Are there best practices for handling negation in PHP conditional statements?

When handling negation in PHP conditional statements, it is important to use the correct syntax to ensure the logic is accurate. One common mistake is using the "!" operator incorrectly, which can lead to unexpected results. To handle negation properly, it is recommended to use parentheses to group conditions together and make the logic clear. 

// Incorrect way of handling negation
if (!($a == 1 && $b == 2)) {
    // Do something
}

// Correct way of handling negation
if (!($a == 1) || !($b == 2)) {
    // Do something
}
