How to add a print button to a web page

To add a print button to a web page using PHP, you can use the following steps:

1. Create a button element in your HTML code with a unique id, such as "print-button".

<button id="print-button">Print</button>

2. Use JavaScript to attach an event listener to the button element that listens for a click event.

document.getElementById("print-button").addEventListener("click", function() {
    window.print();
});

3. Optionally, you can also use JavaScript to add a stylesheet to the page that is specifically for printing, and then use CSS media queries to hide elements on the page that you don't want to print.

<link rel="stylesheet" type="text/css" media="print" href="print.css">

@media print {
    /* styles to hide elements on the page while printing */
}

Finally, you should test the print button in different web browsers and make sure that it works as expected.
