I'm using wordpress, and I have some variables that I need to use on some other pages, these variables are on different files that are included on the index (<?php include('somefile.php');?>).
My question is the variables from somefile.php can be echoed directly on index.php ? If yes can you tell me how ?
Thanks in advance
Yes
<?php echo $someVariable ?>
Wordpress is notorious for loading everything and the kitchen sink into the global space. What this means for you is that generally any variable defined in an included file that is not within a function or method can be used just about anywhere else.
The thing you have to be careful of is conflicts or overrides. For instance, I wouldn't declare any variables named $wp or $wpdb.
Easiest thing to do is here come up with a pseudo-namespacing system. For example, prefixing your classes, global variables, etc with your name / company name is a good approach, eg
// somefile.php
$daniel_somevariable = 'foo';
