Undefined variable: argc in BmpCrypt_CmdLine_Example.php

this error is coming :
"Notice: Undefined variable: argc in C:\wamp\www\bmpcrypt-2005-04-21\BmpCrypt_CmdLine_Example.php on line 5

USAGE: To encrypt data and hide it in a bitmap file: php -f BmpCrypt_CmdLine_Example.php -e bitmap_file data_file output_file [key] [level] To decrypt data and recover it from a bitmap file: php -f BmpCrypt_CmdLine_Example.php -d bitmap_file output_file [key]"


Why is it so?whats the matter with the variable argc ?? plz help

In your php.ini, verify if register_argc_argv = 1 (or On)

Actually i am new in all this.so i have this lil bit of doubt that: Do i necessarily have to run the Bmp_Crypt_Example.php through the command line...or if i just run the Decrypt_Webpage_Example.php in the localhost as the web page is enough for encrypting and decrypting data as per the code??

Infact, it depends on what you intend to do ^^
Do you -need- to use it through th e command line, or will you only use it through a navigator ?
If you're never going to need use CLI for crypt/decrypt page, then you don't need to modify your php.ini

yup, i am more interested in using it through the navigator only.
