How to use PHP variables
Creating and Using Variables in PHP
Variables are used to store and manipulate values in PHP. They are defined using the dollar sign ($), followed by the variable name.
Syntax
$variable_name = value;
| Parameter | Description |
|---|---|
| variable_name | The name of the variable to be created. |
| value | The value to be stored in the variable. |
Here are some examples of using variables in PHP:
$name = "John Doe"; $age = 25; $salary = 1000.50; $isEmployed = true; echo "My name is " . $name . ", I am " . $age . " years old.";
Technical Details
| Technical Detail | Description |

| Variable Scope | The scope of a variable determines where it can be accessed within the program. Variables can be either local or global in scope. |
| Data Types | PHP supports a variety of data types, including strings, integers, floating point numbers, boolean values, arrays, and objects. |
| Variable Names | Variable names in PHP must start with a letter or underscore (_), and can only contain letters, numbers, and underscores. |
