Powershell arrays are used to store a collection of elements in a single variable. These elements do not to be the same type and declared in different ways. Create Array We will start with a simple example where we will create an array by providing the items. Items will be delimited with the comma. The array definition will start with a dollar sign $.

We can see that different...
Loops are an important part of the programming languages. For and While loops are used for decades in different programming languages. Foreach provides similar functionality with a more elegant way by iterating over the given list. In this tutorial, we will examine foreach in different programming languages like PHP, JavaScript, Java, C# and Python. PHP Foreach PHP provides foreach in order to iterate over given arrays. There is two main usage...
[rps-include post=6522] We have used single value variable types up to now. But the real world problems may need different solutions and variables then those. We generally define,use multiple and a lot of values. Defining one by one variable is not a practical solution for these situations. For example we want to store 5 students names in a single variable. We call these as arrays. Arrays can hold multiple values....
[rps-include post=6557] Arrays are different from primitive types like integer,chars. Arrays provides fixed length sequential data. All of the data is same type. We can think array like a same type list. Arrays uses indexes to specify specific item in array. Declaring Arrays There is two must do to define array. One is the type of the array and second is length of the array. Basic syntax of defining array...
[rps-include post=6557] String is multiple characters added together. “Hi Poftut” is a string. Actually C do not direct String type but character type is used to store single and multiple characters. Character Character types is defined with char keyword. Single character will hold 1 byte in the memory. Character type normally hold ASCII characters but third party libraries provides support for different character types like UTF-8, UTF-16 etc. char mychar=’a’; String...
[rps-include post=6835] Creating variable is easy and very useful to make simple applications. If the variable count goes up managing variables becomes pain. Think that if the variables count is higher than 100 how easily can be created, assigned. There is a simpler usage for multiple variables. It is called array. An array is a variable that holds more than one value with similar types. For example we have script...
While programming we generally need to use multiple even several hundred variables of single type. Should we define one variable for each value? No. We can use arrays which can hold multiple values in a single variable. An array is string of values. So it gives the flexibility to store more than one data into single variable. An array can be defined like below.

JSON or Javascript Object Notations is a RFC standard which is used to define complex data types with number 7159. JSON became very popular in recent years because of its compatibility and simplicity. Python have rich support web applications and popular framework Django is developed with python too. So we generally need to use JSON with python web applications. In this tutorial we will look how to cope with JSON data...
There are different ways to randomly select elements of an array in PHP. But recurring elements are biggest problem most of them. Here the clean and PHP library supported solution for this. We will use shuffle() function which will change the positions of the given array. Shuffle Example shuffle() function accept only single parameter which is the array we want to shuffle. shuffle() function will return shuffled array. In this example we will...
