On the Linux box compile PHP as CGI (i.e. don't configure it as an apache
mod). Then you can just run your script from the the command-line.

For example:
#!/usr/local/bin/php -q
print "Hello world.\n";

The -q suppresses the html crap that gets spit out. I don't know jack
about Redhat (Debian rocks), you might be able to get an RPM that will
install the php executable for you.

To do the crontab:
crontab -e

15,30,45,0 * * * * name_of_your_script
