How to avoid php variable moving before html

[Bala Kumaran]

Hello,
The following script is the "times ago" function

<?php
function time_stamp($session_time) 
{ 
$time_difference = time() - $session_time ; 

$seconds = $time_difference ; 
$minutes = round($time_difference / 60 );
$hours = round($time_difference / 3600 ); 
$days = round($time_difference / 86400 ); 
$weeks = round($time_difference / 604800 ); 
$months = round($time_difference / 2419200 ); 
$years = round($time_difference / 29030400 ); 
// Seconds
if($seconds <= 60)
{
echo "$seconds seconds ago"; 
}
//Minutes
else if($minutes <=60)
{

   if($minutes==1)
  {
   echo "one minute ago"; 
   }
   else
   {
    echo "$minutes minutes ago"; 
   }

}
//Hours
else if($hours <=24)
{

   if($hours==1)
  {
   echo "one hour ago";
  }
  else
  {
   echo "$hours hours ago";
  }

}
//Days
else if($days <= 7)
{

  if($days==1)
  {
   echo "one day ago";
  }
  else
  {
   echo "$days days ago";
   }

}
//Weeks
else if($weeks <= 4)
{

   if($weeks==1)
  {
   echo "one week ago";
   }
  else
  {
   echo "$weeks weeks ago";
  }

}
//Months
else if($months <=12)
{

   if($months==1)
  {
   echo "one month ago";
   }
  else
  {
   echo "$months months ago";
   }

}
//Years
else
{

   if($years==1)
   {
    echo "one year ago";
   }
   else
  {
    echo "$years years ago";
   }

}

} 


$session_time = "2012-11-22 22:54:50";
$times_ago = time_stamp(strtotime($session_time));
//$session_time=time();
echo "<h1>You got a friend request from kathir ".$times_ago."</h1><br />";
?>

The script is working properly. but, The php variable is not showing between the html tags. It displays only before the tags.

From the above code I am getting the output as

6 minutes ago You got a friend request from kathir.


I want to get the output like as

You got a friend request from kathir 6 minutes ago.

How should I want to modify the script?

It displays only before the tags.

because you print it there.

check this simple test: var_dump(time_s tamp(strtotime( $session_time)) );

Thx for ur reply. The same problem accuring again and it displays a new "null" value after that. :(

[Dormilich]

what does that tell you?

[Bala Kumaran]

I am getting the output look like this

6 minutes ago null You got a friend request from kathir.

[Dormilich]

your function as it is posted prints the output when you call it. it doesn’t save that in any return value which you didn’t define anyways.

[Bala Kumaran]

Okay. I understood. If I want to display a times ago function between tags like that. How sholud I want to create the code? Could you help me?

[Dormilich]

either place the function where you want the result printed or make the function return the values instead of printing them.
