What other potential pitfalls should PHP developers be aware of when working with conditional statements?

One potential pitfall for PHP developers when working with conditional statements is forgetting to use the correct comparison operators. Using a single equals sign (=) instead of a double equals sign (==) can lead to unintended consequences and logical errors in the code. To avoid this issue, always double-check the comparison operators in your conditional statements.

// Incorrect comparison using a single equals sign
$number = 5;

if($number = 10) {
    echo "Number is 10";
} else {
    echo "Number is not 10";
}
```

```php
// Correct comparison using a double equals sign
$number = 5;

if($number == 10) {
    echo "Number is 10";
} else {
    echo "Number is not 10";
}
