Are there any potential pitfalls or issues to be aware of when using '==' to compare strings in PHP?

When using '==' to compare strings in PHP, potential pitfalls can arise due to type juggling. This can lead to unexpected results, as '==' does not consider the type of the variables being compared. To avoid this issue, it is recommended to use '===' instead, which performs a strict comparison, checking both the values and types of the variables. 

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

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