# phpwrap.cgi
#
# This script 'fools' php interpreter so that you can give full URL with parameters
#  in cron environment.
#
#  Example crontab:
#  7 * * * * $HOME/htdocs/protectedsubdir/phpwrap.cgi 'http://yourdomain.com/subdir/whatever.php?abc=1234&ghi=heyhey' >pwlog.txt 2>&1
#
# Note that URL is in single quotes. 
# If the URL contain single quote, somehow, you must escape it with backslash \
#
# This script will let you to invoke a php script that needs these parameters and other
# env variables to work properly.
# You may want to add more env variables as you need.
#
# You can use this script as cgi, too. (For testing, e.t.c.)
#
# Example:
# http://yourdomain.com/protected/phpwrap.cgi?http://yourdomain.com/sub/whatever.php?a=3&b=5
#
# I guess it can be used for reaplacing wasteful url_open local include()
#
# In place of:
#    include("http://localhost.yourdomain.com/sub/abc.php?x=1&y=21&z=9")
# you can use;
#  echo  `$DOCUMENT_ROOT/protected/phpwrap.cgi  -nh 'http://localhost.yourdomain.com/sub/abc.php?x=1&y=21&z=9`' ;
#
# If you need to process the page again in the current php script, use "eval" instead of "echo".
#
# Although it invokes additional shell and additional php, it doesn't invoke additional Apache.
# So, maybe it uses less resources than local url_open include().
