ImpossibleIdenticalComparison

An identical comparison (===) between values of incompatible types that can never be true. This indicates dead code or a logic error.

Example

<?php
function checkType($value): bool {
    if ($value === 'string' && $value === 123) {
        // This can never be true - a value cannot be both string and int
        return true;
    }
    return false;
}

How to fix

Review the comparison logic and remove impossible conditions:

<?php
function checkType($value): bool {
    // Check for string OR int instead
    if ($value === 'string' || $value === 123) {
        return true;
    }
    return false;
}
