目前，我已经能够找到正确的表格并print_r数组的内容。现在，我试图遍历该数组，并根据id显示该数组中的用户名和点。这就是数组的样子
Array
(
[0] => stdClass Object
(
[id] => 5a61d2f40394d
[first] => Test
[last] => Guy3
[company] => 123 Company
[points] => 50
[url] => https://example.com/points/?user=5a61d2f40394d
[created] => 0000-00-00 00:00:00
[updated] => 2018-01-19 06:22:42
)
[1] => stdClass Object
(
[id] => 5a61cdddc359d
[first] => Test
[last] => Guy1
[company] => 123 Company
[points] => 0
[url] => https://example.com/points/?user=5a61cdddc359d
[created] => 0000-00-00 00:00:00
[updated] => 2018-01-19 05:52:13
)
[2] => stdClass Object
(
[id] => 5a61d054a0915
[first] => Test
[last] => Guy2
[company] => 123 Company
[points] => 0
[url] => https://example.com/points/?user=5a61d054a0915
[created] => 0000-00-00 00:00:00
[updated] => 2018-01-19 06:02:44
)
)
这是我到目前为止所写的内容，而且我已经能够找到该ID，但现在我想访问这些点并在之后更新它们。
global $wpdb; //this is wordpress so I'm accessing the database
//here I'm reading the variable ?user= in the url
$queryURL = parse_url( html_entity_decode( esc_url( add_query_arg( $arr_params ) ) ) );
parse_str( $queryURL['query'], $getVar );
$user = $getVar['user'];
$customers = $wpdb->get_results("SELECT * FROM `wpjw_skmember`;");
//I've found the users id but now I need to update their points but I don't know how.
$first = array_column($customers, 'id');
foreach($first as $value) {
if ($value == $user) {
echo 'user found'
}
}
答案 0 :(得分：1)
如果您的$ customers数组具有上面发布的格式，那么访问其中的值将如下所示：

因此，您可以遍历$ customers并测试该数组中的每个客户，以查看ID值是否匹配，然后访问其他值：
echo $customers[0]->last; // returns "Guy3"
在识别匹配用户后使用break将退出foreach循环，防止其他不必要的迭代。
