Is it common to encounter issues with if statements in PHP code?

It is common to encounter issues with if statements in PHP code, especially when dealing with complex conditions or nested if statements. One common issue is forgetting to use double equals (==) for comparison instead of a single equals sign (=), which is used for assignment. To solve this issue, always double-check the condition in your if statement to ensure it is correctly comparing values.

// 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";
}
