What potential issues can arise when using the JavaScript confirm function for data deletion in PHP applications?

Using the JavaScript confirm function for data deletion in PHP applications can lead to potential issues such as users accidentally deleting data without confirmation or bypassing the confirmation dialog altogether. To solve this issue, you can implement server-side validation to ensure that the deletion request is legitimate before executing it. 

<?php
if(isset($_POST['delete'])){
    // Perform server-side validation before deleting data
    // For example, check if the user is authorized to delete the data
    
    // If validation passes, proceed with the deletion process
    // Delete data from the database
}
?>

<form method="post">
    <button type="submit" name="delete" onclick="return confirm('Are you sure you want to delete this data?')">Delete Data</button>
</form>
