我在PHP中合并了几个像这样的数组
//all the other stuff
$array1 = (array) $new;
$array2 = (array) $info;
$ab = array('a' => $array1, 'b' => $array2);
print_r($ab);
print_r($ab)给我这样的话：
Array
(
[a] => Array
(
[entries] => Array
(
[0] => stdClass Object
(
[title] => Serial - This American Life
[id] => Serial is a podcast from the creators of This American Life, hosted by Sarah Koenig.
)
[1] => stdClass Object
(
[title] => This American Life - This American Life
[id] => This American Life is a weekly public radio show, heard by 2.2 million people on more than 500 stations.
)
[2] => stdClass Object
(
[title] => Real Crime Profile - Real Crime Profile
[id] => Podcast talking about criminal cases and personality profiling.
)
)
)
[b] => Array
(
[entries] => Array
(
[0] => stdClass Object
(
[artistName] => This American Life

这与我正在寻找的内容很接近，但理想情况下，我想更加简化这一点，因此我没有a和b ＆＃34;树＆＃34;在这个数组中。
这就是我想要的结果：
Array
(
[a] => Array
(
[entries] => Array
(
[0] => stdClass Object
(
[title] => Serial - This American Life
[id] => Serial is a podcast from the creators of This American Life, hosted by Sarah Koenig.
[artistName] => This American Life

)
[1] => stdClass Object
(
[title] => This American Life - This American Life

[2] => stdClass Object

)
)
)
)
我也试过了array_merge_recursive($array1['entries'],$array2['entries']，但这给了我这样的东西（6个对象[2个来自一个数组，4个来自另一个]而不是3个）：
Array
(
[0] => stdClass Object
(
[title] => Serial - This American Life

关于如何将这些合并为3个对象的想法？
答案 0 :(得分：1)
这只是一个示例，用于解释如何将my answer中的函数multiArrayCombine用于另一个问题：
foreach( $array['a']['entries'] as &$val ) $val = (array) $val;
foreach( $array['b']['entries'] as &$val ) $val = (array) $val;
$result = multiArrayCombine( $array['a']['entries'], $array['b']['entries'], T_OBJECT_CAST );
$array['a']['entries'] = $result;
unset( $array['b'] );
print_r( $array );
正如我所说，这只是一个例子：该函数可以选择返回对象但不分析它。您可以修改它以处理对象并直接使用它，而不需要前两行。
答案 1 :(得分：0)
尝试
for($i=0;$i<count($array1['entries']); $i++){
$array3['entries'][$i] =(object) ((array) $array1['entries'][$i] + (array) $array2['entries'][$i]);
}
答案 2 :(得分：0)
函数array_replace_recursive将执行您描述的操作。 array_merge_recursive的问题在于，当遇到顺序数组时，它会连接合并数组的值，而不是用相同的索引覆盖这些条目。 array_replace_recursive本质上是相同的，但始终将数组视为关联数，并且永远不会将它们连接起来。
http://php.net/manual/en/function.array-replace-recursive.php
由于您的叶子节点都是stdObject并且array_merge_recursive不能合并对象，因此您需要先将它们转换为数组。
示例：
<?php
$a = [
'entries' => [
(object) [
'title' => 'Alpha',
'id' => 'Alpha ...'
],
(object) [
'title' => 'Beta',
'id' => 'Beta ...'
]
]
];
$b = [
'entries' => [
(object) [
'artistName' => 'Alpha artist',
'feedUrl' => 'fdsfsdf'
],
(object) [
'artistName' => 'Beta artist',
'feedUrl' => 'gfdsgfds'
]
]
];
function convert_objects($array) {
array_walk_recursive($array, function(&$value) {
$value = (array) $value;
});
return $array;
}
var_export(array_replace_recursive(convert_objects($a), convert_objects($b)));
打印哪些：
array (
'entries' =>
array (
0 =>
array (
'title' => 'Alpha',
'id' => 'Alpha ...',
'artistName' => 'Alpha artist',
'feedUrl' => 'fdsfsdf',
),
1 =>
array (
'title' => 'Beta',
'id' => 'Beta ...',
'artistName' => 'Beta artist',
'feedUrl' => 'gfdsgfds',
),
),
)
