Yielding values with keys. PHP also supports associative arrays, and generators are no different. In addition to yielding simple values, as shown above, you can also yield a key at the same time. The syntax for yielding a key/value pair is very similar to that used to define an associative array, as shown below. JSON data is created by nested key-value pairs where the value can be a number, string, Boolean, null, object or array. Two built-in functions are used in PHP to encode and decode JSON data. These are jsonencode and jsondecode. In this tutorial, you will learn how you can generate and parse JSON data in various ways using PHP. Previous: Write a JavaScript program to create an array of key-value pair arrays from an given object. Next: Write a JavaScript program to get a customized coalesce function that returns the first argument that returns true from the provided argument validation function. How can I add key value pairs to an array? In PHP arrays are actually maps, where the keys can be either integers or strings. You can create the single value. It takes any number of comma-separated key = value pairs as arguments. Array( key = value, key2 = value2, key3 = value3. ) The comma after the last array element is optional and can be omitted. This is usually done for single-line arrays, i.e. Array(1, 2) is preferred over array(1, 2, ). For multi-line arrays on the other hand the trailing comma is commonly used, as it allows easier addition of new elements at the end. Yielding values with keys.

Hi all,
Php Array Key Value Pair
The other day a colleague of mine asked me if I had a .NETversion of the C++ sample in How to generate key pairs, encrypt and decrypt data with CryptoAPI post. C++ sample calls CryptoAPI directly (and you know we can do the same thing in .NET through P/Invoke), but the idea was to use System.Security classes in order to get a pure .NET solution. The answer is yes, I have such sample, and here it is:
If you compare both samples you will see that .NET simplifies the task a lot. But sometimes we won't be able to do with System.Security classes exactly the same we can do with CryptoAPI. So don't forget about the API just yet!
I hope this helps.
Kind regards,
