PDO绑定参数在登台和管道服务器上静默失败

I am using WindowsXP machine for the PHP pages I am developing. I am using PDO to connect to MySQL backend. In my development environment it works just fine but it silently stops processing in my CentOS 5.5 testing server. After some debugging, I found that it stops exactly at '$stmt->bindParams' section.I am using WindowsXP machine for the PHP pages
