PHP HELP, PHP TUTORIALS, OBJECT-ORIENTED PHP5 PROGRAMMING

In this second part of a two-part tutorial, you'll learn how to use closures in the development of an extendable template system. This system can be customized at will without struggling too much, thanks to the number of interfaces that it implements.

In this first part of a two-part tutorial, I develop a basic template system that can parse any type of closure assigned as a property of its view object(s).

In this conclusion to an eight-part article series on working with a computer's file and operating system with PHP, you'll learn about the functions used in combination with a PHP script to execute system-level programs. This article is excerpted from chapter 10 of the book Beginning PHP and PostgreSQL 8: From Novice to Professional, written by W. Jason Gilmore and Robert H. Treat (Apress; ISBN: 1590595475).

In this first part of a two-part tutorial, I use a somewhat contrived example to show why you should avoid coding static helper classes in PHP.

In this two-part tutorial, I show why the use of static helper classes can be detrimental to building robust and scalable object-oriented applications in PHP (though you should take into account that the concept is language agnostic). I also implement a set of instantiable, fine-grained validators, which can be easily tested in isolation, injected into the internals of other objects, and so forth.

In this seventh part of an eight-part article series on using PHP commands with your file and operating systems, you'll learn how and why to sanitize user input. This article is excerpted from chapter 10 of the book Beginning PHP and PostgreSQL 8: From Novice to Professional, written by W. Jason Gilmore and Robert H. Treat (Apress; ISBN: 1590595475).

In this sixth part of an eight-part series on working with the file and operating systems of a computer with PHP, you'll learn how to use PHP to write to a file and how to execute shell commands. This article is excerpted from chapter 10 of the book Beginning PHP and PostgreSQL 8: From Novice to Professional, written by W. Jason Gilmore and Robert H. Treat (Apress; ISBN: 1590595475).

In this fifth part of an eight-part series on working with file and operating systems with PHP, you'll learn how to read data from a file and move the file pointer. This article is excerpted from chapter 10 of the book Beginning PHP and PostgreSQL 8: From Novice to Professional, written by W. Jason Gilmore and Robert H. Treat (Apress; ISBN: 1590595475).

In this fourth part of an article series on working with the file and operating systems with PHP, you'll learn about file ownership and permissions, and the concept of a resource. This article is excerpted from chapter 10 of the book Beginning PHP and PostgreSQL 8: From Novice to Professional, written by W. Jason Gilmore and Robert H. Treat (Apress; ISBN: 1590595475).

In this second part of a two-part series on the ArrayObject class from the Standard PHP Library, you'll learn how to handle properties by means of an object syntax.

In this first part of a two-part tutorial, I demonstrate how simple it is to use the ArrayObject SPL class. This class permits you to easily access properties through an array syntax.

In this third part of an eight-part article series on using PHP to work with the file and operating system, you'll learn how to retrieve the size of a directory and find out a file's last access and modification times. This article is excerpted from chapter 10 of the book Beginning PHP and PostgreSQL 8: From Novice to Professional, written by W. Jason Gilmore and Robert H. Treat (Apress; ISBN: 1590595475).

In this second part of an eight-part article series on the tools PHP provides for working with the file system and operating system, we'll go over file types, links, and how to calculate file, directory and disk sizes. This article is excerpted from chapter 10 of the book Beginning PHP and PostgreSQL 8: From Novice to Professional, written by W. Jason Gilmore and Robert H. Treat (Apress; ISBN: 1590595475).

PHP as a language offers the programmer an excellent array of tools for handling file system input and output, as well as executing programs at the shell level. This article series will introduce you to these tools. It is excerpted from chapter 10 of the book Beginning PHP and PostgreSQL 8: From Novice to Professional, written by W. Jason Gilmore and Robert H. Treat (Apress; ISBN: 1590595475).

In this third part of a series on proxy objects, we'll create a simple service layer to add to our blog program. With this finished application, you'll see exactly how proxy objects can be powerful allies when you need to persist the entities of a domain model in a database.
