JQuery get data from JSON array

You need to iterate both the groups and the items.
$.each() takes a collection as first parameter and data.response.venue.tips.
groups.items.text tries to point to a string. Both groups and items are arrays.

Verbose version:

$.getJSON(url, function (data) {

    // Iterate the groups first.
    $.each(data.response.venue.tips.groups, function (index, value) {

        // Get the items
        var items = this.items; // Here 'this' points to a 'group' in 'groups'

        // Iterate through items.
        $.each(items, function () {
            console.log(this.text); // Here 'this' points to an 'item' in 'items'
        });
    });
});

Or more simply

$.getJSON(url, function (data) {
    $.each(data.response.venue.tips.groups, function (index, value) {
        $.each(this.items, function () {
            console.log(this.text);
        });
    });
}); 

Paypal Integration With IPN handler in asp.net

Select distinct values from DataTable column asp.net

Method 1:
 
DataView view = new DataView(table);
DataTable distinctValues = view.ToTable(true, "id");


Method 2: 

You will have to create a class matching your datatable column names and then you can use the following extension method to convert Datatable to List

public static List<T> ToList<T>(this DataTable table) where T : new()
    {
        List<PropertyInfo> properties = typeof(T).GetProperties().ToList();
        List<T> result = new List<T>();

        foreach (var row in table.Rows)
        {
            var item = CreateItemFromRow<T>((DataRow)row, properties);
            result.Add(item);
        }

        return result;
    }

    private static T CreateItemFromRow<T>(DataRow row, List<PropertyInfo> properties) where T : new()
    {
        T item = new T();
        foreach (var property in properties)
        {
            if (row.Table.Columns.Contains(property.Name))
            {
                if (row[property.Name] != DBNull.Value)
                    property.SetValue(item, row[property.Name], null);
            }
        }
        return item;
    }

For Distinct Value

YourList.Select(x => x.Id).Distinct();

Install IIS 7.5 PHP & FastCGI for PHP on Windows 7

Why install IIS?

Obviously you want to design web sites on your local computer and test them before uploading to your web server.

Why install FastCGI and not ISAPI?

Up until php version 5.3 most web developers using php installed ISAPI 
From php version 5.3 on ISAPI is not longer supported. 
The alternative is to use FastCGI
Although there are many web sites complaining about this change ISAPI works well for a website with 0-20 users,
however FastCGI runs much faster under a heavy user load and equally as well with smaller loads.

This guide has been updated and rewritten as the easiest way to successfully Configure IIS 7.5 to work with FastCGI and PHP on Windows 7 is to use

Microsoft Web Platform Installer 2.0 from http://www.microsoft.com/web/Downloads/platform.aspx

Why?

The installer does all the hard work

No more downloading PHP then configuring the php.ini file

No more going into your Internet Information Services (IIS) Manager and adding a Handler Mapping FastCGI Module

No more going into your System Properties and setting up your Environmental Variables

No more spending endless hours surfing around looking for solutions that help you get it all working (it rarely happens first time)

Microsoft have done all the hard time consuming work for a change - miracles do happen.

NOTE: This install was completed on Windows 7 Ultimate 64 bit and works for 32 bit systems.

Congratulations! - you have now Installed, Configured & Tested IIS 7.5 & PHP & FastCGI

The next step is using databases such as MySQL and Interfacing it with PHPMyAdmin, links below

NOTE: This installation does NOT enable mcrypt by default - see link below

In PHPMyAdmin you will receive the following

PHPMyAdmin Error "Cannot load mcrypt extension. Please check your PHP configuration"
