Odd looking function in error

[nathanhornby]

PHP Warning: file_put_contents(../cache/feed.xml) [function.file-put-contents]: failed to open stream: No such file or directory in /Users/Nathan/httpdocs/******/lib/FeedCache.php on line 61

This is what I'm getting after replacing 'ROOT' with the actual path (ROOT isn't defined anywhere).

Odd that the function is within an anchor tag in the error? :s

Sorry about that. I had ROOT defined elsewhere in my app. It was set to:
$_SERVER['DOCUMENT_ROOT']

I replace the instance of ROOT in the script with $_SERVER['DOCUMENT_ROOT'].
