนต์แรกของคุณดูเหมือนจะไม่ใช่อาร์เรย์ array_push() จะส่งคำเตือนหากอาร์กิวเมนต์แรกไม่ใช่อาร์เรย์

$ts = (array) $ts;

ฉันได้ทำตัวอย่างที่ใช้งานได้ดี

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

ปรากฎว่าฉันต้องทำสองสิ่ง นี่คือรหัสที่ฉันต้องการ:

//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
        )

อย่างไรก็ตาม โปรดพิมพ์อาร์เรย์ดังกล่าวโดยเพิ่ม 

    $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("Inserting: ");
        echo ("<pre>");
        print_r($ts);

        echo ("<pre>");
