我需要合并一个PHP数组,这个数组有2个数组,名为“targetXX”,我可以有2个或更多。每个目标都有相同的键,对于每个键,我有一个带有2个值a和b的数组,两个目标中的a总是相同的,但是我需要像这样合并两个B值:
Array
(
[0] => Array
(
[target] => hitcount(stats.asdf1.requests, "1min")
[datapoints] => Array
(
[0] => Array
(
[0] => 1200
[1] => 1392282200
)
[1] => Array
(
[0] => 1400
[1] => 1392282260
)
[2] => Array
(
[0] => 600
[1] => 1392282320
)
[3] => Array
(
[0] => 200
[1] => 1392282380
)
[4] => Array
(
[0] => 400
[1] => 1392282440
)
[5] => Array
(
[0] => 600
[1] => 1392282500
)
)
)
[1] => Array
(
[target] => hitcount(stats.asdf.requests, "1min")
[datapoints] => Array
(
[0] => Array
(
[0] => 4321
[1] => 1392282200
)
[1] => Array
(
[0] => 76567
[1] => 1392282260
)
[2] => Array
(
[0] => 5556
[1] => 1392282320
)
[3] => Array
(
[0] => 7675
[1] => 1392282380
)
[4] => Array
(
[0] => 2344
[1] => 1392282440
)
[5] => Array
(
[0] => 0999
[1] => 1392282500
)
)
)
结果:
Array
(
[0] => Array
(
[target] => hitcount(stats.asdf1.requests, "1min")
[datapoints] => Array
(
[0] => Array
(
[0] => 1200
[1] => 1392282200
[2] => 4321
)
[1] => Array
(
[0] => 1400
[1] => 1392282260
[2] => 76567
)
[2] => Array
(
[0] => 600
[1] => 1392282320
[2] => 5556
)
[3] => Array
(
[0] => 200
[1] => 1392282380
[2] => 7675
)
[4] => Array
(
[0] => 400
[1] => 1392282440
[2] => 2344
)
[5] => Array
(
[0] => 600
[1] => 1392282500
[2] => 0999
)
)
)

内置function array_merge
可能会为您完成工作。实际上,您需要合并每个子数组,因为array_merge_recursive
函数不处理索引。
$newArray = array();
foreach ($myArray['target2'] as $key => $arr) {
$newArray['target'][$key] = array_merge($myArray['target1'][$key], $arr[1]);
}
将一个或多个数组的元素合并在一起,以便将一个值的值附加到前一个数组的末尾。它返回结果数组。
如果输入数组具有相同的字符串键,则该键的后一个值将覆盖前一个键。但是,如果数组包含数字键,则后面的值不会覆盖原始值,但会附加。
如果要合并的密钥超过2个,则可以多次循环算法。

使用array_merge()
来实现这一目标:
$newArray = array();
foreach ($myArray['target2'] as $key => $innerArr1) {
$newArray['target'][$key] = array_merge(
$myArray['target1'][$key], /* 0th and 1st index */
array($innerArr1[1]) /* 2nd index */
);
}
print_r($newArray);
输出:
Array
(
[target] => Array
(
[0] => Array
(
[0] => 333333
[1] => 13
[2] => 99
)
[1] => Array
(
[0] => 444444
[1] => 15
[2] => 98
)
[2] => Array
(
[0] => 555555
[1] => 17
[2] => 97
)
)
)
