[英]How to call function from object stored in array in PHP?
I can't call / access the Id function from Product class which is stored in $products
array in the foreach
loop.我无法从产品 class 调用/访问 ID function,它存储在
foreach
循环的$products
数组中。 ( $product->Id()
) (
$product->Id()
)
I have tried我努力了
class Product
{
private $id;
public function __contruct($id)
{
$this->Id($id);
}
public function Id($value = '')
{
if (empty($value)) {
return $this->id;
} else {
$this->id = $value;
}
}
}
function testArray()
{
global $conn;
$searchQuery = "SELECT * FROM products";
$stmt = $conn->prepare($searchQuery);
$stmt->execute();
$result = $stmt->get_result();
$products = array();
while ($row = $result->fetch_assoc()) {
$products[] = new Product(
$row["id"]
);
}
foreach ($products as $product) {
print_r($product->Id());
}
$stmt->close();
}
You misspelled你拼错了
public function __contruct($id)
Change it to:将其更改为:
public function __construct($id)
