PDO对象行打印两次

Question

so I'm designing a web interface for a database but when I try to print the values from a query they come in doubles since they are counting 2 indices for the same value. Anyone know why this is happening?

PHP Code:

function loadTable()
{
    $name  = $_GET["table"];
    $db    = new PDO("mysql:host=localhost;dbname=university", "root", "");
    $query = "SELECT * FROM ".$name;
    $rows  = $db->query($query);

    foreach ($rows as $row)
    {
        foreach ($row as $key => $value)
        {
      print ($key.":".$value."<br>");
        }
    }
}

And this is the output I get:

FM_ID:1234
0:1234
LAST_NAME:
1:
FIRST_NAME:
2:
OFFICE:Bliss 200
3:Bliss 200

Answer 1

try using

$sth = $db->prepare($sql);
$sth->execute();

$rows = $sth->fetchAll(PDO::FETCH_COLUMN);

instead using query

Answer 2

Im not sure if this would fix your problem but try something like this

$result_query = $db->query($query);
while($row = $result_query->fetch(PDO::FETCH_ASSOC)))
{

}
