pdo防范sql注入的方法:
在对应的文件中添加以下代码:
$dbh = new PDO('mysql:dbname=dbtest;host=127.0.0.1;charset=utf8', 'user', 'pass');
$dbh->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
代码使用实例:
$dbh = new PDO("mysql:host=localhost; dbname=demo", "user", "pass");
$dbh->setAttribute(PDO::ATTR_EMULATE_PREPARES, false); //禁用prepared statements的仿真效果
$dbh->exec("set names 'utf8'");
$sql="select * from test where name = ? and password = ?";
$stmt = $dbh->prepare($sql);
$exeres = $stmt->execute(array($testname, $pass));
if ($exeres) {
while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) {
print_r($row);
}
}
$dbh = null;
