In PHP, variables are declared using the dollar sign ($) followed by the variable name. The syntax for declaring a variable in PHP is as follows:
$variable_name = value;Here, variable_name is the name of the variable, and value is the initial value assigned to the variable. For example, to declare a variable name with the value “John”, you would write:
$name = "John"PHP is a loosely typed language, which means that you do not need to specify the data type of the variable when declaring it. The data type is automatically determined based on the value assigned to the variable. For example, if you assign a string value to a variable, PHP will automatically create a string variable.
You can also use variables in PHP to store the results of expressions or function calls. For example, the following code declares two variables, a and b, and assigns them the values of 2 and 3, respectively. It then assigns the result of adding a and b to a third variable, c.
$a = 2;
$b = 3;
$c = $a + $b;
// c is now equal to 5Once a variable has been declared, you can access its value at any point in your code by referring to its name preceded by the dollar sign.
