Phoenix/Accessing Downloads Data

You can access the Downloads database from within your PHP scripts by using the Database API. For data integrity reasons, this access is read-only. Please note that before using this code, you must register the URL of your PHP page with the eclipse.org webmaster, or it will not work!

	# Sample PHP code to issue a Downloads query.
	#
	
	# :::::PLEASE NOTE:::::
	# There are usually in excess of 200 million records, and queries can take up to a few minutes to execute
	# Don't use these queries in "publicly accessible" web pages!!!
	# Queries that run for more than 5 minutes are killed by the SQL server.
	
 
	# simplisticly silly way of preventing the page from being accessed by just anybody.
	# Linking to page.php?password=abc123 obviously defeats the whole purpose of this.
	$_PASSWORD = $_GET['password'];
	if($_PASSWORD == "abc123") {
