This script is incomplete. The switch case for months references undefined variables required for the calculation.

Indeed there is something missing on “date(“j”, $dateto), date(“Y”, $datefrom)) 7)”.
Does not work.

function get_time_difference( $start, $end )
{

$uts['start'] =$start;
$uts['end'] =$end;

if( $uts['start']!=-1 && $uts['end']!=-1 )
{
if( $uts['end'] >= $uts['start'] )
{
$diff = $uts['end'] – $uts['start'];
if( $days=intval((floor($diff/86400))) )
$diff = $diff % 86400;
if( $hours=intval((floor($diff/3600))) )
$diff = $diff % 3600;
if( $minutes=intval((floor($diff/60))) )
$diff = $diff % 60;
$diff = intval( $diff );
return( array(‘days’=>$days, ‘hours’=>$hours, ‘minutes’=>$minutes, ‘seconds’=>$diff) );
}
else
{
return -2;
//trigger_error( “Ending date/time is earlier than the start date/time”, E_USER_WARNING );
}
}
else
{
return -3;
//trigger_error( “Invalid date/time data detected”, E_USER_WARNING );
}
return( false );
}

Did not work on this line:

date(“j”, $dateto), date(“Y”, $datefrom)) 7)

is this

date(“j”, $dateto), date(“Y”, $datefrom))==7)

date(“j”, $dateto), date(“Y”, $datefrom)) < 7)

thanks

@Rajeev: Thanks for the heads up. Actually, Hasin Hyder wrote this post, he was merely following on from a similar post I made on “relative time” (see http://www.developertutorials.com/blog/php/give-your-visitors-relative-y-php-69/). He will probably link the original post now that you have pointed it out, but I’ll leave it up to him; the comments on that post are quite useful as well.
