stdClass: Storing Data in an Object Instead of an Array
Create new object:
$phone = new stdClass;
$phone->id = “10″;
$phone->title = “Nokia 5800″;
$phone->make = “Nokia”;
Create new object from array:
$phone = array(
“id” => “10″,
“title” => “Nokia 5800″,
“make” => “Nokia”
);
$phone = (object)$phone;

Skype / Xampp Port Conflict – How to overcome the problem
XAMPP is a software package which installs a copy of the Apache Server, Mysql, PHP and Perl onto a Windows computer and allows for local development of PHP and Mysql scripts without the need for uploading onto your Hosting account to test for errors, etc. A really simple to install set of softwares for those who need it. The manual install of all of these softwares can be difficult, but the Installer supplied by XAMPP reduces the difficulty factor down to a single download and essentially a one-click install.
SKYPE is a software which allows using the Internet to make phone calls and also offers a Chat service within the same software package. Works well. For a small fee, you can also have Skype become your phone provider, somehow, I am not exactly certain how it all works but apparently it is cheaper than a land line and works for cell phones, too.
Now, the purpose of this Tutorial is to explain that I have had XAMPP installed for a couple of months now, and have never had any problems with it that weren’t my own doing, sort of. Like when you delete a folder and those scripts won’t run any more isn’t really a software issue, is it.
Recently, I have not been able to use the Apache Server on my machine and have been perplexed by why it didn’t work. I un-installed, downloaded a new version, re-installed, etc, several times, but nope, no go… Today it became an absolute neccessity that I test a script so I really needed the Xampp to be properly functioning, so away I go to the Google thing and try to find the problem.
Well… I have only had Skype for a couple of weeks now, and it works terrific, BUT, by searching out this problem, I discovered that Skype uses PORT 80 on the Computer as a secondary PORT for communicating with the Main Server. Guess which PORT Apache uses??? Right, PORT 80… CONFLICT…
The fix is as simple as firing up Skype, selecting TOOLS > OPTIONS > Connections and un-checking the use of PORT 80 as an alternative port for incoming calls. Then close and re-open Skype. Simple, easy and quick.
So save yourself a bunch of headaches and if you have an Apache Server installed and also want Skype to run along side it, this is the fix…

