返回带有数字键的数组PHP？
为此，将foreach循环与[]一起使用并实现arary_values()方法。
示例
<!DOCTYPE html>
<html>
<body>
<?php
$details = [
[
"id" => "10001",
"firstName" => "John",
"lastName" => "Doe"
],
[
"id" => "10002",
"firstName" => "David",
"lastName" => "Miller"
]
];
foreach ($details as $k=> $v) {
$someDetails[$v['id']][] = ['LASTNAME' => $v['lastName'], 'FIRSTNAME'=> $v['firstName']];
}
print_r(array_values($someDetails));
?>
</body>
</html>输出结果
Array ( [0] => Array ( [0] => Array ( [LASTNAME] => Doe [FIRSTNAME] => John ) ) [1] => Array ( [0] => Array ( [LASTNAME] => Miller [FIRSTNAME] => David ) ) )
