What are the potential pitfalls of using OR operators in PHP conditionals when checking multiple variables for empty values?

Using OR operators in PHP conditionals to check multiple variables for empty values can lead to unexpected results because the OR operator will return true as soon as one of the conditions is met. This means that if the first variable is not empty, the subsequent variables will not be checked. To ensure that all variables are checked for empty values, it is better to use nested if statements or the empty() function for each variable individually.

if (empty($var1) || empty($var2) || empty($var3)) {
    // Handle empty variables
}
