我想在单列中存储多个逗号分隔的数据，并在php的帮助下在不同的行中获取数据就像在柱视图中一样——牙刷-1234、玻璃-1234，上面1234是产品id我想在php中获得这些数据，每行都有单独的值及其所有细节。像
<?php $sql="select product_name form products where product_id=1234" ?>
因此，是否可以获取数据并通过和从单列中分离数据。
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();
?>
附带说明：如果您在应用程序中使用mysql_*，我建议您使用mysqli_*或PDO，因为mysql_*已弃用，在PHP7中不可用。
