我有这些数组,但是我想让它只为“监视”类别回显一个数组,并想将选定的数组存储在PHP变量中,所以我必须尝试在网上搜索以找到解决方案,但没有成功。
$arr = [
'status' => 1,
'msg' => [
'total_records' => 5,
'total_pages' => 1,
'page_number' => 1,
'per_page' => 100,
'return_count' => 5,
'page_result' => [
0 => array
(
'items' => 200052001,
'code' => 501,
'category' => 'watch',
'price' => 50,
'stock' => 1,
),
1 => array
(
'items' => 200052001,
'code' => 401,
'category' => 'shirt',
'price' =>3,
'stock' => 1,
),
2 => array
(
'items' => 200052001,
'code' => 172758801,
'category' => 'watch',
'price' => 200,
'stock' => 1,
),
],
],
'errcode' => 0,
];

这应该可以解决问题。
$watch_array = array();
foreach($arr["msg"]["page_result"] AS $k => $item) {
if($item["category"] == "watch") {
$watch_array[] = $item;
}
}
您现在有了一个仅包含手表的数组。
要显示其内容,请使用:
print_r($watch_array);

根据您的要求检查此搜索功能。它完全动态,并具有递归性质。
function search($array, $key, $value)
{
$results = [];
if (is_array($array)) {
if (isset($array[$key]) && $array[$key] == $value) {
$results[] = $array;
}
foreach ($array as $subarray) {
$results = array_merge($results, search($subarray, $key, $value));
}
}
return $results;
}
$temp = search($arr, "category", "watch");
