determining total of days, hours and seconds between two dates

[bcamp1973]

If i have two timestamps, is there a built in function to give me the different between the two as days, hours and seconds?

No, you have to write it yourself.

[Eugene]

$seconds = $timeStamp2 - $timeStamp2;
$minutes = ($seconds / 60);
$hour = (($seconds / 60) / 60);

 

Don't hold me to this though, I just coded it in about 2 seconds.

thanks for the help! i've used one of the functions from the link tippy_102 provided to created the following. however, it's not working. page doesn't even load   My ISP is using 4.1.21-standard...not sure if that has anything to do with it?  It's not liking the last if() statement where the function calls itself... Any suggestions?

 

function age($startDate,$endDate=NULL){

$difference=strtotime($endDate ? $endDate : gmdate('Y-m-d g:i:s'))-strtotime($startDate);
$periods=array('second','minute','hour','day','week','month','year');
$lengths=array(1,60,3600,86400,604800,2630880,31570560);

for($val=sizeof($lengths)-1; $val>=0 && ($number=$difference/$lengths[$val])<=1; $val--);

if($val<0) $val=0;

$new_time=strtotime($endDate)-($difference % $lengths[$val]);
$number=floor($number);

if($number!=1) $periods[$val].='s';

$text=sprintf('%d %s ',$number,$periods[$val]); 

if(($val>=1) && ((strtotime($endDate)-$new_time)>0)){
	$text.=age($new_time);
}

return $text;
}

[code]actually, found a shorter solution...

function age($startDate,$endDate=NULL){

 

$text='';

 

$seconds=strtotime($endDate ? $endDate : gmdate('Y-m-d g:i:s'))-strtotime($startDate);

 

$periods=array('year','month','week','day','hour','minute','second');

$lengths=array(31570560,2630880,604800,86400,3600,60,1);

 

for($x=0; $x<count($periods); $x++){

if(($temp=$seconds/$lengths[$x])>=1){

$text.=floor($temp).' '.$periods[$x].($temp>=2 ? 's': '').' ';

$seconds=$seconds % $lengths[$x];

}

}

 

return $text.'old';

}[/code]
