Are there any common pitfalls or mistakes to avoid when working with conditional statements in PHP, especially in error handling scenarios?

One common pitfall when working with conditional statements in PHP, especially in error handling scenarios, is forgetting to include an else statement to handle unexpected conditions. To avoid this mistake, always make sure to include an else block to catch any scenarios that are not explicitly accounted for in the if condition.

// Incorrect example without an else block
if ($condition) {
    // Handle the condition
}

// Corrected example with an else block for error handling
if ($condition) {
    // Handle the condition
} else {
    // Handle the error or unexpected scenario
}
