Hi, Jason and Shahmat: I figured it out! The register_globals is turned off. To parse the id with this parameter off, I just need to judge whether $_GET["id"] is set or not. The problem is that I wrote the SQL statement as: $SQLstr="SELECT * FROM employees WHERE id=$_GET["id"]"; That's a wrong one. To solve this, I do the following (a naive one): $tid=$_GET["id"]; $SQLstr="SELECT * FROM employees WHERE id=$tid"; And it's OK. Thank you very much for your helps!
