Is it possible to define a button in PHP that does not submit or delete data, but instead triggers a specific action?

Yes, it is possible to define a button in PHP that triggers a specific action without submitting or deleting data. This can be achieved by using JavaScript to handle the button click event and perform the desired action. By using JavaScript, we can call PHP functions or make AJAX requests to interact with the server without submitting a form.

<button onclick="myFunction()">Click me</button>

<script>
function myFunction() {
    // Perform your desired action here, such as calling a PHP function or making an AJAX request
}
</script>
