Medoo MySQL没有读取变量

Question

我使用的是Medoo MySQL框架，但在WHERE语句中使用IN时遇到了这个问题：

$test = '1,2,3,4';

$count = $database->count("products", [
    "AND" => [
        "category_id" => $category['id'],
        "id" => [$test]
    ]
]);

计数结果应为4，但我得到1.但是：

$count = $database->count("products", [
    "AND" => [
        "category_id" => $category['id'],
        "id" => [1,2,3,4]
    ]
]);

给我4个正确的结果。任何想法？提前谢谢！

Answer 1

试试这个......

$test = array(1,2,3,4);

$count = $database->count("products", [
    "AND" => [
        "category_id" => $category['id'],
        "id" => $test // variable without []
    ]
]);

Answer 2

$test = '1,2,3,4';是一个字符串。要将其转换为数组，您需要使用：

$test = explode(',', '1,2,3,4');

$count = $database->count("products", [
    "AND" => [
        "category_id" => $category['id'],
        "id" => $test
    ]
]);

Answer 3

此处发布了以下解决方案： https://github.com/catfan/Medoo/issues/637

$values = '2,123,234,54';

$database->select("account", "user_name", [
    "OR" => [
        "user_id" => explode(',',$values)
    ]
]);
