This is commonly seen in apps like Twitter, Facebook, Trello, Quora and many more. Activity Streams - streams of friend or project activity.Notifications - when something a user is interested in becomes available or changes.It’s also highly beneficial to sports, betting and analytics. Realtime Stats - The technology was first used in finance to show stock exchange information so it’s no surprise that the technology is now used more than ever.Real-time Web technologies are making it possible to build all sorts of engaging functionality, leading to improved user experiences. How are Real-Time Technologies being used? It can be a massive resource saving to the server and client, with the latter being particularly important for mobile devices where battery power is extremely valuable. Older solutions could only achieve two-way communication using two connections so the fact the WebSockets use a single connection is actually a big deal. WebSockets represent a stardardized API and protocol that allows realtime server and client (web browser) two way communication over a single connection. Our prayers have finally been answered with HTML5 WebSockets. But this didn’t remove the fact that there was a requirement to be able to do this in a cross-browser and standardised way. WebSocketsĮarlier on I stated that previous solutions to let servers instantly push data to Web browsers were considered “hacks”. Facebook, with it’s real-time wall (and later other realtime features) and Twitter with it’s activity stream centric user interface, and focus on conversation, demonstrated how Web applications could be highly engaging. Although applications had become more dynamic through the use of JavaScript, the experiences were seldom truly interactive.
Increased User ExpectationsĪs more users moved to using applications such as Twitter and Facebook, and the user experiences that they deliver, their perception of what can be expected from a Web application changed. This idea of Publish/Subscribe is core to the real-time Web, especially when building Web applications. There are now platforms that not only make our data instantly discoverable but also instantly deliver it to those who have declared an interest. Gone are the days where we have to wait an eternity for Google to find our data (blog posts, status updates, images). Social media, and specifically Twitter, has meant that more and more data is becoming instantly available. In my opinion there are a number of factors that have moved real-time Web technologies to the forefront of Web application development. In 2006 these solutions were given an umbrella term called Comet, but even with a defined name the solutions were still considered hacks. These initial solutions were classed as “hacks”.
PHP COMMENT SOFTWARE
They were mainly used by companies building software targeted at the financial services sector or in Web chat applications. Why Should We Care About The Real-Time Web?Īlthough the Real-Time Web is a relatively recent mainstream phrase, real-time Web technologies have been around for over 10 years.
PHP COMMENT HOW TO
In this tutorial, I’ll show how to convert a basic blog commenting system into a real-time engaging experience where you’ll see a comment made in one browser window “magically” appear in a second window.
You could match the first ones with : $matches_slashslash = array() comments which start by // and go to the end of the lineĬonsidering you have these two lines first : $filePath = '/home/squale/developpement/astralblog/website/library/HTMLPurifier.php'.To match comments, you have to think there are two types of comments in PHP 5 :
