Functions.php File Error

After receiving an error from a functions.php edit, i went to replace the problem functions.php file with the original from the theme (which has worked before) and may have inadvertently placed it in the wp-includes dir. I’ve made sure the original functions.php is in the theme directory and have tried to delete functions.php from the wp-includes dir but no luck.

$dir = dir(TEMPLATEPATH.”/”);

Not quite sure how to execute that. Can you provide how-to?

OK. Modified file per above, replaced existing file on site, re-downloaded but no dump result. Is there something I need to do to execute the command?

Here is what I get.

function get_availableCss(){
$result = array();
$dir = dir(TEMPLATEPATH.”/”); var_dump($dir);exit;
while (false !== ($file = $dir->read())) {
if(ereg(“\.css”, $file, $r)){
$result[] = $file;
}
}
$dir->close();
return $result;
}

Not sure if the dump should appear in functions.php file or on the web page after the modified file is loaded. Here is from the file:
/*
Get Available CSS
*/
function get_availableCss(){
$result = array();
var_dump(TEMPLATEPATH.”/”);exit; $dir = dir(TEMPLATEPATH.”/”);
while (false !== ($file = $dir->read())) {
if(ereg(“\.css”, $file, $r)){
$result[] = $file;
}
}
$dir->close();
return $result;
}

Here is from the site with the modified file loaded.

Warning: dir(TEMPLATEPATH/) [function.dir]: failed to open dir: No such file or directory in /home/content/26/9196326/html/wp-includes/functions.php on line 100

Thanks very much Andrew. I appreciate your efforts.
