opendir or header()

Anon

having a bit of trouble, and new to this. can't find exact help in the archive or manual so..

on the first line of my php page, i want to check to see if a directory exists -- if so, do nothing

if not, send the header to redirect to an error page

the problem, is that using

if($handle == opendir($myDir)) or header("Location:http://this.com/error.html");

if($handle == opendir($myDir)){
	// do nothing
} else {
	header("Location:this.com/error.html");
}

will not work, because the failed opendir creates an error message, and php can't send the header after an error message is written to the user, so i get another error message too

ugh.

any help would be appreciated

use the "@" character in front of functions to supress error messages.

if($handle == @opendir($myDir)) or header("Location:http://this.com/error.html");

Anytime you have a question regarding a php function php.net has a good online reference.

interesting too -- php.net/manual consistantly crashes my machine (g4/os9.1/ns4)

thank you very much for replies. you saved my day!

The examples on php.net had the same solution and the one posted here?

Optionally you could always use output buffering. It can set either set in the php.ini or called at runtime:

<?php

ob_start();

// ....... your php code here

ob_end_flush();
?>

If your version of PHP is compiled with zlib suport and is 4.0.4 or higher, you can also try this:

<?php

ob_start("ob_gzhandler");

// ... rest of your script

This method will check if the requesting browser supports either gzip or deflate compression. If the browser does (I know that netscape/ie 4.0+ does) the output will be sent using the best available compression type. Hope this helps!!
