Question

我想在单列中以逗号分隔存储多个数据，并在不同行的php的帮助下获取数据就像在列视图中一样，它看起来像这样 - 牙刷-1234，玻璃-1234，在那里1234是产品ID 我希望在php中获取这些数据，每行包含所有细节的分隔值。喜欢

   <?php $sql="select product_name form products where product_id=1234" ?>

因此可以通过 - 和单列来获取数据并将其分开。

您希望将逗号分隔的数据显示为单独的行。你可以试试这个。

<?
//Here is the complete example of your code by using MYSQLi Object Oriented:
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

$sql = "select product_id,product_name form products where product_id=1234";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // output data of each row
    $yourData = array();
    while($row = $result->fetch_assoc()) {
        $yourData[$row['product_id']] = explode(",",$row['product_name']);
    }

    if(count($yourData) > 0){
        foreach ($yourData as $key => $value) {
            foreach ($value as $productname) {
                echo "Product ID >> ".$key. " -- Product Name >> ".$productname;
            }
        }
    }
} 
else 
{
    echo "0 results";
}
$conn->close();

?>

旁注：如果您在应用中使用mysql_*，建议您使用mysqli_*或PDO因为mysql_*已被弃用并且在PHP 7中不可用。
