//连接、查询
try {
$dbh = new PDO('mysql:host=localhost;dbname=test', $user, $pass);
foreach($dbh->query('SELECT * from FOO') as $row) {
print_r($row);
}
$dbh = null;//释放资源
} catch (PDOException $e) {
print "错误!: " . $e->getMessage() . "<br></br>";
die();
}
//执行删除操作，插入、修改与此类似，更改SQL语句即可
$count = $dbh->exec("DELETE FROM fruit WHERE colour = 'red'");
