Very very useful!
I was building a chat and I wanted my script to detect when the browser was closed, so the user could be deleted from the online_users table.
<?
echo str_repeat(" ",300);
ignore_user_abort(true); //this way, the user can stop the output, but not the script.
while (true) {
echo "test<br>\n";
flush();
sleep(2);
if (connection_status()!=0){
include ('dbconnect.inc');
$sql="delete from online_users where online_user=$user";
$sql_exec=pg_exec($vChatDB, $sql);
die(); //kills the script
}
}
?>
