display selected fields from multiple mysql table

[g.sobhani]

hi, i'm new to php. i've got a problem.

I've 3 tables and table has following content

 

table 1

id  name  email  address  phone  execution_date  executor_name  web_address

 

 

table 2

id  name  email  address  phone  execution_date  executor_name  project_title

 

 

table 3

id  name  email  address  phone  execution_date  executor_name  reviewer

 

I want to export these table to and spreadsheet (.xls) with some criteria

 

a form will assign which data will published at the spreadsheet with these criteria

#all data can be exported from three tables

#some column can be selected from three tables

#some or all data can be selected from individual table

 

i've implement a script for this but it didn't meet my requirements. Can anyone help?

 

here is my script

 

<?php
