What potential issues can arise when using multiple submit buttons in a PHP form?

One potential issue that can arise when using multiple submit buttons in a PHP form is that it may be difficult to distinguish which button was clicked and process the form accordingly. To solve this issue, you can use the name attribute on each submit button and check which button was clicked based on its name in the PHP code. 

// HTML form with multiple submit buttons
<form method="post" action="process_form.php">
    <input type="submit" name="button1" value="Button 1">
    <input type="submit" name="button2" value="Button 2">
</form>

// PHP code to process the form based on the clicked button
if(isset($_POST['button1'])) {
    // Process form for button 1
} elseif(isset($_POST['button2'])) {
    // Process form for button 2
}
