define/$var

[PrateekSaxena]

Hi,I am a complete n00b at PHP.Please tell me the difference between.define(NAME, 'prateek');and $name ='prateek'.Also I am not able to include('some.php?q=t');why is that?

For the first one - the former statement defines a constant, which does not change all through script execution, while the latter defines a variable which can be changed.For your second question, you cannot pass querystrings through include() statements, instead just define a variable and read it from the included script

$q = t;include("some.php");

For your second question, you cannot pass querystrings through include() statements

To add to that, $_GET inside an included file refers to the same variables as $_GET outside the file, it's the same array. Using $_GET inside an included files doesn't include any variables in the include statement, only variables in the URL of the page itself.

Think of the include() function as simply copying and pasting the code from the included file into your main script.

Sorry for such a delayed reply.is include like require() in ruby?

Yes, but there is also a require() function in PHP: http://au.php.net/manual/en/function.require.php
