用PDO连接数据库是没问题的:

$dsn = "mysql:host=localhost;dbname=php_jquery_example";try {	$dbo = new PDO($dsn, 'root', '123');} catch(Exception $e) {	die($e->getMessage());}
Copy after login


预处理和绑定也没问题:
$sth = $dbo->prepare('SELECT event_id, event_title, event_desc    FROM events    WHERE event_id < ?');$sth->bindParam(1, $calories, PDO::PARAM_INT);
Copy after login


问题在执行上:
$sth->execute();
Copy after login

页面直接死掉,提示连接被重置
直接执行也会出现同样的问题:
foreach ($dbo->query('select * from events') as $row) { ...
Copy after login



用原始的方法连接和查询是没问题的.这是PDO执行SQL语句造成的,纠结了两天了.请高手帮帮我啊.....

下面是aparch错误日志打印出的信息:
[error] VirtualHost *:80 -- mixing * ports and non-* ports with a NameVirtualHost address is not supported, proceeding with undefined results

帮忙分析.

用pdo的好处是?????

PHP Warning: PHP Startup: Unable to load dynamic library '
不能加载动态库:php_mssql.dll php_pdo_mssql.dll

是不是因为缺少这两个库影响了页面的执行。

PHP Warning: PHP Startup: Unable to load dynamic library '
不能加载动态库:php_mssql.dll php_pdo_mssql.dll

是不是因为缺少这两个库影响了页面的执行。

应该不是,何况还是 sqlserver 的

用pdo的好处是?????

通用,更换数据库系统只需更换 DSN 串
当然 SQL 指令中也要顾及到差异

问题解决没有?
