我想从深度嵌套的数组中提取数据。我正在寻找一个函数，该函数将产生符合某些条件的数组的某些部分。我正在寻找 'i' => 'p' 子数组下找到的数据 给出下面的嵌套数组：
[
'a' => [
'i' => [
'p' => [
'v' => [
'age' => 10,
'name' => 'John',
'city' => 'Seattle'
],
'l' => [
'referee' => 'Jane Smith'
],
'm' => [
'referee' => 'Jane Smith'
],
]
]
],
'b' => [
'i' => [
'p' => [
'sibling' => 'Peter'
]
],
],
'c' => [
'i' => [
'p' => [
'material' => [
'i' => [
'p' => [
'marketId' => [
'title' => 'marketplaceId'
],
'color' => [
'i' => [
'p' => [
'value' => [
'title' => 'Mr',
"type" => "string"
],
'language' => 'C++'
]
]
],
],
]
]
]
],
],
'd' => [
'i' => [
'p' => [
'schedule' => [
'i' => [
'p' => [
'value' => [
'title' => 'your value',
'description' => 'your description'
]
]
]
]
]
]
],
'e' => [
'i' => [
'p' => [
'value' => [
'title' => 'your value',
'description' => 'your description'
],
'language' => [],
'marketplace' => []
]
],
]
]
我正在寻找类似的东西：
[
'a' => [
'v' => [
'age' => 10,
'name' => 'John',
'city' => 'Seattle'
],
'l' => [
'referee' => 'Jane Smith'
],
'm' => [
'referee' => 'Jane Smith'
],
],
'b' => [
'sibling' => 'Peter'
],
'c' => [
'material' => [
'marketId' => [
'title' => 'marketplaceId'
],
'color' => [
'value' => [
'title' => 'Mr',
"type" => "string"
],
'language' => 'C++'
],
]
],
'd' => [
'schedule' => [
[
'value' => [
'title' => 'your value',
'description' => 'your description'
]
]
]
],
'e' => [
[
'value' => [
'title' => 'your value',
'description' => 'your description'
],
'language' => [],
'marketplace' => []
]
]
]
我尝试过这个功能：
function getIPData($array, $prefix = '') {
$return = [];
foreach ($array as $key => $value) {
if (!empty($value['i']['p'])) {
$return = array_merge($return, getIPData($value['i']['p'], $prefix . $key . '_'));
} else {
echo "Prefix: $prefix Key: $key \n";
$return[$prefix . $key] = $value;
}
}
return $return;
}
但它产生以下数组：
Array
(
[a_v] => Array
(
[age] => 10
[name] => John
[city] => Seattle
)
[a_l] => Array
(
[referee] => Jane Smith
)
[a_m] => Array
(
[referee] => Jane Smith
)
[b_sibling] => Peter
[c_material_marketId] => Array
(
[title] => marketplaceId
)
[c_material_color_value] => Array
(
[title] => Mr
[type] => string
)
[c_material_color_language] => C++
[d_schedule_value] => Array
(
[title] => your value
[description] => your description
)
[e_value] => Array
(
[title] => your value
[description] => your description
)
[e_language] => Array
(
)
[e_marketplace] => Array
(
)
)
您的代码非常接近实现目标。这是我的方法。
此外，如果您需要深度控制，您可以添加深度和 maxDepth 来控制嵌套递归行为。
功能：
function getIPData($array) {
$return = [];
foreach ($array as $key => $value) {
if (!empty($value['i']['p'])) {
$value = $value['i']['p'];
}
if (is_array($value)) {
$value = getIPData($value);
}
$return[$key] = $value;
}
return $return;
}
输出：
Array
(
[a] => Array
(
[v] => Array
(
[age] => 10
[name] => John
[city] => Seattle
)
[l] => Array
(
[referee] => Jane Smith
)
[m] => Array
(
[referee] => Jane Smith
)
)
[b] => Array
(
[sibling] => Peter
)
[c] => Array
(
[material] => Array
(
[marketId] => Array
(
[title] => marketplaceId
)
[color] => Array
(
[value] => Array
(
[title] => Mr
[type] => string
)
[language] => C++
)
)
)
[d] => Array
(
[schedule] => Array
(
[value] => Array
(
[title] => your value
[description] => your description
)
)
)
[e] => Array
(
[value] => Array
(
[title] => your value
[description] => your description
)
[language] => Array
(
)
[marketplace] => Array
(
)
)
)
