How This Book Is Structured The chapters in this book are laid out in a logical order, explaining basic programming concepts first, then building on those concepts in later chapters when covering more advanced topics. As a general rule, each chapter builds on the knowledge gained in previous chapters, so you shouldn’t need to jump around the book too much. However, if you’re already familiar with some of the basic ideas of PHP, you’ll find you can easily dip into later chapters if you’re looking for specific information.
3 also introduces a goto operator that you can use to jump directly to a line of code within the same file. ) For example: goto jumpToHere; echo 'Hello'; jumpToHere: echo 'World'; Use goto sparingly — if at all — as it can make your code hard to read, as well as introduce thorny programming errors if you’re not careful.
