合并两个数组合并为一个数组（同文键） [英] Merge two arrays into one array (identic keys)
问题描述
我觉得这是一个很简单的问题，但无法弄清楚如何这一点。我有这两个数组：
I think this is a very simple question, but can't figure out how to this. I've these two arrays:
(
[0] => Array
(
[accordion_title] => [accordion-title]Title 1[/accordion-title]
)
[1] => Array
(
[accordion_title] => [accordion-title]Title 2[/accordion-title]
)
)
(
[0] => Array
(
[accordion_content] => [accordion-content]Content 1[/accordion-content]
)
[1] => Array
(
[accordion_content] => [accordion-content]Content 2[/accordion-content]
)
)
我怎么能合并/合并他们，他们是这样的？
How can I combine/merge them that they look like this?
(
[0] => Array
(
[accordion_title] => [accordion-title]Title 1[/accordion-title]
[accordion_content] => [accordion-content]Content 1[/accordion-content]
)
[1] => Array
(
[accordion_title] => [accordion-title]Title 2[/accordion-title]
[accordion_content] => [accordion-content]Content 2[/accordion-content]
)
)
感谢您的帮助。
推荐答案
您可以尝试用这种方式：
You can try in this way:
$array1 = array( array('accordion_title'=>'Title 1'),array('accordion_title'=>'Title 2') );
$array2 = array( array('accordion_content'=>'Content 1'),array('accordion_content'=>'Content 2') );
$array3 = array();
foreach( $array1 as $key => $array )
{
$array3[] = array( key($array) => current($array), key($array2[$key]) => current($array2[$key]) );
}
print_r( $array3 );
这是输出：
Array
(
[0] => Array
(
[accordion_title] => Title 1
[accordion_content] => Content 1
)
[1] => Array
(
[accordion_title] => Title 2
[accordion_content] => Content 2
)
)
更新：
通过这个功能您可以结合无限阵列（不仅二），即使它们有不同的大小：
Updated:
With this function you can combine infinite arrays (not only two), even if they have different sizes:
/* Groups passed arrays in an array of associative arrays with same keys and values
*
* @example $array1 = array( array('a'=>'val1'),array('a'=>'val2') );
* $array2 = array( array('b'=>'val3'),array('b'=>'val4') );
* $array3 = array( array('c'=>'val5'),array(),array('c'=>'val6') );
* multiArrayCombine( $array1, $array2, $array3 );
* return: array
* (
* 0 => array('a'=>'val1','b'=>'val3','c'=>'val5'),
* 1 => array('a'=>'val2','b'=>'val4'),
* 2 => array('c'=>'val6')
* )
*
* @param array $array1[, $array2[, $array3...]]
*
* @option const T_OBJECT_CAST cast returned assoc arrays as stdObject
*
* @return array
*/
function multiArrayCombine()
{
/* Get all passed parameters and T_OBJECT_CAST option: */
$args = func_get_args();
$asObject = ( T_OBJECT_CAST == end($args) );
if( $asObject ) array_pop( $args );
$retval = array(); # Init array to be returned
/* Retrieve highest passed arrays key: */
$max = 0;
foreach( $args as $array ) $max = max( $max, max( array_keys($array) ) );
/* Loop for each arrays key: */
for( $i=0; $i<=$max; $i++ )
{
/* Init associative array to add: */
$add = array();
/* Process actual key ($i) of each passed array: */
foreach( $args as $array )
{
/* If the key ($i) exists, add each passed array: */
if( isset($array[$i]) AND is_array($array[$i]) )
{
foreach( $array[$i] as $key => $val )
{ $add[$key] = $val; }
}
}
/* Add the obtained associative array to return array */
if( $asObject ) $retval[] = (object) $add;
else $retval[] = $add;
}
return $retval;
}
因此，用下面的code（三个数组）：
So, with the following code (three arrays):
$array1 = array( array('accordion_title'=>'Title 1'),array('accordion_title'=>'Title 2') );
$array2 = array( array('accordion_content'=>'Content 1'),array('accordion_content'=>'Content 2') );
$array3 = array( array('accordion_date'=>'Date 1'),array(),array('accordion_date'=>'Date 3') );
print_r( multiArrayCombine( $array1, $array2, $array3 ) );
的输出是：
Array
(
[0] => Array
(
[accordion_title] => Title 1
[accordion_content] => Content 1
[accordion_date] => Date 1
)
[1] => Array
(
[accordion_title] => Title 2
[accordion_content] => Content 2
)
[2] => Array
(
[accordion_date] => Date 3
)
)
<大骨节病> eval.in演示
- 现在，函数返回全部通过各行的值，不仅是第一个;
- 添加选项
T_OBJECT_CAST：传递常数<$ C $ C> T_OBJECT_CAST 数组列表之后，返回数组的行作为格式化为stdObjects而不是数组。
- Now the function return all passed values of each rows, not only the first;
- Added option
T_OBJECT_CAST: passing constantT_OBJECT_CASTafter the list of arrays, rows of returned array as formatted as stdObjects instead of arrays.
要允许未predetermined争论，我不格式化功能 multiArrayCombine（$ ARG1，ARG2 $ ......），我用的不是< A HREF =http://php.net/manual/en/function.func-get-args.php相对=nofollow> func_get_args（） 功能，即允许用户自定义函数接受可变长度参数列表。
Explanation:
To allow not predetermined arguments, I don't format function as multiArrayCombine( $arg1, $arg2, ... ), I use instead the func_get_args() function, that "allow user-defined functions to accept variable-length argument lists".
首先（在最新的更新），我检查，如果最后一个参数是predefined恒 T_OBJECT_CAST ：如果是这样，我设置 $ asObject 到真，然后我的弹出它关闭的参数数组的结束;目前在的$ args 变量我有每个传递数组的数组。
First of all (in the latest update), I check if the last argument is the predefined constant T_OBJECT_CAST: if it is, I set $asObject to True, then I pop-it off the end of arguments array; now in the $args variable I have an array with each passed arrays.
下一步：我检索所有通过阵列的最大键值;我选择这样的方式，而不是更舒服的foreach（$数组1为$行），以避免如果其他阵列中的一个具有多个第一行省略值。 最终没有数字键被省略了。
Next step: I retrieve the max key value of all passed arrays; i choose this way instead of more comfortable foreach( $array1 as $row ) to avoid to omit values if one of the other arrays have more rows than the first. Eventually not numeric keys are omitted.
然后，主回路：我处理原件阵列中的每一行，我添加其键和值排的意志加入到返回数组。 如果有重复键，只返回最后一个。
Then, the main loop: I process each row of originals arrays and I add their keys and values to row that will added to returned array. If there are duplicated keys, only the last is returned.
在处理每个数组后，我所获得的行（转换如果该选项被传递给对象）添加到阵列返回
After processing each array, i add the obtained row (converted to object if this option is passed) to returning array.
这就是全部！
