title: track php copy() with a progress bar
body: <p>I may have skipped it elsewhere on SO, but if there is a way to track it graphically? When I have a <code>≈300MB</code> media file copied on a local server <code>(note, not remotely)</code>, the entire browser tab is busy, showing the rotating favicon only, till the copying is done. Then only does the page show any info intended for display <code>(file size, destination space available, etc.)</code> before the operation. Any hints will be much appreciated.</p>
