我对 PDO 还很陌生,想知道下面的查询是否可以避免 SQL 注入。如果是这样,我将在整个站点中使用此方法。
// make connection to DB
$db = new PDO('mysql:host='.$dateBaseHost.';dbname='.$dateBaseName, $dateBaseUsername, $dateBasePassword);
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
//simple query and binding with results
$query = $db->prepare(" SELECT * FROM `profile` WHERE `fullname` = :fullname ");
$search = (isset($_GET['search']) === true) ? $_GET['search'] : '' ; // ? : shorthand for if else
// bind parameters - avoids SQL injection
$query->bindValue(':fullname', $search);
//try... if not catch exception
try {
// run the query
$query->execute();
$rows = $query->fetchAll(PDO::FETCH_ASSOC);
echo '<pre>', print_r($rows, true),'</pre>';
}
catch (PDOException $e){
sendErrorMail($e->getMessage(), $e->getFile(), $e->getLine());
}
