Comparing times

[Josh18657]

I've been searching here and the php manual for the entire day trying to figure this out.

What I have is a time in this format, 6:32:47 PM and I want to compare it with the server time. If it is more than 20 minutes behind then I want to display a message.

What I came up with was to break that time into pieces 6 32 47 PM and try to convert it into unix style using mktime. I didn't get any further untill I ran into a problem I can't figure out. For some reason in the my code $mbmtime_hour want's to convert to 12 where marked even though it should be the right hour (it's not noon or midnight). if someone could please show me how to fix this or maybe make the code shorter it would definatly be apreciated.

<?

$data3 = 6:42:47 PM 

$input = "$data3"; 
list($tmp_1a, $tmp_2a, $tmp_3a) = explode(':', $input); 
list($time3a) = explode(':', $tmp_1a); 
list($time3b) = explode(':', $tmp_2a);
list($time3c) = explode(':', $tmp_3a);

$input = "$time3c"; 
list($tmp_1b, $tmp_2b) = explode(' ', $input); 
list($time3d) = explode(' ', $tmp_1b); 
list($time3e) = explode(' ', $tmp_2b);

$mbmtime_hour = $time3a;
$mbmtime_minute = $time3b;
$mbmtime_seconds = $time3d;
$mbmtime_AMPM = $time3e;
$mbmtime_minute2 = ($time3b + 20);



echo date("M d Y, g:i:s",mktime('$mbmtime_hour,$mbmtime_minute,$mbmtime_seconds'))."<br>"; //problem line

$mbmtime_mk = mktime($mbmtime_hour,$mbmtime_minute,$mbmtime_seconds);

echo $mbmtime_mk ;

?>

Why not add the current date to the time? Then you could do something like this:

$local_time = strtotime('2005-12-26 6:32:47 PM');
if ((time() - $local_time) > (20 * 60)) {
    echo 'Local time is more than 20 minutes behind server time.';
}

or:

if (strtotime('-20 minutes') > $local_time) {
    echo 'Local time is more than 20 minutes behind server time.';
}

Thank you for the help. i knew there had to be a much easier way 🙂 Got one more problem though.

What's an easy way to change a date that looks like this, 12/26/2005 to this 2005-12-26 ? also I am pretty sure there is a space before and after the date because it showed when i tried to break up the line with explode.

Thanks again

list($m, $d, $y) = trim(explode('/', $date));
$ndate = $y.'-'.$m.'-'.$d;

I can't figure this one out. The following code out puts this.

12/27/2005

Notice: Array to string conversion in F:\Program Files\Abyss Web Server\htdocs\fold_mon\more_info.php on line 382
a-r-r

<?

$data3 = "12/27/2005";
echo $data3."<br>";
list($x, $m, $d, $y, $x) = trim(explode('/', $data3)); 
$ndate = $y.'-'.$m.'-'.$d; 
echo $ndate;

?>

1.) Why 5 list items when there will only be 3 after the explode? That's where your error comes in...

2.) There are other ways, that was just one. Read the user notes for [man]date[/man] and you'll see some conversion techniques.

EDIT
If you remove the trim() it will work.
