In Perl, I can do this to get the server environmental variables:

foreach $key (sort(keys %ENV)) {
print MAIL "$key = $ENV{$key}\n";
}

Is there a way to do this same thing, in PHP?

Server enviroment variables....not sure exactly which one's you want, but one way is through phpinfo(), or if you want specific, do this

<? 
echo "<pre>";
print_r($_SERVER);
echo "</pre>";
?>

this will tell you alot about your server:

<?php
echo "<html>\n
<head>\n
<title>Envrionment Variables</title>\n
</head>\n
<body>\n
<h1>Envrionment vars:</h1>\n
<table border=\"1\" bgcolor=\"lightblue\">\n";
foreach($_ENV as $key=>$value){
	echo "<tr><td>".$key.": </td><td>".$value."</td></tr>\n";
}
echo "</table>\n
<hr />\n";
echo '<h1>Request vars:</h1>'."\n".'
<table border="1" bgcolor="lightyellow" width="100%">'."\n";
foreach($_REQUEST as $key=>$value){
	echo "<tr><td>".$key.": </td><td>".$value."</td></tr>\n";
}
echo "</table>\n
<hr />\n";
echo '<h1>Server vars:</h1>'."\n".'
<table border="1" bgcolor="cyan">'."\n";
foreach($_SERVER as $key=>$value){
	echo "<tr><td>".$key.": </td><td>".$value."</td></tr>\n";
}
echo "</table>\n
</body>\n
</html>";
phpinfo();
?>

the envrionment variables are stored in the $_ENV superglobal.

Ah thanks!!!

this is what I was looking for:

foreach($_SERVER as $key=>$value){
echo $key.": " . $value."<BR>\n";
}
