Realtime Copying

[Loldongs]

Hey guys,

 

In some webapplications when you are installing say a voice/gameserver it has a realtime/live percentage bar how would i go about making one of these

 

<?php

    shell_exec("cp -Rf skel/css/* /home/dean/port/*");

?>

 

How can i get the percentage that the current copy has done are there any premade classes or library's for this

 

Thanks

Those are pretty tough.  I'm thinking flash is usually the way that is usually achieved, however it may be possible using AJAX and PHP.

I have got it working some what

 

<style type="text/css">

body {
	font-family: Arial;
}

#percentbox {
	width: 300px;
	height: 20px;
	border: 1px solid #936;
}

#progress {
	text-align: center;
	font-family: Arial;
	background: #0F6;
	width: 100%;
	height: 100%;
}

</style>

<script type="text/javascript">

var total = 26906;

function updatePerc(p,up) {

	document.getElementById('files').innerHTML = up+' / '+total;

	document.getElementById('progress').style.width = p+'%';
	document.getElementById('progress').innerHTML = p+'%';
}

</script>


<div id="percentbox">

<div id="progress">
    	0%
    </div>
    <span id="files">0 / 26906</span> files copied

</div>

<?php

if(!($ssh = ssh2_connect('127.0.0.1', 22))){
	die("Connection Error");
}

if(!ssh2_auth_password($ssh, 'root', '***')) {
	die("Username and Password wrong");
}    

$stream = ssh2_exec($ssh, 'cp -Rfv /home/vgame/skel/css /home/vgame/skel/test');

stream_set_blocking( $stream, true );

$data = "";
$nf = 26906;

$i = 0;

$q = false;

    while( $buf = fread($stream,4096) ){
	$lines = explode("\n",$buf);
	$i = $i + count($lines);

	# need this so it flushes
	echo '<p style="display: none;">'.$buf.'</p>';

	$pe = round($i/26906*100,2);
	echo '<script type="text/javascript">updatePerc("'. $pe .'",'. $i .');</script>';

	flush();
}
            
fclose($stream);
?>

 

Just incase someone wants it
