之后 $single_array = array_reduce ($new_array, 'array_merge_recursive', array ());
我得到這個結果
array (size=9)
'key1' => string 'value1'
'key2' => string 'value2'
'key3' => string 'value3'
'key7' =>
array
0 => string 'value7'
1 => string 'value13'
'key8' =>
array
0 => string 'value8'
1 => string 'value14'
'key9' =>
array
0 => string 'value9'
1 => string 'value15'
'key19' => string 'value19'
'key20' => string 'value20'
'key21' => string 'value21'
但我想要那個
array
'key1' =>
array
0 => string 'value1'
'key2' =>
array
0 => string 'value2'
'key3' =>
array
0 => string 'value3'
'key7' =>
array
0 => string 'value7'
1 => string 'value13'
'key8' =>
array
0 => string 'value8'
1 => string 'value14'
'key9' =>
array
0 => string 'value9'
1 => string 'value15'
'key19' =>
array
0 => string 'value19'
'key20' =>
array
0 => string 'value20'
'key21' =>
array
0 => string 'value21'
這可能很簡單，但我已經阻塞了幾個小時。
簡而言之，我希望我的 array_merge_recursive 不是只向相同的值添加一個鍵，而是向那些不相同的值添加一個陣列 [0]。
編輯
一開始的代碼，目標是簡化它并知道生成的值以及結構的順序可以是隨機的。
<?php
$array = array(
'sensors' => array(
'0' => array(
'data' => array(
'0' => array(
'key1' => 'value1',
'key2' => 'value2',
'key3' => 'value3',
)
)
),
'1' => array(
'data' => array(
'0' => array(
'key7' => 'value7',
'key8' => 'value8',
'key9' => 'value9',
)
)
),
'2' => array(
'data' => array(
'0' => array(
'key7' => 'value13',
'key8' => 'value14',
'key9' => 'value15',
)
)
),
'3' => array(
'data' => array(
'0' => array(
'key19' => 'value19',
'key20' => 'value20',
'key21' => 'value21',
)
)
)
)
);
$new_array = array();
foreach ($array as $element1) {
foreach ($element1 as $j => $element2) {
foreach ($element2 as $element3) {
foreach ($element3 as $element4) {
$new_array[$j] = $element4;
$single_array = array_reduce($new_array, 'array_merge_recursive', array());
}
}
}
}
var_dump($single_array);

您可以array_walk_recursive在原始陣列上使用：
$result = [];
array_walk_recursive($array, function ($value, $key) use (&$result) {
$result[$key][] = $value;
});
在您提供的示例陣列上運行后，$result將是：
[
'key1' => ['value1'],
'key2' => ['value2'],
'key3' => ['value3'],
'key7' => ['value7', 'value13'],
'key8' => ['value8', 'value14'],
'key9' => ['value9', 'value15'],
'key19' => ['value19'],
'key20' => ['value20'],
'key21' => ['value21']
];

謝謝，我發現，我只是混淆了 in_array 和 is_array。我的錯
$array2 = array();
foreach ($single_array as $key1 => $value1) {
if (is_array($value1)) {
foreach($value1 as $key2 => $value2) {
$array2[$key1][$key2] = $value2;
}
}
else {
$array2[$key1][] = $value1;
}
}
var_dump($array2);
