Hi at all
I call this function when I fill the foot of the body of the email that I'll
send immediately after:
$text.=serial_number();
function serial_number()
{
$file="serial.txt";
for ($try = 0; $try < 5; $try++)
{
$fp = fopen($file, "a+");
if (flock($fp, LOCK_EX)) { // do an exclusive lock
fseek($fp, 0);
$id = fread($fp, 1024);
$id++;
ftruncate($fp, 0);
fwrite($fp, strval($id));
flock($fp, LOCK_UN); // release the lock
break;
}
else
{
sleep(1);
continue;
}
}
fclose($fp);
return $id;
}
The email is sended better and into the last line of the body there is the
new serial number
BUT......... IMMEDIATELY AFTER is sended a second EMPTY email without body
that contain only the serial number (new)
Please where wrong I?
Thank you very much in adbance
Pablo
