PHP Iterator

Dejan Bosanac PHP arrays are generally a very powerful object container. But still, we can easily add a little more fuel to them. Imagine an iterator object as a kind of wrapper around our arrays. What we will try to accomplish here is to create unique interface for traversing arrays and to add a little more control over how our objects are created and finally, to support lazy loading. Interface Iterator has a very simple and many times seen interface.

Security for the administration page will not be addressed directly here, but it is recommended that some form of access restriction is used. If the page is being displayed via an Apache web server, the .htaccess file can be...

PHP-HTML Templates: A New Working Relationship

By Wee Lep From preface of the PHP manual, the following states the definition of PHP scripting: "PHP is an HTML-embedded scripting language. ... The goal of the language is to allow web developers to write dynamically generated pages quickly." The phrase "HTML-embedded scripting language" reminds me of my days in "dot-coms" ("dot-gones" for now). I was involved in the development of corporate portal sites. My working counterparts were mainly webpage and graphic designers with little or...

Using PHP As A Shell Scripting Language

Darrell Brogdon As most of us already know, PHP is the best language for developing dynamic web pages available today. Not many people are aware that it can be used as a shell scripting language as well. While PHP as a shell script isn't as robust as Bash or Perl it does have definite advantages, especially if you're like me and are more proficient in PHP than you are in Perl. The requirements for using PHP as a shell language is that you must compile PHP as a CGI binary instead of as...

Now, combined with the PHPEclipse plugin, Eclipse offers a world-class development environment for PHP applications. This article...

Using Sockets in PHP

Armel Fauveau PHP can open sockets on remote or local hosts. Here is a hands-on example of using such a socket: getting connected to a Usenet News Server, talking to this server, and downloading some articles for a precise newsgroup. Opening a socket in PHP Sockets are opened using fsockopen(). This function is both available in PHP3 and PHP4. It uses the following prototype : int fsockopen (string hostname, int port [, int errno [, string errstr [, double timeout]]]) For the Internet...

Best Practices: PHP Coding Style

Tim Perdue One of PHP's greatest strengths can also be a great weakness in the wrong hands. I'm talking about its forgiving nature. One of the reasons why PHP has become so wildly popular is because it lets very inexperienced web developers build powerful applications without much planning, consistency, or documentation. Unfortunately, that means an awful lot of PHP code out there is sloppy, hard to read and impossible to maintain. I know because I've written a lot of it ;-). To address...

Using cURL with PHP

Ian Gilfillan cURL is one of the most powerful PHP extensions. It stands for Client URL, and allows you to communicate with other servers using a wide range of protocols. Perhaps that sounds fairly uninteresting, but give it some more thought. Other servers and other protocols? At some stage in a novice developer's career, there comes a time to break out of the local server, and cURL is the first thing you should consider. I first used cURL for quite a simple task - processing a file on...

Classes and PHP

Rod Kreisler The hardest concept I've tried to understand since beginning to use PHP was that of classes. I'd never used a database engine but learning to use MySQL, at least for the more basic functions, was a breeze. Having never used OOP before, classes were novel as well, but understanding the theory and why it was useful escaped me. I knew they must be powerful as "everything" is programmed using OOP, but for the life of me, although I thought I understood the mechanics, I couldn't...

Creating Dynamic Images with PHP

Rasmus Lerdorf Many people do not realize that PHP can be used to create non-HTML data. This is especially useful for creating images on the fly. It could be simple bar graphs that display data from a database, or even simpler, just a way to create graphic buttons on the fly. When I am putting up a site quickly, I find that it is a waste of my time to sit and fiddle with an image editor to create nice-looking graphical buttons and menus. Instead I will pick a nice TTF font and use the...

Date Manipulation in PHP

Allan Kent I was sitting writing a kind of helpdesk call management program in PHP and found that I needed to work out how much time had elapsed since somebody had last bothered to contact the client about their problem. In the past, when I used to use ASP, the solution was simple - ASP has a command called DateDiff which takes two dates and can tell you how many seconds has passed between them, how many days, months and so on. After scouring the PHP manual for a while I decided that...

Getting Started with PHP/Ming

Iman S. H. Suyoto One day, I found a site about Ming, a SWF output library and PHP module. Somehow, it attracted me, and gave me a driving force to try it immediately. I tried to read quickly to find things I'd be able to download. I downloaded the source code, the examples, and the precompiled PHP module. When I don't have extra time, sometimes I think, "why compile it myself if someone else has compiled it for me?" Therefore, I fetched the compressed file, uncompressed it into a...

PHP and Working with Databases (for the Lazy Sod)

Database Abstraction and Atomic Operations and Classes Explored By Justin Vincent The Lazy Sod Maybe it's just me, but after building database driven websites in PHP for the past six years I am starting to get more than a little tired of repeating myself. What I mean to say is... how many times, on how many different projects, and with how many different databases do I have to write something along the lines of:

On User-Defined Timezones in PHP

By David Whittington and Luke Ehresman ABSTRACT PHP provides some nice date manipulation functions that work very well in combination with each other. However, they only handle dealing with the server's timezone. Adding the feature for shifting dates to a user-defined timezone can be a very unpleasant experience, as we know first hand. In this article, we discuss the problems we encountered, and present our solution. Introduction We work for a software development company, CommNav , who...

Replacing Perl Scripts with PHP Scripts

By Jayesh Jain Introduction With the introduction of version 4.2, PHP has started supporting a new SAPI (Server Application Programming Interface) called CLI (Command Line Interface). This facility was introduced to help developers create small shell applications (scripts) with PHP. So, now you can kiss Perl goodbye forever. The CLI SAPI was released for the first time with PHP 4.2.0, but was still experimental back then and had to be explicitly enabled with --enable-cli when running...

Using the Manual at PHP.net

Jeffery Vaska It might seem ridiculous to write about something as simple as how to use the online manual at PHP.net , but for two reasons I believe it's not really so absurd. When I first wandered into PHP territory I tried to use 'the manual' . While being the most comprehensive resource available I was unable to deal with it. I could not find the help I needed nor was I able to understand much of what it was telling me. I asked a friend to provide me with a reading list and I'm still...

How To Document Your PHP Classes

stefano Locati So you've read about how Object Oriented programming can help you with your big web projects and you've started it using with PHP? If you've already written a handful of classes to implement a site and you're methodic, then you should have written some documentation about them. But If you're just messy like me you've just written some comments within the classes' source and no other documentation. Without documentation it's difficoult to remember methods' names and the...

A Practical Approach to Object-Relational Mapping in PHP

by Kieran Mathieson PHP applications use various technologies, like HTML, relational databases (RDB), JavaScript, object-oriented programming (OOP), and so on. Most of them work well together. For instance, PHP code can easily write JavaScript, JavaScript can use a browser's document object model (DOM) to change HTML, etc. OOP and RDB don't fit together quite as well. When programmers write code mapping PHP classes to RDB tables, they need to make sure the classes do not become too...
