What is the best practice for running MySQL queries in PHP? Consider The risk of AQL injection.
Answers:
• Use mysql_query() and variables: for example: $input = $_POST['user_input']; mysql_query("INSERT INTO table (column) VALUES ('" . $input . "')");
• Use PDO prepared statements and parameterized queries: for example: $input= $_POST["user-input"] $stmt = $pdo->prepare('INSERT INTO table (column) VALUES (":input"); $stmt->execute(array(':input' => $input));
• Use mysql_query() and string escaped variables: for example: $input= $_POST["user-input"] $input_safe = mysql_real_escape_string($input); mysql_query("INSERT INTO table (column) VALUES ('" . $input. "')");
• Use mysql_query() and variables with a blacklisting check: for example: $blacklist = array("DROP","INSERT","DELETE"); $input= $_POST["user-input"] if (!$array_search($blacklist))) mysql_query("INSERT INTO table (column) VALUES ('" . $input. "')");
