PHP Countdown

[Mutley]

How would I do a countdown in minutes to the next whole hour?

 

Like 23minutes until 1pm.

Simple code:

<?php

// get the current hour (24 hour clock) and increase by 1
$n_hour = date('H')+1;

// Here we work out the hour, in 12 hour clock format
// we also set the am / pm of the hour
if($n_hour > 23)
{
    $n_hour = 12;
    $m = 'am';
}
elseif($n_hour > 11)
{
    $n_hour = date('g', mktime($n_hour));
    $m = 'pm';

}
else
{
    $m = 'am';
}

$c_mins = date('j');

$l_mins = 60 - $c_mins;

$time_left = 'There are ' . $l_mins . 'minutes left until ' . $n_hour . $m;

echo $time_left;

?>

How do I set this for GMT/London times?

[Mutley]

Fixed it using:

putenv("TZ=Europe/London");

 

However the minutes are wrong, it says 50min to 12, when there are only 20.

Add the following line to the top of script:

date_default_timezone_set('Europe/London');

 

<?php

date_default_timezone_set('Europe/London');

// get the current hour (24 hour clock) and increase by 1
$n_hour = date('H')+1;

// Here we work out the hour, in 12 hour clock format
// we also set the am / pm of the hour
if($n_hour > 23)
{
    $n_hour = date('g', mktime($n_hour));
    $m = 'am';
}
elseif($n_hour > 11)
{
    $n_hour = date('g', mktime($n_hour));
    $m = 'pm';

}
else
{
    $m = 'am';
}

// get the current minutes
$c_mins = date('i');

// take the current minutes from 60 (60 minutes in an hour)
$l_mins = 60 - $c_mins;

// Now we set up the message to be shown.
$time_left = 'There are ' . $l_mins . 'minutes left until ' . $n_hour . $m;

// echo the message we setup above
echo $time_left;

?>

 

Fixed it using:

putenv("TZ=Europe/London");

 

However the minutes are wrong, it says 50min to 12, when there are only 20.

I typed j instead i for the the date function when getting the current minutes.

 

That is corrected now.
