如何在特定服务器时间在php页面上使用javascript执行iframe？ [关闭]

So,

I do not know exact how to do this but here is the thing -

I have the following with me -

1 PHP page let's say wordpress

1 iframe code lets say the following -

Now, my concern is this -

How do i execute this IFRAME on this PHP Page at specific time intervals counted by server time.

So, i need this IFRAME to work from 12AM to 12PM server time, how do i do this.

Sorry i am not a big coder or something.

Just to build on Marco Mura's answer, here is the code example:

Declaring full variables:

$time_now = date('H:i'); //24 hour date format with leading zeros
$range_start = date('H:i', strtotime('00:00')); //Midnight
$range_end = date('H:i', strtotime('12:00')); //Midday

if(($time_now >= $range_start) && ($time_end <= $range_end)){
    //Go to iframe.
}else{
    //Do nothing
}

Simplified:

$time_now = date('H:i'); //24 hour date format with leading zeros

if(($time_now >= date('H:i', strtotime('00:00'))) && ($time_end <= date('H:i', strtotime('12:00'))){
    //Go to iframe.
}else{
    //Do nothing
}

Cool
