This pattern is often used when trying to avoid polluting the global namespace, because all the variables used inside the IIFE (like in any other normal.They can be declared like any other variable. This is still quite tricky as most of the data elements require Ids and not the screen value.A class in C++ is a user-defined type or data structure declared with keyword class that has data and functions (also called member variables and member functions) as its members whose access is governed by the three access specifiers private, protected or public.By default access to members of a C++ class is private.The private members are not accessible outside the class they can be.

After this, we can assign any value to the variable we want. See below As you can see here we just need to define the variable name but for this, we use вЂ$вЂ™ symbol. First, we will see how to declare a global variable in PHP which can be accessed anywhere in the application.

For better understanding, we will see one example for the beginners to get more clarity of the global variable. So here we will discuss how to use them inside the function and how to declare them. As we have discussed earlier also that we just declare them like other variables, but in order to access them we need to follow some standard defined by the PHP. Also, these variables can be accessed from inside or outside of the function as well. This variable like any other variable in PHP.

Like any other programming language, it maintains the history of the global variable in an array. LetвЂ™s discuss some important points for the global variable in order to use them inside the application see below 1) Global ArrayIn PHP we use an array to access this global variable. By the use of this array, we can access this variable in and out of the script. In PHP, it maintains an array where it stores all the global variable that we defined in an application.

But once defined we are directly using them without the global keyword. For better understanding we will see one syntax to use them inside the function see below Global $demovar1, $demovar2, $demovar3, $demovar4 As you can see in the above example that we are using a global keyword to access the variable inside the function. After mentioning the variable name with this we can use them throughout the function without the global keyword as well. LetвЂ™s see one practice example for better understanding see below $GLOBALS 2) Access them inside the function in PHPIF we want to access the global variable inside any function or method then we can use the вЂglobalвЂ™ keyword. Inside this bracket, we have to give the variable name that we want to access. LetвЂ™s see the syntax for this see below As you can see in the above lines of code we are using вЂ$GLOBALSвЂ™ keyword to access them followed by the square bracket.

The advantage of using a global variable is that we may require logged in user names everywhere in the application so by the use of it we can store them into the global variable and that can we easily accessed while application. To access the variable directly from the array we have to use вЂ$GLOBALSвЂ™ keyword followed by the variable name like we access an array by its index. But keep in mind that the variable should be unique otherwise it will override like any other programming language. We access the global variable inside nay thing by using the global array which maintains all the variables defined in the application. This variable can be accessed inside or outside of the functions well but to access them we have to вЂglobalвЂ™ keyword. IF you want to define a global variable you can use вЂ$вЂ™ followed by the name of your variable.

We just need to follow some standards while accessing them inside the function. Example #1In this example, are trying to access the global variable from the function using an array.Echo $demovar1.$demovar2.$demovar3.$demovar4.$demovar5 By using the global variable we can access variables in our whole application these are useful when we have to use same value in the whole application for example username, password and so many other details depend on the requirement.
