php programming help needed :-)
 

atm im learning php from this tutorial; http://hotwired.lycos.com/webmonkey/...tw=programming

in the 2nd code listing it checks to see if the variable $id exists using if ($id), when i try and run this it errors sayin id is an undefined variable (it doesn't exist), the only way to fix the error is to define it ( eg $id = 0 ), which would lost the point in the whole if statement!

the if ($id) checks if the id variable has been set (which would of been from the command line eg test.php?id=1 )

anyone know whats wrong with this?

i'd like to point out that PHP is an excellent web scripting language, ive been using it for 2 days now and i love it :D

i'd recommend it to anyone, especially if your used to C/++ syntax (eg perl, java) and also used to ASP

its easy to learn, fast to use, put it with MySQL and its amazing ;D

yes. look at the first line in my sig. Now look at the loction of the random image of my sig. It's a PHP script that does a binary read of a image under the folder name of &catagorey and prints it to the browser.
