在我的代码中,我试图使用 PDO 从我的数据库中获取数据并绑定参数,但我一直在获取空数组,这是我的代码:
try{
$pdo =new PDO('mysql:host=localhost;dbname=***', '***','***');
$pdo->setAttribute(pdo::ATTR_ERRMODE,
pdo:: ERRMODE_EXCEPTION);
$pdo->query('set names "utf8"');
}
catch (PDOException $e) {
die('error connectin database');
}
$table = 'products';
$column = 'id';
$niddle = '70';
$sql = "SELECT * FROM `{$table}` WHERE ";
$sql .= ":column LIKE :niddle";
$pre = $pdo->prepare($sql);
$pre->bindParam(':column', $column ,PDO::PARAM_STR);
$pre->bindParam(':niddle', $niddle, PDO::PARAM_STR);
$result = $pre->setFetchMode(PDO::FETCH_ASSOC);
$pre->execute();
print_r($pre->fetchAll());
没有抛出异常,可能是什么问题?
