 I'm having this weird problem on a customer server, whereby Array gets
 displayed all over the place. I've reuploaded and reuploaded thinking it
 was a mere corrupt file problem, but to no avail.

 The symptom is most clear in the plugins folder, where pretty much every
 file in the plugins folder that are _not_ plugins gets listed, as in:

 {{{
 Array   Array By Array.   Activate
 }}}

 ... with an activate link that points to a completely irrelevant file.

 Other areas where Array shows up include the default post slugs, weird
 additional items to the static page list in the pages widget, and so on.

 If anything, I'm guessing an error is occurring in each and every location
 where the empty() function is used to check if a string or an array is
 empty. Why not use variable === '' and !$variable respectively?

 I'm attaching the phpinfo details, as I'm guessing it has something to do
 with the server configuration.

 Also for reference, if I add this in the get_plugin_data() function to
 inspect:

 {{{
 var_dump($plugin_name, $plugin_name[1], trim($plugin_name[1]));
 }}}

 it returns stuff like:

 {{{
 array(2) {
   [0]=>
   string(20) "Plugin Name: Akismet"
   [1]=>
   string(8) " Akismet"
 }
 string(8) " Akismet"
 string(7) "Akismet"

 array(0) {
 }
 array(0) {
 }
 string(5) "Array"
 }}}

 along the same lines, if I add the following in the post editor:

 {{{
 var_dump($post, $post->post_name);
 }}}

 it returns the following when I browse to Write / Write post:

 {{{
 object(stdClass)(11) {
   ["post_status"]=>
   string(5) "draft"
   ["comment_status"]=>
   string(6) "closed"
   ["ping_status"]=>
   string(4) "open"
   ["post_pingback"]=>
   string(0) ""
   ["post_category"]=>
   string(1) "1"
   ["post_content"]=>
   NULL
   ["post_title"]=>
   string(0) ""
   ["post_excerpt"]=>
   string(0) ""
   ["page_template"]=>
   string(7) "default"
   ["post_parent"]=>
   int(0)
   ["menu_order"]=>
   int(0)
 }
 array(0) {
 }
 }}}

 and that last value will result in Array getting displayed as the post
 slug.

 anyway... I'm having the customer change hosts from lack of any better
 options, but I figured I'd highlight this in case anyone else gets the
 problem.
