What are the potential consequences of using func_get_args() directly as a parameter in PHP functions, and how can this be avoided?

Using func_get_args() directly as a parameter in PHP functions can lead to potential security vulnerabilities, as it allows for arbitrary arguments to be passed to the function. To avoid this, you can use the func_get_args() function to retrieve the arguments and then validate and sanitize them before using them in your function.

function exampleFunction() {
    $args = func_get_args();
    
    // Validate and sanitize arguments here
    
    // Rest of the function logic
}
