What are common pitfalls when using If functions in PHP?

One common pitfall when using If functions in PHP is forgetting to use double equals (==) for comparison instead of a single equals sign (=), which is used for assignment. This can lead to unintended consequences and errors in your code. To avoid this issue, always double-check your conditional statements to ensure you are using the correct comparison operator. 

// Incorrect comparison using single equals sign
$number = 5;
if($number = 5) {
    echo "Number is 5";
}

// Correct comparison using double equals sign
$number = 5;
if($number == 5) {
    echo "Number is 5";
}
