Как создать этот скрипт в функции PHP?

Question

Вот ссылка, на источник: https://docs.google.com/document/pub?id=1VxiZbysGLVx71ni0biGm2NbhhSCkPZmGWng-ik7IHNQ

<?php 
$user1 = mysql_query("SELECT * FROM `users` WHERE `id`='$user->id'"); 
while($user = mysql_fetch_object($user1)){ 
    $data2 = mysql_query("SELECT *,UNIX_TIMESTAMP(`start`) AS `start`,0 FROM `users` WHERE `id`='$user->id'"); 
    $data1 = mysql_fetch_object($data2); 
    $date = $user->howlong; 
    $timedif1 = $data1->start-3600+$date-time(); 
    if($data1->start + $date > time()){ 
     list($h,$min,$sec)=explode(":",date("H:i:s",$timedif1)); 
     $countdown = $data1->start+$date-time(); 
    } 
} 
?> 

У вас есть <?php echo $countdown ?> время до конца!

Answer 1

Было бы что-то вроде этого:

<?php 

// getCountdown() function 
function getCountdown($userId) 
{ 
$user1 = mysql_query("SELECT * FROM `users` WHERE `id`='$userId'"); 
while($user = mysql_fetch_object($user1)){ 
    $data2 = mysql_query("SELECT *,UNIX_TIMESTAMP(`start`) AS `start`,0 FROM `users` WHERE `id`='$userId'"); 
    $data1 = mysql_fetch_object($data2); 
    $date = $user->howlong; 
    $timedif1 = $data1->start-3600+$date-time(); 
    if($data1->start + $date > time()){ 
     list($h,$min,$sec)=explode(":",date("H:i:s",$timedif1)); 
     $countdown = $data1->start+$date-time(); 
    } 
return $countdown; 
} 

// call function and pass user id parameter 
$countdown = getCountdown($user->id); 
// display function output 
echo $countdown; 

?>

function yourfuction(){ 
    $user1 = mysql_query("SELECT * FROM `users` WHERE `id`='$user->id'"); 
    while($user = mysql_fetch_object($user1)){ 
    $data2 = mysql_query("SELECT *,UNIX_TIMESTAMP(`start`) AS `start`,0 FROM `users` where 
    `id`='$user->id'"); 
    $data1 = mysql_fetch_object($data2); 
    $date = $user->howlong; 
    $timedif1 = $data1->start-3600+$date-time(); 
    if($data1->start + $date > time()){ 
    list($h,$min,$sec)=explode(":",date("H:i:s",$timedif1)); 
    $countdown = $data1->start+$date-time(); 
}
