如何将这两个数组合并在一起?
Array
(
[0] => Array
(
[id] => 5
[cnt] => 14
)
[1] => Array
(
[id] => 8
[cnt] => 2
)
)
Array
(
[0] => Array
(
[id] => 8
[binding] => hardcover
)
[1] => Array
(
[id] => 5
[binding] => softcover
)
)
预期结果是:
Array
(
[0] => Array
(
[id] => 5
[binding] => softcover
[cnt] => 14
)
[1] => Array
(
[id] => 8
[binding] => hardcover
[cnt] => 2
)
)
这两个数组的合并应该在[id]值上进行,而不是在任何类型的数组上进行。我怎么能用PHP快速完成这个呢?

$output = array();
$arrayAB = array_merge($arrayA, $arrayB);
foreach ( $arrayAB as $value ) {
$id = $value['id'];
if ( !isset($output[$id]) ) {
$output[$id] = array();
}
$output[$id] = array_merge($output[$id], $value);
}
var_dump($output);
如果您想重置输出键,可以选择:
$output = array_values($output);
