In this PHP tutorial we'll introduce Exceptions in PHP.
In this PHP tutorial, you'll learn about the different exception classes that are available to you use in your PHP applications.
In this tutorial, learn about PHP's built-in magic methods: __toString()
, __get()
, and __set()
.
In this tutorial, learn how to use PHP's built-in interface ArrayAccess
and when you might want to use it.

In this tutorial, learn how to implement PHP's built-in interface IteratorAggregate
to loop over an object.
In this PHP tutorial, we'll introduce Traits in PHP and how you can utilize them to reuse your code.
In modern PHP, you're going to spend a lot of time working with other people's classes: via external libraries that you bring into your project to get things done faster. Of course, when you do that: you can't actually edit their code if you need to change or add some behavior.
Fortunately, object-oriented code gives us some really neat ways to deal with this limitation. In this tutorial, you'll learn a method called composition in which we'll create a wrapper class, which has some subtle advantages over using inheritance.

GuideAJAX is one of the main reasons to use a Javascript library such as jQuery. See how simple it is to perform a previously difficult task that required complex browser specific code to preform reliably and was prone to simple mistakes. Implement basic AJAX requests using jQuery's built in methods which make it extremely simple to send an asynchronous request to a server, gather the returned data, and insert it into the page.
Example code:
// AJAX Live Function
$('.content p').live('mouseenter mouseleave',
function() {
$(this).toggleClass('hilight');
}
);
// AJAX Example
$('.node_read_more a').click(function() {
var url = $(this).attr('href');
var link = this;
$.ajax({
url: url,
success: function(data) {
var $fullContent = $('#content-output .content', data);
var html = $fullContent.html();
$(link).closest('div.node').find('div.content').html(html);
$(link).hide();
}
});
return false;
});
In its short history, jQuery has revolutionized front-end web development, making it faster, easier, and more rewarding to write JavaScript – allowing easier selection and manipulation of HTML elements, and ensuring that scripts work across the ever increasing landscape of browsers and operating systems.
Nate Haug and Jeff Robbins show many hands-on examples demonstrating how to use jQuery's simple syntax to choose and manipulate HTML elements, traverse the document object model (DOM), and to attach event handlers which can react to user interaction with the page.
In this video, Jeff and Nate introduce themselves and the agenda for this series, including Selectors, Effects, and AJAX.
