It is very common to have the list exportable to save the data from the database to local machine. Doing this with online web list data is not that hard. We would like to recommend using phpExcel to get this work done. However, this tutorial not only introduce that library but also introduce how to using that library dynamically meaning that create your own library to work with the existing library. What does using that library dynamically really mean? To answer this question, let’s suppose there are 4 table lists in our website with different data like customerinfo, customerlog, songlist, and newslist. Therefore, using that library dynamically means having a standard php file containing our own library and be able to be used for all data list type by just identifying the list type.
