What are the potential pitfalls of not properly managing variable scope in PHP scripts?

Not properly managing variable scope in PHP scripts can lead to conflicts, unexpected behavior, and security vulnerabilities. To avoid these pitfalls, it's important to define variables within the appropriate scope, such as using global, local, or static variables depending on the desired behavior. 

function myFunction(){
    $localVariable = "I am a local variable";
    echo $localVariable;
}

myFunction();
