What are some potential pitfalls when comparing strings in PHP?

When comparing strings in PHP, one potential pitfall is using the "==" operator instead of the "===" operator. The "==" operator compares the values of the strings, while the "===" operator compares both the values and types of the strings. This can lead to unexpected results if the types of the strings being compared are different. To avoid this issue, always use the "===" operator when comparing strings in PHP. 

$string1 = "10";
$string2 = 10;

if ($string1 === $string2) {
    echo "The strings are identical.";
} else {
    echo "The strings are not identical.";
}
