在多维数组中插入数组

Question

即时尝试插入一个数组到我的多维数组中，在代码的第一个sql部分它工作正常，但是当我使用array_splice它似乎并不明白，即时通讯尝试插入整个阵列，只是提出了其他的东西。 任何人都可以帮助我得到正确的答案？

这是结果我尝试获得：

Array 
(
[0] => Array 
    (
     [0] => 1 
     [1] => företag1 
    ) 
[1] => Array 
    (
     [0] => 3 
     [1] => subföretag1 
    ) 

[2] => Array 
    (
     [0] => 5 
     [1] => subföretag2 
    ) 

[3] => Array 
    (
     [0] => 6 
     [1] => subföretag3 
    ) 

[4] => Array 
    (
     [0] => 2 
     [1] => företag2 
    ) 

[5] => Array 
    (
     [0] => 4 
     [1] => företag3 
    ) 
) 

，这就是我得到：

Array 
(
[0] => Array 
    (
     [0] => 1 
     [1] => företag1 
    ) 

[1] => 3 
[2] => 6 
[3] => subföretag3 
[4] => 5 
[5] => subföretag2 
[6] => subföretag1 
[7] => Array 
    (
     [0] => 2 
     [1] => företag2 
    ) 

[8] => Array 
    (
     [0] => 4 
     [1] => företag3 
    ) 

) 

这是数组即时通讯使用：

$partarray=array($row['id'],$row['name']); 
in the first part: $partarray=array(random number from db,random name); 
in the second part: $partarray=array(random number from db,random name); 

这是当前使用的代码：

$departments = array(); 
$sth = $pdo->prepare('SELECT id, name FROM departments WHERE companyid = 1 AND subgroupof = 0'); 
$sth->execute(); //executes the array 
while($row = $sth->fetch()){ 
    $partarray=array($row['id'],$row['name']); 
    array_push($departments, $partarray); 
} 
$sth = $pdo->prepare('SELECT * FROM departments WHERE companyid = 1 AND subgroupof != 0'); 
$sth->execute(); //executes the array 
while($row = $sth->fetch()){ 
     $partarray=array($row['id'],$row['name']); 
     array_splice($departments, $row['subgroupof'], 0, $partarray); 
} 
print("<pre>".print_r($departments,true)."</pre>"); 

Answer 1

试试这个。

$departments = array(); 
$sth = $pdo->prepare('SELECT id, name FROM departments WHERE companyid = 1 AND subgroupof = 0'); 
$sth->execute(); //executes the array 

while($row = $sth->fetch()){ 
    $departments[] = array($row['id'], $row['name']); 

    $sub_sth = $pdo->prepare(
     "SELECT id, name FROM departments WHERE companyid = 1 AND subgroupof = {$row['id']}" 
    ); 

    $sub_sth->execute(); //executes the array 
    while($sub_row = $sub_sth->fetch()) { 
      $departments[] = array($sub_row['id'], $sub_row['name']); 
    } 
} 

print("<pre>".print_r($departments,true)."</pre>");
