Tutorial PHP Class For Simple CRUD with PDO For Beginners

Seegatesite.com – Step by step tutorial create php class for simple CRUD with PDO. using PDO in PHP turned out to be much easier and simpler than with mysql extention. Starting from PHP5 upgrade to Php7, requires me to learn more about the PHP PDO extension. Php7 no longer supports MySQL extension, so inevitably have to switch to PDO. Sometimes when we hear the word PDO Class, we give up yet. Apparently, using the PDO is much more comfortable and effective. I will share a tutorial php class for simple crud with pdo. To be clear, I will discuss a little bit in advance what is the PHP PDO.

Definition of PDO (PHP Data Objects)

PDO (PHP Data Objects) is a universal interface that is provided by PHP to “communicate” with the database server. You mean the term “universal interface” here is that the PDO is not tied to specific database application. If today we use the MySQL database and later want to migrate using PostgreSQL, we only stayed change how the initial call PDO and all the existing code can be directly used for the new database (this is one advantage phenomenal PDO).

Technically, if using PDO, it is not connected directly to the database, but only as an “interface”. PDO concept can be described as follows:

PDO working with a method called “a data-access abstraction layer”. That is, any type of database server that used, written PHP code will remain the same. PDO provides “abstraction layer” to communicate with the database server.

To use the PDO, we have to access it using objects. PDO does not provide a way of writing style such procedural or mysql mysqli extension (It makes us afraid to try PDO). But here I will share how I make php PDO class to use easily. I once wrote an article about Connect Bootstrap Login Form and MySQL with PDO, but how to use PDO I have not discussed in full.

Let’s start the tutorial PHP class to create crud with PDO extention.
