What are the potential issues with having multiple independent forms within a single PHP file?

Having multiple independent forms within a single PHP file can lead to confusion and potential conflicts between form submissions. To solve this issue, you can use separate form processing logic based on the form submitted.

if(isset($_POST['form1_submit'])){
    // Process form 1 data
}

if(isset($_POST['form2_submit'])){
    // Process form 2 data
}
