Hello all,

 

As i am beginner in php programming

 

I just want to know that what is the functioning of all these followings,which are generally used in php :-

 

 

(1)    $_SERVER['REMOTE_ADDR'];

 

 

 

(2)    what is : - $uself

 

 

& what it means:-

 

$headersep = (!isset( $uself ) || ($uself == 0)) ? "\r\n" : "\n" ;

 

 

 

(3)    $_SERVER['HTTP_REFERER'];

Hi, the variable $uself could be anything? Depends on what the programmer assigned to it before.

This looks like homework, or an assignment.  What do you think each one means?

 

Check out the link that WolfRage posted and don't just re-post your question because the answer you got wasn't what you wanted!

 

Also, check the manual for info on language variables

$headersep = (!isset( $uself ) || ($uself == 0)) ? "\r\n" : "\n" ;

As for this, have a look here:
