In the years that I’ve been a web developer, I have written very few OOP PHP scripts. I just haven’t had the need to, and to be honest the whole OOP concept seemed like something I didn’t need to bother with. Why do I need to write a script in an object-oriented style and how will it help me? I had seen examples and read tutorials about OOP (some horribly bad and some really good) but never had any desire to try it myself until one day when I was working on a couple of different projects that both needed the same thing, pagination.
Pagination just means numbering pages. In the project that I was working on, I was retrieving large amounts of data from a MySQL database and realized that I would have to break the data up into pages for two main reasons, 1) there was so much data that it could hang the browser when it was loading and 2) from a user perspective (we still care about that right?) it was unruly to say the least. If I was returning 50,000 rows from a database query, I knew that I would need to slice that up into more manageable chunks. Now in the past, I had written basic pagination functions to handle this type of issue and sometimes copied and pasted functions from older scripts to cut down on development time, fixing and re-coding where necessary. But I realized that for this new project I could try to write a pagination class that I would be able to just plug into any script and have it do the pagination for me. I could write a pagination class that I could use for my projects and future projects, and learn OOP in the process. I love killing two birds with one stone.
