> Btw, is "Zend Accelerator" = "Zend Compiler"? One last try: We are talking about two different things. One is the ability to extend the functionality of php. You could for instance want to have a clustalw function that performs sequence allignment. You could simply take the clustalw source code, add some stuff to the source code such that variables will be passed right between php and your code,compile php together with your code, and voila, you now have your function clustalw_allign($sequences, $parameters), which behaves exactly like any other php function. Instructions how to do this are at: http://www.php.net/manual/en/zend.php. The same trick can also be used when you have code that executes slowly in php. If you can compile php, you already have everything you need to do this. The other subject is acceleration of php. The Zend accelerator (or whatever they call it) stores a compiled version of your php script in memory or on disk. This is worthwhile mainly for heavy duty servers (quite a few cpu cycles will be avoided). I have the feeling you are mainly interested in option One.

Ehmm., shouldn't we write the php scripts that write a seqobject to an SQL database (with the structure I am getting into the adodb script right now)? Best, Nico
