How can using multiple form tags affect data submission and processing in PHP scripts?

Using multiple form tags on a single page can cause issues with data submission and processing in PHP scripts because each form tag represents a separate form submission. To solve this issue, you can use hidden input fields within a single form tag to pass additional data to the PHP script. 

<form method="post" action="process.php">
    <input type="text" name="username" placeholder="Username">
    <input type="password" name="password" placeholder="Password">
    <input type="hidden" name="form_type" value="login">
    <button type="submit">Login</button>
</form>

<form method="post" action="process.php">
    <input type="text" name="email" placeholder="Email">
    <input type="text" name="message" placeholder="Message">
    <input type="hidden" name="form_type" value="contact">
    <button type="submit">Submit</button>
</form>
