如何将两个或多个mysql数组合并成一个

Question

我有两个有多行的表。我想这两个表的行组合成将被认定为一个阵列的一个多头排列 我写了这个代码

$posts_sql = $db->query("SELECT * FROM posts WHERE id < $lastpost AND position = submitter order by id DESC LIMIT 5"); 
$posts_all = $db->fetch_all($posts_sql); 
foreach($posts_all as $key => $posts_row){ 
$users_sql = $db->query("SELECT username,firstname,lastname,avatar FROM users WHERE username = '".$posts_row['submitter']."'"); 
$users_all = $db->fetch_assoc($users_sql); 
$data[] = $posts_row; 
$data[] = $users_all; 
} 

echo json_encode($data); 

它让重复阵列不正确的......

这是我的结果如何显示

[{ 
"id":"39", 
"hash":"070fcc8e73ba5f549f87", 
"post":"hello\n", 
"files":"", 
"location":", 
"GB","status":"1", 
"position":"dabblos", 
"submitter":"dabblos", 
"source":"text", 
"ip":"37.130.227.133", 
"stamp":"1390197699" 
}, 
{ 
"username":"dabblos", 
"firstname":"dabb", 
"lastname":"los", 
"avatar":"no_avatar.png" 
}] 

请帮我做它只是一个多头排列

我想看到的输出看起来像这样

{ 
"id":"39", 
"hash":"070fcc8e73ba5f549f87", 
"post":"hello\n", 
"files":"", 
"location":", 
"GB","status":"1", 
"position":"dabblos", 
"submitter":"dabblos", 
"source":"text", 
"ip":"37.130.227.133", 
"stamp":"1390197699" 
"username":"dabblos", 
"firstname":"dabb", 
"lastname":"los", 
"avatar":"no_avatar.png" 
}

未经测试：

$posts_sql = $db->query("SELECT * FROM posts WHERE id < $lastpost AND position = submitter order by id DESC LIMIT 5"); 
$posts_all = $db->fetch_all($posts_sql); 
foreach($posts_all as $key => $posts_row) { 
    $users_sql = $db->query("SELECT username,firstname,lastname,avatar FROM users WHERE username = '".$posts_row['submitter']."'"); 
    $users_all = $db->fetch_assoc($users_sql); 
    $data[] = $posts_row; 
    foreach($users_all as $user) 
    $data[] = $user; 
    } 
} 


echo json_encode($data); 

// when you use json_decode use the 'true' flag as in 
// $decodedJson = json_decode($json, true); 

Answer 2

合并他们，你json_encode他们面前：

$data[] = $posts_row; 
$data2[] = $users_all; 

$result = array_merge($data,$data2); 

echo json_encode($result); 

Answer 3

看看这个，我已经采取了示例值，它是作为你想

工作正常

$arr=array(array("abc"=>"1","def"=>"2"),array("abcc"=>"11","deff"=>"22")); 

echo json_encode($arr); 
$final = array(); 
foreach($arr as $item) { 
    $final = array_merge($final, $item); 
} 
print_r($final); 

输出

[{"abc":"1","def":"2"},{"abcc":"11","deff":"22"}]//json_array 

Array ([abc] => 1 [def] => 2 [abcc] => 11 [deff] => 22)//final array 

UPDATE

json_encode最终数组，你会得到期望的结果

echo json_encode($final); 

输出

{"abc":"1","def":"2","abcc":"11","deff":"22"}
