我目前正在從一個(gè)數(shù)組中的 sql 語(yǔ)句返回結(jié)果，如下所示：$results = []; foreach($promotionTool as $p){ $results[] = $p; } return $results;我的控制臺(tái)在具有以下結(jié)構(gòu)的對(duì)象中顯示：(2) [{…}, {…}] 0: codeID: "41" code: "123ABC" rule_type: "Category" attribute_type: "identifier" attribute_title: "category number" attribute_value: "234" 1: codeID: "41" code: "123ABC" rule_type: "Category" attribute_type: "amount" attribute_title: "percent" attribute_value: "25" 這顯示了我期望的數(shù)據(jù)，但我對(duì)如何重組它有點(diǎn)迷茫，以便我可以在某些級(jí)別上進(jìn)行分組，最后只返回一個(gè)屬性數(shù)組，如下所示： codeID code rule_type array( 0: attribute_type: "identifier" attribute_title: "category number" attribute_value: "234" 1: attribute_type: "amount" attribute_title: "percent" attribute_value: "25" )我將如何重構(gòu)我的 foreach 以這種方式在多個(gè)級(jí)別進(jìn)行分組？

我想這就是你要找的：
<?php
$input = [
[
'codeID' => "41",
'code' => "123ABC",
'rule_type' => "Category",
'attribute_type' => "identifier",
'attribute_title' => "category number",
'attribute_value' => "234"
],
[
'codeID' => "41",
'code' => "123ABC",
'rule_type' => "Category",
'attribute_type' => "amount",
'attribute_title' => "percent",
'attribute_value' => "25"
]
];
$output = [];
array_walk($input, function ($e) use (&$output) {
$output[$e['codeID']][$e['code']][$e['rule_type']][] = [
'attribute_type' => $e['attribute_type'],
'attribute_title' => $e['attribute_title'],
'attribute_value' => $e['attribute_value']
];
});
print_r($output);
這可能是一個(gè)更容易閱讀的變體：
array_walk($input, function ($e) use (&$output) {
$codeID = &$e['codeID'];
$code = &$e['code'];
$rule_type = &$e['rule_type'];
$output[$codeID][$code][$rule_type][] = [
'attribute_type' => $e['attribute_type'],
'attribute_title' => $e['attribute_title'],
'attribute_value' => $e['attribute_value']
];
});
輸出顯然是：
Array
(
[41] => Array
(
[123ABC] => Array
(
[Category] => Array
(
[0] => Array
(
[attribute_type] => identifier
[attribute_title] => category number
[attribute_value] => 234
)
[1] => Array
(
[attribute_type] => amount
[attribute_title] => percent
[attribute_value] => 25
)
)
)
)
)
