RE: [PHP] flush output error
-Original Message- From: electroteque [mailto:[EMAIL PROTECTED]] Sent: 19 December 2002 07:52 sorry about the false alarm , if you go here u will see a working example http://galleries.dyndns.org:1023/progress.php i had to add both flush functions together to work , obviosuly flsuh is not emptying the buffer within a loop, is this still a bug ? flush(); ob_flush(); Well, if you use PHP's output buffering, you actually have two buffers: the output buffer which can be manipulated and accessed from within your script using the ob_*() functions, and what might be called the connection buffer which exists in the general PHP environment and is not accessible to your script, but can be flushed with the flush() function or by setting implicit_flush to on. When you do ob_flush(), this flushes the output buffer to the connection buffer; flush() flushes the connection buffer, via the HTTP connection, to your browser. (The browser may then buffer it itself, e.g. whilst waiting for a /table tag to show up, but that's another matter!) So, yes, if you have output buffering on you need both ob_flush() and flush() (in that order!) to flush all pending output to the browser. For your application, I would question whether you need output buffering on -- it seems to be causing you problems rather than solving them! Cheers!

hi guys i have a little problem with flushing the buffer output, in this
loop it should be downloading a file and changing the progress of a progress

shell_exec is finished , is this a bug ?
php can't multitask, so it's not a bug
what you can try:
page1: (start process)
put an ignore_user_abort on it
put a header location on it to page2
start the command and let it write to a file where it is
page 2 :
read the file and display a processbar
(with javascript or meta refresh)
when done goto page3
page3:
continue
foreach ($filename as $file){
shell_exec(curl -O .$url.$file);
//shell_exec(wget .$url.$file);
//echo $file;
$bar-progressbar_percentage($i,$filename,'NewWin','Percentage','Downloading
'.$file);
$i++;

Re: [PHP] flush output error
no this has been working before, it stopped working ever since i upgraded to
4.3 , whats there to multitask ? i'm simply executing curl and then
executing the funtion after not at the same time but should both be
executing within the same loop , it was working before especially for image
uploads but now it isnt ??
