How can one ensure proper evaluation of function return values versus variable assignments in PHP?

When evaluating function return values versus variable assignments in PHP, it is important to use the correct comparison operators. To ensure proper evaluation, use the "===" operator to compare both the value and the type of the variables. This helps avoid unexpected type coercion and ensures accurate comparisons.

// Incorrect way of evaluating function return values versus variable assignments
$result = someFunction();
if ($result == true) {
    // This may lead to unexpected behavior if $result is not a boolean true value
}

// Correct way of evaluating function return values versus variable assignments
$result = someFunction();
if ($result === true) {
    // This ensures accurate comparison of both value and type
}
