What are some best practices for initializing static variables in PHP functions?

When initializing static variables in PHP functions, it is important to ensure that the static variable is only initialized once and retains its value across multiple function calls. One common approach is to use a static variable within the function and check if it has already been initialized before assigning a new value. This ensures that the variable is only initialized once and retains its value throughout the function calls. 

function myFunction() {
    static $initialized = false;
    
    if (!$initialized) {
        // Initialize the static variable here
        $initialized = true;
    }
    
    // Rest of the function code
}
