阅读完SQL注入攻击后,我只是在编辑搜索脚本。我正在尝试使用PDO而不是常规的mysql连接从脚本中获得相同的功能。因此,我一直在阅读有关PDO的其他文章,但不确定。这两个脚本会提供相同的功能吗?
使用PDO:
$pdo = new PDO('mysql:host=$host; dbname=$database;', $user, $pass); $stmt = $pdo->prepare('SELECT * FROM auction WHERE name = :name'); $stmt->bindParam(':name', $_GET['searchdivebay']); $stmt->execute(array(':name' => $name);
使用常规mysql:
$dbhost = @mysql_connect($host, $user, $pass) or die('Unable to connect to server'); @mysql_select_db('divebay') or die('Unable to select database'); $search = $_GET['searchdivebay']; $query = trim($search); $sql = "SELECT * FROM auction WHERE name LIKE '%" . $query . "%'"; if(!isset($query)){ echo 'Your search was invalid'; exit; } //line 18 $result = mysql_query($trim); $numrows = mysql_num_rows($result); mysql_close($dbhost);
我继续使用常规示例
while($i < $numrows){ $row = mysql_fetch_array($result);
从数据库创建匹配结果数组。我该如何使用PDO?
看一下PDOStatement.fetchAll方法。您也可以fetch在迭代器模式中使用。
PDOStatement.fetchAll
fetch
fetchAll来自PHP文档的的代码示例:
fetchAll
<?php $sth = $dbh->prepare("SELECT name, colour FROM fruit"); $sth->execute(); /* Fetch all of the remaining rows in the result set */ print("Fetch all of the remaining rows in the result set:\n"); $result = $sth->fetchAll(\PDO::FETCH_ASSOC); print_r($result);
结果:
Array ( [0] => Array ( [NAME] => pear [COLOUR] => green ) [1] => Array ( [NAME] => watermelon [COLOUR] => pink ) )
