How can the comparison of $existCount with a specific number impact the ability to authenticate multiple administrators in a PHP application?

Comparing $existCount with a specific number can impact the ability to authenticate multiple administrators in a PHP application because it may restrict the number of administrators allowed to log in based on a hardcoded value. To authenticate multiple administrators, it is better to check if $existCount is greater than 0 rather than comparing it to a specific number. This way, any administrator with valid credentials can log in, regardless of the number of existing administrators. 

// Check if $existCount is greater than 0 to authenticate multiple administrators
if ($existCount > 0) {
    // Authentication logic for multiple administrators
    // Include code to log in the user
} else {
    // Handle authentication failure
    echo "Authentication failed. Please try again.";
}
