How to refresh a page with PHP script using Javascript
How to update echo using javascript? I have something like this:
<?php
$today = time();
$todayStr = date('D');
$summerS = mktime(0,0,0,2,0,date('Y'));
$summerE = mktime(0,0,0,12,21,date('Y'));
$close = mktime(17,0,0,date('n'),date('j'),date('Y'));
if ($today >= $summerS && $today <= $summerE)
{
if ($todayStr == "Sat")
{
$open = mktime(8,0,0,date('n'),date('j'),date('Y'));
if ($today >= $open && $today <= $close)
{
$openT = "Otevřeno";
}
else
{
$nextO = date("H:i:s",($open - $today));
$openT = "Zavřeno";
}
}
elseif ($todayStr == "Sun")
{
$open = mktime(8,0,0,date('n'),date('j'),date('Y'));
if ($today >= $open && $today <= $close)
{
$openT = "otevřeno";
}
else
{
$nextO = date("H:i:s",($open - $today));
$openT = "zavřeno";
}
}...
<p>Právě je <?php echo $openT ?></p>
And I don't even know how to update this echo in the <p> to display the time for the second.

You cannot "refresh" the echo with javascript as the echo code is executed on the server and the javascript is executed in the browser.
Your two best options:
- Do all the calculations you do in your PHP client side. Javascript
- Create a web service that returns $ openT and will call that endpoint using AJAX in the browser.
