CGI and PHP

Anon

I found this in a cgi script and it would really come in handy for my website. Thing is, i hate cgi, and was wondering if anyone recognises anything or if anyone can "translate" it into php? here it is - hope it pastes ok :-)

Create directory

mkdir ("$config{'root_dir'}/$in{'username'}", 0755) || &error_html("Could not create user directory: $!");

	# Create default html
	open (INDEX,">$config{'root_dir'}/$in{'username'}/index.html") || &error_html("Could not create default user index.html: $!");
	print INDEX qq~

<head>
<title>$in{'username'}\'s homepage</title>
</head>
<body bgcolor="#FFFFFF">

<big><big>$in{'username'}\'s homepage</big></big>
Sorry, my homepage is under construction. 
Please come back at a later time.

</body>

~;
close (INDEX);
}

$index = fopen ("$config{'root_dir'}/$in{'username'}/index.html", 'r') or error_html("Could not create default user index.html: $config{'root_dir'}/$in{'username'}/index.html");

ob_start();

ob_end_clean();
fwrite($fp, $str);
fclose ($index);
