How to Search for Data in Multiple Inputs with PDO?

[ImagjneAlex]

Friends, I have a contact application. It includes fields for Name, Department, and Extension Number. Currently, I can search using all of these fields with my MySQL codes. However, I need to switch to PDO. I am in the process of converting my MySQL codes to PDO. I have converted most of them, but I am stuck on the search functionality. I am able to search using a single input, but I am unsure how to search using the others. If anyone has any ideas or knowledge on this matter, could you please help me out?
