How can you use an array to handle a variable number of variables passed to a method in PHP?

When dealing with a variable number of variables passed to a method in PHP, you can use an array to handle these parameters. By passing an array as a parameter, you can easily iterate through the elements and process them accordingly. This allows for flexibility in the number of variables passed without having to explicitly define each one in the method signature. 

// Example of using an array to handle a variable number of variables passed to a method
function processVariables(array $variables) {
    foreach ($variables as $variable) {
        // Process each variable as needed
        echo $variable . "<br>";
    }
}

// Usage
$vars = ['Variable 1', 'Variable 2', 'Variable 3'];
processVariables($vars);
