Overview of this book

Do you want to build your own websites, but have never really been confident enough to turn your ideas into real projects? If your web development skills are a bit rusty, or if you've simply never programmed before, The PHP Workshop will show you how to build dynamic websites using PHP with the help of engaging examples and challenging activities. This PHP tutorial starts with an introduction to PHP, getting you set up with a productive development environment. You will write, execute, and troubleshoot your first PHP script using a built-in templating engine and server. Next, you'll learn about variables and data types, and see how conditions and loops help control the flow of a PHP program. Progressing through the chapters, you'll use HTTP methods to turn your PHP scripts into web apps, persist data by connecting to an external database, handle application errors, and improve functionality by using third-party packages. By the end of this Workshop, you'll be well-versed in web application development, and have the knowledge and skills to creatively tackle your own ambitious projects with PHP.

Errors in PHP

Errors and error handlers in software programming are a priceless concept that helps developers to identify failure points at the application compile-time or at runtime. They can signal different levels of severity. Hence, the script could emit a fatal error that causes the process to stop, it could emit warnings that point to possible misuse of the script, and it could also emit some notifications hinting at code improvements (for example, using an uninitialized variable in an operation). Therefore, errors are grouped in different levels, based on severity—fatal errors, warnings, notices, and debug messages, to name but a few. All these messages are usually collected to persistent storage, in a process called logging. The most accessible logging method is writing to a file on a local filesystem, and this is the default method for most (if not all) applications. These logs are read by developers to identify issues or look for other specific information, such as...
