Php5 - Clear CLI Output?

Dec 1, 2010

I'm trying to get a "live" progress indicator working on my php CLI app. Rather than outputting as


I would rather it cleared and just showed the latest result. system("command C CLS") doesnt work. Nor does ob_flush(), flush() or anything else that I've found.I'm running windows 7 64 bit ultimate, I noticed the command line outputs in real time, which was unexpected. Everyone warned me that out wouldn't..

How To Get Clear Print() Output

I have some code which displays a page as a .jpg according to user input and also displays html links to a previous page, next page, previous chapter, next chapter as so:

$out = "<img src="/images/{$pic}.jpg" alt="Page {$page}" />";
if ($prevChapter > 0) $out .= "<a href="/mybook.php?chapter={$prevChapter}">Prev Chapter</a>";

The trouble is that the links are all squashed up together, even one on top of another, so you can't see the complete working (i.e. 'next page') and don't know what link you'll get when you click on them.

Clear Output To Change Headers?

Is there any way to have html output and then clear the output to allow for headers to be changed? This is still while the php file is executing. The reason I ask is that I am trying to output a progress bar of an excel file being created. So while the file is being created by php, I want to output to the browser a progress bar and then once it is complete, I need to set headers so that it downloads it as an excel file.

Is this possible or does anyone else have any ideas? Should I maybe save the file on the web server temporarily and then redirect to the file afterwards?

Key() Behavioral Differences PHP5.1.6 To PHP5.2.5

This little script works fine (iterating through MD array) in PHP5.2.5 on development server, but when I publish to production server (PHP5.1.6) it doesn't work (just loops through first sub -- over and over...). The problem appears to hinge on "$new_state= key($cities);" but I can't figure out why, and am stumped as to an alternative.

PHP Code:
$state="AL";//start value
$city="auburn";//start value