Access Apace folder with Virtual directory port
1. Open the “httpd.conf” file
2. Add the below code at the end of file.
Listen 82
<VirtualHost localhost:82>
DocumentRoot C:/xampp/htdocs/test
<Directory “C:/xampp/htdocs/test”>
allow from all
Options +Indexes FollowSymLinks +ExecCGI
</Directory>
</VirtualHost>
3. Save the file and restart the Apache and enjoy with port.
4. Output is:
http://localhost/test/ or http://localhost:82
In the above ex:
Port: 82
Virtural host: Localhost with 82 port. We can map any port number above the 80. Ex: localhost:85 [or] 127.0.0.1:85 [or] 192.150.0.12:85
Document root: where the port need to map. In the above example, we mapped the “C:/xampp/htdocs/test”. We also map the linux directory as “/var/www/html/test”.
Directory: same as Document root
httpd.conf path:
XAMPP: C:\xampp\apache\conf\httpd.conf
Fedora linux: /etc/httpd/conf/httpd.conf
WAMP: c:\wamp\Apache2\conf\httpd.conf
WAMP user please refer this link: http://www.dennisplucinik.com/blog/2007/08/16/setting-up-multiple-virtual-hosts-in-wamp/
You think you know jQuery?
Website: http://tutorialzine.com/quizzes/take/1/
What does the function $(‘.selector’) return?
Ans: A new jQuery object.
Why do we usually add our jQuery code to the document.ready event?
$(document).ready(function(){
// do something
});
Ans: The document.ready event is fired when the DOM is initialized, and we can access all the elements on the page with jQuery selectors. We use it because this is the earliest time in the loading of the page that we can execute jQuery code safely.
What do we use jQuery.noConflict() for?
Ans: To restore the ‘$’ to its previous, non-jQuery owner. This way we can have more than one JavaScript library on the page.
Why do we usually add the stop() method before calling animate()? – WRONG
Ans:
How can you tell if an element is currently being animated?
Ans:
if($(‘#myDiv’).is(‘:animated’)){
// do stuff
}
What is Sizzle?
Ans: An open source JavaScript library, that is embedded inside jQuery, and handles the CSS-like selection of elements from the DOM.
What is the difference between .width() and .outerWidth()?
Ans: width() returns the computed width of the element, while outerWidth() returns the width plus all the margins and paddings.
What does the filter() method do in the following line?
$(‘div’).filter(‘.nav’)
Ans: It sifts through all the divs and leaves only those which have the nav class.
How do you fetch the first span on the page, which has the class ‘green’?
Ans: $(‘span.green:first’)
What does the $(‘#myDiv’).hover() method do? – WRONG
Ans: It binds the functions you pass as parameters, to the mouseenter and mouseleave events.
What actually happens when we write something like this: – WRONG
$(‘#myDiv’).find(‘span’).addClass(‘color’,'red’).width(200);
Ans: The dollar function creates a new jQuery object. Every method from then on returns that same object modifying it if necessary. This is called chaining.
If you want to make the #myDiv element 200px wide and 100px tall, can you do this:
$(‘#myDiv’).width(200).height(100);
Ans: Yes you can. When acting as setters, width and height return the jQuery object.
What does the end() method do in this chain? – WRONG
$(‘#myDiv’).find(‘span’).hide().end().addClass(‘.spansHidden’);
Ans: It restores the jQuery object to the state it was before being modified by find(‘span’). This way .addClass(‘.spansHidden’) is applied directly to #myDiv.
Which of the snippets below creates a new div and appends it to the first span on the page?
Ans:
$(‘<div>’,{
html:”This is a new <b>div</b>”
}).appendTo(‘span:first’);
Why doesn’t this work:
$(‘p’).click(function(){
this.html(‘clicked!’);
});
Ans: All event listening functions are passed the element, and not the jQuery object. For this to work, the second line has to become $(this).html(‘clicked!’);
What is the difference between – WRONG
$(‘#myDiv’).bind(‘click’,function(){
// do something
});
and
$(‘#myDiv’).click(function(){
// do something
});
Ans: There is no difference. They do the same.
Can we do this: - WRONG
$(‘#myDiv’).bind(‘myEvent’,function(){
// do something
});
Ans: Yes, we can bind custom events.
Which of the snippets below can listen for events on elements that are yet to be created?
Ans:
$(‘div.green’).live(‘click’,function(){
// do stuff
});
$(‘#myDiv’).trigger(‘click’);
Ans: It simulates a click on the element and runs all the event handlers associated with it.
Which of the below is equivalent to - WRONG
if($(‘#myDiv’).hasClass(‘purple’)){
// do stuff
}
Ans: if($(‘#myDiv’).is(‘.purple’)){
// do stuff
}
Why do we add a return false here?
$(‘form.contact’).submit(function(e){
// submit the form via AJAX
return false;
});
Ans: return false prevents the web browser from submitting the form and reloading the page.
What does the serialize() method do in the following line? - WRONG
$(‘#myForm’).serialize();
Ans: It fetches the names and values of all the input fields contained in the form, and generates a URL encoded string representation, ready to be submitted via AJAX or appended to a URL.
What does the $.get() jQuery function do?
Ans: It fires a GET AJAX request.
What does $(‘#myDiv’).load(‘page.html’) do?
Ans: It fires an AJAX request, fetches the result of page.html as text, and inserts it into the div.
What is the difference between $(‘#element’).remove() and $(‘#element’).detach()
Ans: remove() removes the element from the DOM along with any jQuery data such as event handlers, while detach() only removes the element from the DOM.

How to remove all “.svn” folders in Windows XP & Vista?
The application is really big with lots of features and all. But when I tried to copy the source code into beanstalk repository I came to see the “.svn” folders are already created in the application. Delete “.svn” folders in the project is a tedious process since I am using Windows Vista for development. If my operating system was Linux simple “rm” command with a regular expressionwill do. So I googled it for some help. I got really interesting tip to delete this folders. I would like to share it with you
The best thing they suggest is creating a registry file (filename.reg) and execute [create a text file named svndelete.reg and insert the code snippet below there after double click on the file that will add registry entry] the code snippet below. Once reg file is executed you will get a menu item called “Delete SVN Folders” in the context menu. Just right click on click on the “Delete SVN Folders” will delete all “.svn” folders in the directories recursively.
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Folder\shell\DeleteSVN]
@=”Delete SVN Folders”
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Folder\shell\DeleteSVN\command]
@=”cmd.exe /c \”TITLE Removing SVN Folders in %1 && COLOR 9A && FOR /r \”%1\” %%f IN (.svn) DO RD /s /q \”%%f\” \””
