PHP, originally created in 1994 as a ‘Personal Home Page’ tool, is a server-side programming language that can be used to solve numerous computing problems that a client-side language like JavaScript cannot. This highly useful text/reference presents key information needed to write your own online science and engineering applications, including reading, creating and manipulating data files stored as text on a server, thereby overcoming the limitations of a client-side language. This book focuses on those elements of the language - such as file input/output, arrays, built-in math functions, and user-created functions - that are essential for solving a wide range of scientific/engineering computing problems. It assumes a working knowledge of HTML, programming concepts, and JavaScript, C or a similar language. Features: • Offers a working knowledge of PHP, essential for server-side programming • Includes detailed code examples to guide the reader • Contains several complete applications that show how to take advantage of server-side programming capabilities • Extremely accessible, and ideal for self-study • Provides an author-supported supplementary website containing code examples (www.pages.drexel.edu/~brooksdr/DRB_web_page/BookCode/PHPBookCode.htm) • Directly addresses the needs of engineers, scientists and working professionals by explaining precisely those components of PHP required This concise applications-oriented text is an exceptional shortcut to learning the essentials of PHP and is ideal for self-study or course use. Dr. Brooks has authored several successful Springer titles, including: Problem Solving with Fortran 90 for Scientists and Engineers; C Programming: The Essentials for Engineers and Scientists; and An Introduction to HTML and JavaScript for Scientists and Engineers.
