echo $info['p_id'];

$pl_1 = $player[0];

$pl_10 = $player[9];
echo $player[0]; //notice here
echo $pl_1; //notice here
?>
<table>
$query = $con->prepare("SELECT role,name,value FROM players WHERE p_id = '".$pl_1."'");
// notice here
$query->execute();
while($result = $query->fetch(PDO::FETCH_ASSOC))

echo "<tr>";
echo "<td>".$result['role']."</td>";

当我回显 $info 数组时,它工作正常,但是当我回显 $player 数组或 $pl_1 变量或 $result 数组值时,会出现通知...数组到字符串的转换并且 o/p 不显示。为什么?
