Are there specific operators in PHP that can be used to connect multiple if statements for validation purposes?

To connect multiple if statements for validation purposes in PHP, you can use logical operators such as && (AND) and || (OR). These operators allow you to combine multiple conditions within a single if statement to perform more complex validation checks.

// Example of connecting multiple if statements for validation using logical operators
if ($username != '' && $password != '') {
    // Perform validation checks here
    if (strlen($password) >= 8 && preg_match('/[A-Z]/', $password)) {
        // Validation successful
        echo "Validation successful!";
    } else {
        // Validation failed
        echo "Password must be at least 8 characters long and contain at least one uppercase letter.";
    }
} else {
    // Validation failed
    echo "Username and password are required.";
}
