[users] php shell script questions

[bill]

I need to run a php script from cron.
I will be developing it from the console using the cli.
for debugging use, do echo statements echo to the console or do I need 
to explicitly open the console for output ?
when I finish the testing and want to start it from cron, would I use
php {scripname.php}  as the cron command, or is there a shebang that I 
can put at the head of the script and then just cron the scriptname ?
