Displaying part of HTML before and after system() command

[Aaron Whiffin]

Consider my (simplified) code below:

With my old ISP it used to display "Archiving database images ..." then
paused for a while (30 secs to a few minutes) then displayed complete".

With my new ISP it pauses for ages but doesn't go anywhere

Replacing the system() line with a sleep(5) shows me that it is waiting
until the whole process is complete before outputting ... but for some
reason I think this is going wrong as IE just keeps trying to open page ...
but never does.

How can I get it back to how it was?

Many thanks




set_time_limit(0); // As tar/gzip takes a while
echo "<P>Archiving database images ... ";
system ("tar cvf - $imagedir"."/*.* | gzip -r9 >
$backupfilename".".tar.gz");
echo "complete\n";

print "\n";
flush();

A better solution would be to dissociate the backup from the httpd process:

system ("at now tar -cvzf {$backupfilename}.tar.gz {$imagedir}/*.* | mail -s
backedup arron@somewhere");

File a few hundred Mb - too big to email

Any other tidy ways of doin this?

Cheers for your help

Can I make system verbose and output it's data to PHP (and hence the screen)
as it is processed?

(I'm new to all this)

Cheers
