You can also use PHP for shell scripting - just add #!/path/to/php -q as
the first line of your script.
Note: You will still need to enclose all PHP scripting in ?php ... ?
tags.
Here's an example:
file: phpinfo.phpshell
? phpinfo() ?
The preceding information was returned by PHP info.
Just use \n. Both OS's understand this to be a linefeed and will behave
accordingly.
With the exception of a class that performs POP3 queries, I've never had
to use \r\n in my code.

Yes, you can return false.
As for "true booleans", PHP doesn't really have a boolean type - it does
have a sense of "true" and "not true" though. You can return false (a

Yea, it's true. There was a post a couple of weeks ago from Rasmus

This is an example of using a "bareword" - PHP doesn't recognize _dog_ as
