Explain Function Variable Decalartion Iin Php With Syntax And Program
In PHP, function variables are declared within a function's scope, enabling the storage and manipulation of data specific to that function, which helps in modular and reusable code. The syntax involves defining a function with the `function` keyword followed by the function name and parentheses, then declaring variables inside the function body. For example:
```php
<?php
function greet() {
$message = “Hello, World!”; // Local variable within function
echo $message;
}
greet(); // Calls the function
?>
```
Declaring variables inside functions is useful for encapsulating data, avoiding conflicts with variables outside the function, and maintaining clean, organized code, especially when performing specific tasks or computations within a program.
