How can the assignment operation affect the return value in PHP functions?

When using assignment operations within a PHP function, the return value can be affected if the assignment operation changes the value of the variable that is intended to be returned. To avoid this issue, make sure to return the variable before any assignment operations are performed on it within the function. 

function exampleFunction() {
    $returnValue = 10;
    
    // Perform some operations
    $returnValue += 5;
    
    return $returnValue;
}
