First of all, don't do that. :-)
Instead, set up a "job" system of what should be copied/tarred, and
then notify the user via email.
Don't make the user sit there waiting for the computer!
If you absolutely HAVE to do this due to a pointy-haired boss...
<?php
$path = "/full/path/to/1000s/of/files";
$dir = opendir($path) or die("Change that path");
$tmp = tmpname(); //or whatever...
while (($file = readdir($dir)) !== false){
echo "$file<br />\n";
copy("$path/$file", "/tmp/$tmp/$path");
}
exec("tar -cf /tmp/$tmp.tar /tmp/$tmp/", $output, $error);
echo implode("<br />\n", $output);
if ($error){
//handle error here!
die("OS Error: $error");
}
?>
shameless plug:
//handle error here could perhaps use this:
http://l-i-e.com/perror.
