Are global variables considered best practice in PHP programming?

Global variables are generally not considered best practice in PHP programming as they can lead to various issues such as naming conflicts, difficulty in tracking variable changes, and security vulnerabilities. It is recommended to use local variables within functions or classes to encapsulate data and reduce dependencies on external factors. 

function exampleFunction() {
    $localVariable = 'This is a local variable';
    // Use $localVariable within this function
}
