The relational database management system (RDBMS) is a database management system based on the relational model. Today most databases use it. MySQL is one of them. Along with PHP, we need to know about MySQL for one reason. MySQL is a central component of the LAMP open-source web application software stack. LAMP is an acronym for “Linux, Apache, MySQL and Perl/PHP/Python”. How important MySQL is? Well, it really needs no introduction. Many popular applications, such as WordPress, Drupal or Joomla use it. Many high scale websites including Google, Facebook, Twitter, Flickr and YouTube draw on it. Since 1980s it has been a common practice for storage of information in databases. Databases are used for different types of applications; from financial records to personal data – it’s much easier to implement and administer. RDBMS like MySQL maintains a clearer division between the database model and the application.
In this video tutorial, I have shown how Reflection API works in PHP 7. Since many PHP frameworks such as Laravel 5.7 uses this Reflection API and Dependency Injection concepts, I think, understanding this major concept is essential for your PHP training.
Object Oriented Design Patterns in PHP 7
Gang of Four!
How about starting this discussion by quoting from them?
Their famous book “Design Patterns, Elements of Reusable Object-Oriented Software”; and they are Erich Gamma, Richard Helm, Ralph Johnson and
The book starts with this meaningful statement— “Designing object-oriented software is hard, and designing reusable object-oriented software is even harder. You must find pertinent objects, factor them into classes at the right granularity, define class interfaces and inheritance hierarchies, and establish key relationships among them.
Your design should be specific to the problem at hand but also general enough to address future problems and requirements. You also want to avoid redesign, or at least minimize it. Experienced object-oriented designers will tell you that a reusable and flexible design is difficult if not impossible to get “right” the first time. Before a design is finished, they usually try to reuse it several times, modifying it each time.
Yet experienced object-oriented designers do make good designs. Meanwhile, new designers are overwhelmed by the options available and tend to fall back on non-object-oriented techniques they’ve used before. It takes a long time for novices to learn what good object-oriented design is all about. Experienced designers evidently know something inexperienced ones don’t. What is it?”
This introductory paragraph ends with a question mark.
