Catch all web script

It can sometimes be useful to have a script that captures all the HTTP requests and that logs these requests to a file. The PHP script below works for me. I use this script in combination with the htaccess file to catch all web page requests and redirect them to one file.

<?php
$logfile = "/tmp/webserver.log";
$fh = fopen($logfile, 'a');
fwrite($fh, "\n=== " . date("Y-m-d H:i") . " ====== " . $_SERVER["REQUEST_URI"] . " ===========");
printarray($fh, $_SERVER, "_SERVER");
printarray($fh, $_ENV, "_ENV");
printarray($fh, $_REQUEST, "_REQUEST");
fwrite($fh, "\n");
fclose($fh);

function printarray($fh, $arr, $arrlabel) {
  fwrite($fh, "\n");
  foreach($arr as $key => $value) {
    fwrite($fh, "\n ".$arrlabel."[\"".$key."\"] = ".$value);
  }
}
?>

The .htaccess file :

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^.*$ index.php [NC,L]

The apache config for the virtual host is straightforward.

<VirtualHost *:80>
	DocumentRoot /var/www/
	DirectoryIndex index.php
	<Directory /var/www/> 
		Order allow,deny
		allow from all
	</Directory>
</VirtualHost>
