Question

How can I create a function to use inside a while loop. Like the_title() or the_meta() in WordPress?
A simple sample is enough.

Answer 1

you could use globals. For example, assuming you have a global array, here is something that does that (obviously you need to add more robustness such a error checking. plus how you would use this on wordpress would depend on what you are doing)

$post= array( 0=>array('title'=>'the title', 'content'=>'this is the content'),
              1=>array('title'=>'the second title','content'=>'we all love seconds'),
            );
$array_index=0;
the_title();
the_post();
next_post();
the_title();
the_post();

function the_title() {
   global $post, $array_index;
   echo $posts[$array_index]['title'];
}
function the_post() {
   global $post, $array_index;
   echo $posts[$array_index]['title'];
}
function next_post() {
   global $post, $array_index;
   $array_index++;
}
