Php code to import excel file to database

I want to import Excel data to my database using PHPExcel. Below is my code.

When I upload the excel file and submit the form, I can echo out the table but no data is being stored in the database, Can anyone please help me with this. Something is wrong with the SQL part or creating array of the data. Please anyone check and help me out. I can't use csv file, otherwise it would have been easier.
