[Require Usage For Constant]

Thanks a lot for your answer..

Maybe l am not fully understand the language, pls correct if l am wrong

 

 

but my question come up is :

 

<?php

require('../inc.config.php') --> Constant 'MYSQL' defined in this file // e.g. define('MYSQL', 'connection string here');

 

 

// now can use MYSQL anywhere in script

echo MYSQL; //output MYSQL connection string or use MYSQL for connection

?>

my question is if l had already include '../inc.config.php', l already can use 'MYSQL' constant for my connection string anywhere in my script,

why should l write require(MYSQL) again ?

 

Thanks

[Require Usage For Constant]

Hello,

 

l have recently got Effortless E-Commerce this book,

however, when l read 'Selling virtual products' chapter, l come up with a question:

 

the code:

 

<?php

require('../inc.config.php') --> Constant 'MYSQL' defined in this file

 

require(MYSQL); --> require constant

 

...

...

...

?>

 

with this code, since the constant have been defined in inc.config.php, the MYSQL constant should have a global scope to be used and it could be access anywhere using 'MYSQL'.

 

Why bother require(MYSQL) again in this script ?

 

 

i am not quite understanding the usage of this ==

 

hope anyone could provide expert view.

 

Thanks...
