Static Variable | Static Variable in Php | Static Variable Example with details
Variables are the basic structure of a programming language. So in this article, I will discuss with details on topics of Static Variable, Static Variable in Php, Static Variable Example, and much more.

Memory is a place where we save the data which we need for the program. We save temporary data these are data containers that value change time by time. In this article, I will discuss the PHP static variable. What I will cover in this article is why we need variables in the PHP language. How to make PHP variable? What are the rules of making variables in the PHP programming language? I will take the example of variable declaration. Assign the value to PHP variables. Some examples of variables in the PHP script, and explanation of PHP script. Also, see How to comment in PHP
Echo (5 + 2 ) ;
Its answer you know that it will be 7
Now I have more two numbers 3 and 6 or 9 and 20 and more numbers.
What will we do? Will we change our code for each number change?
See the example first I will do but these will not be effective for long code
Echo ( 3 + 6 ) ;
Echo ( 20 + 9 ) ;
In these cases, we need variables to solve these problems.
First of all we put $ sign then give a variable name.
The variable name may be on letters small or capital a-z A- Z numbers 0-9 and _ underscore means you cannot use space in variable name in PHP.
Your variable name may start from letters or _ underscore
The variable should not exceed 30 character limits.
$a_variable;
$_1234;
It means that we make space for save some value.
When we make space it’s called variable declaration. After this step we can assign value to our variable.
= is assignment operator it assigns value to variable whatever have in front of the variable.
$num_1 = 50;
$num_2 = 100;
$sum = $num_1 + $num_2;
Echo “sum is: “. $sum;
? >
The output of the program will be
Sum is: 150
I assign values to these variables
After assigning the value to these $num_1 and $num_2 variables
At second last step I make a new variable $sum and assign the both $sum_1 and $sum_2 variable with addition sign between them. This will add these two variable and assign the total of these variables to $sum variable as a result.
$sum = $num_1 + $num_2 these will add both first variables and assign value to $sum variable
At the end I print the $sum with echo statement. In this echo statement you are seeing a dot . what does this do? When we combine two strings then we put dot . in these two strings. It is called concatenation. In this statement we use these two strings. “sum is:” and $sum variable connected and print it. And as a result we see
Sum is: 150
Why do we need Static Variable programming?
Consider if I am going to develop a program in PHP that will sum two numbers, if I don’t use variables then I will do like this.Echo (5 + 2 ) ;
Its answer you know that it will be 7
Now I have more two numbers 3 and 6 or 9 and 20 and more numbers.
What will we do? Will we change our code for each number change?
See the example first I will do but these will not be effective for long code
Echo ( 3 + 6 ) ;
Echo ( 20 + 9 ) ;
In these cases, we need variables to solve these problems.
Second example:
I want to develop a program that user will input his name and when click on the button then it will shows a well come message like this ( Well come Saeed Developer to our website ) at user name maybe change by the user name for example if it’s not a saeed developer then it maybe ALI or any other name. Here you need variable to solve this problem. It is called PHP static variableHow to create Static Variable in Php? Static variable in php
In the PHP programming language to make a variable is a very easy task.First of all we put $ sign then give a variable name.
The variable name may be on letters small or capital a-z A- Z numbers 0-9 and _ underscore means you cannot use space in variable name in PHP.
Your variable name may start from letters or _ underscore
The variable should not exceed 30 character limits.
Examples of Static Variable Example Declaration | PHP declare a variable without value
$a;$a_variable;
$_1234;
It means that we make space for save some value.
When we make space it’s called variable declaration. After this step we can assign value to our variable.
Assign value to variable types of Static Variable in Php
$a = “Saeed”;= is assignment operator it assigns value to variable whatever have in front of the variable.
Static Variable Example use php variable in string
< ? php$num_1 = 50;
$num_2 = 100;
$sum = $num_1 + $num_2;
Echo “sum is: “. $sum;
? >
The output of the program will be
Sum is: 150
More understanding about this PHP script php variable in string
First you can see I make two variables $num_1 and $num_2I assign values to these variables
After assigning the value to these $num_1 and $num_2 variables
At second last step I make a new variable $sum and assign the both $sum_1 and $sum_2 variable with addition sign between them. This will add these two variable and assign the total of these variables to $sum variable as a result.
$sum = $num_1 + $num_2 these will add both first variables and assign value to $sum variable
At the end I print the $sum with echo statement. In this echo statement you are seeing a dot . what does this do? When we combine two strings then we put dot . in these two strings. It is called concatenation. In this statement we use these two strings. “sum is:” and $sum variable connected and print it. And as a result we see
Sum is: 150
