Installing and Testing Wampserver Introduction 1

Confidently, you have now downloaded and installed Wampserver. This will provide you a server on your personal PC (Windows users), everywhere you can test your scripts. If you haven't yet dowloaded the Wampserver software, you can download it here:

you should have an new icon in the bottom right, where the clock is:

Click on localhost, though, and you'll see this page appear: (Localhost just refers to the server running on your own computer. Another way to refer to your server is by using the IP address 127.0.0.1.)

Click the link under Tools that says phpinfo(). If all went well, you should be looking at the following page (The one below is a different php version, but don't worry about this - as long as you see something):

Nodejs Events

Events in Node.js The EventEmitter Object You can assign event handlers to your own events with the EventEmitter object. In the example below we have created a function that will be executed when a "scream" event is fired. To fire an event, use the emit() method. var events = require('events'); var eventEmitter = new events.EventEmitter(); //Create an event handler: var myEventHandler = function () { console.log('I hear a scream!'); } //Assign the event handler to an event: eventEmitter.on('scream', myEventHandler); //Fire the 'scream' event: eventEmitter.emit('scream');

But we can specify how many books he will be collecting. If you have five books to give him, then you do the "Answer" is like this: Answer is = 5 Books Ok, now going to the subject … you're studying PHP, so there's something missing. Two things, actually. First, your people (variables) need a dollar sign at the beginning (people are like that). So it would be this: $ books = 10 Examples 2 : try to do $books=10+20+30; What is your answer : answer must be 60 Example 3 : Test your mind Find the total books ? $english_book=10; ...
