Clear Screen?

[ajicles]

I have kind of a dumb question, but is there some way to clear what I have just echo after a certain amount of time? I have my script and I tried to delay it by using sleep and it just delay the time it took to load the webpage lol.

 

Thanks

	$fp = fsockopen("$server", $port, $errno, $errstr, 30);
	fputs($fp, "GET /admin.cgi?pass=".$password."&mode=viewxml HTTP/1.0\r\nUser-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0)\r\n\r\n");
	while (!feof($fp)) {
		$content = fgets($fp);
	}
	$pattern = "/<SONGTITLE>(.*?)<\/SONGTITLE>/si";
	preg_match($pattern, $content, $matches);
	echo $matches[1];

<script type="text/javascript">
function hide(){
document.getElementById('hideme').style.display = 'none';
}
function sethide(){
setTimeout("hide()",5000);
}
</script>

<div onload=\"sethide()\" id=hideme>YOUR STUFF TO HIDE</div>

 

will hide it within 5 seconds

 

Should work ....

With PHP only method you'd have to do a refresh on the page... passing some flag variable. Otherwise display it with in the first place with javascript maybe as suggested by runthis

I don't really want to hide it but, I was googling around and there is a cool guy from youtube who said:

 

The easiest way to "clear screen" is pretty ghetto but it works. Just echo new lines where you want to clear the screen =P.

while(true){
for ($i=0;$i<30;$i++){
echo "rn";
}
}

 

But it doesn't really work for me.

 

I just want to echo the new data over the old. It's only one line but it should work.

 

	$fp = fsockopen("$server", $port, $errno, $errstr, 30);
	fputs($fp, "GET /admin.cgi?pass=".$password."&mode=viewxml HTTP/1.0\r\nUser-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0)\r\n\r\n");
	while (!feof($fp)) {
		$content = fgets($fp);
	}
	$pattern = "/<SONGTITLE>(.*?)<\/SONGTITLE>/si";
	preg_match($pattern, $content, $matches);
	echo $matches[1];

 

I just need to learn how to make the script pause before starting up again. The only thing with sleep command is it just holds up the webpage from loading during the seconds it is waiting  :-\

Take a look at this site. It should give you a very good idea as to accomplish what you are trying to do.

When a PHP script is run it doesn't send the page to the browser until it is done processing. You can't send a page tothe browser then have PHP interact with that page by itself. THe user needs to initiate some action to ask the server for new information such as the user clicking a link or JavaScript running in the client's browser that will initiate the request.

 

So, you need a client-side solution. But, in this case, even JavaScript is not needed since there is a simple HTML solution. The meta refresh tag.

<meta http-equiv="refresh" content="10;url=http://www.domain.com/pagetoredirect.php">

 

Put a line like that in the HEAD section of the HTML page and after 10 seconds it will refresh the page by opening the URL http://www.domain.com/pagetoredirect.php

I just don't want to have to use a iframe or refresh the page. I'm keep looking for an answer.

I found a script but it doesn't do much except display my part of my code lol.

 

Returns:
