What am I missing?
The code below should begin by echoing to the screen "PROCESSING. . . . " Then the user should be forced to download "filename". If the user cancels or the download finishes, then a text file and a database table are updated. Then the "find_stat" function should echo to the screen "FAILED" or "COMPLETED". Then the page should be finished.
<?
ob_start(); //OPEN FIRST BUFFER
function print_to_screen() //FUNCTION TO NOTIFY USER THAT PAGE IS PROCESSING
{
ob_start();
echo "PROCESSING. . . . . .";
ob_end_flush();
}
Function download_file() //FORCE DOWNLOAD OF FILE
{
ob_start();
Ignore_User_Abort(True); // finish the script after it starts running
$start_time = time();
$filename = "IPTV_Viewer_Setup.exe";
$ext = substr( $filename,-3 );
if( $filename == "" ) {
echo "<html><body>ERROR: Empty file</body></html>";
exit;
} elseif ( ! file_exists( $filename ) ) {
echo "<html><body>ERROR: File not found</body></html>";
exit;
};
switch( $ext ){

?>
So far the only thing that the code does is force the file download. What about the rest? Why is it not running the other fuctions?
SYSTEM SPECs: redhat ES, MySQL 4.3, APACHE 2.0, PHP 4
Any help would be great....
Thanks,
