Refresh single page PHP element using button
Question by Michael C
I have a single page quote generator, it works by holding the quotes in a 2D array and generating a random number to pull from the matching value in the array using PHP every time that the page is refreshed, I want to change this and make it so that only the element is changed when you press a button, reducing the http requests to the server.
I have tried various “onClick” methods but they never seem to work, I’m assuming that this is something that I should use Javascript (Or any js libraries) for. The function that I want to run when the button is pressed is this:
<?php
$max = max(array_map('count', $arrCSV));
$num = rand(0,$max);
$quote = $arrCSV[0][$num] . "." ;
echo $quote;
?>
Any help is much, much appreciated.

Like, @Dr.Kameleon, this cannot be done with PHP alone.
Using jQuery, you can reload an element like this
$("#yourdiv").load("the/page/from/where/it/should/be/updated.php");
Attach it to the click event of the button
$("button").click(function() {
$("#yourdiv").load("the/page/from/where/it/should/be/updated.php");
});
