What are the different ways to call PHP scripts using buttons in a web project?

To call PHP scripts using buttons in a web project, you can use JavaScript to make an AJAX request to the PHP script when the button is clicked. This allows for seamless interaction without needing to reload the entire page. Another option is to use a form with a hidden input field that specifies the PHP script to be called upon form submission. This method is useful for passing parameters to the PHP script. ```html <!-- HTML code for a button that calls a PHP script using AJAX --> <button id="myButton">Call PHP Script</button> <script> document.getElementById('myButton').addEventListener('click', function() { var xhr = new XMLHttpRequest(); xhr.open('GET', 'myScript.php', true); xhr.send(); }); </script> ``` ```html <!-- HTML code for a form that calls a PHP script upon submission --> <form action="myScript.php" method="post"> <input type="hidden" name="param1" value="value1"> <button type="submit">Call PHP Script</button> </form> ```
