Sorry for the long post but this problem have plagued us for a few
months and we suspect that this is a OS-specific issue with
FreeBSD/PHP, AFAICS it has not been reported from the Linux camp. I'm
posting here in the hope that someone on this list might have a clue.
In brief, intermittently, the first character in a file name is lost
using the PHP basename function. Below is an excerpt from a Horde
webmail server's log that shows the error.
More reading can be found on the Horde list here:

and here
http://marc.info/?l=hordem=124683029904466w=2
- Problem is present on both FreeBSD 6.4 and 7-STABLE
- We see it on two boxes so it's not limited to a single server
- It has occurred on all PHP versions since this year, approx from the
time of PHP 5.2.8 or 9
- It is intermittent - no real pattern
- It does not matter if we use the Horde cache or not, if we use a cache
via PHP or not, have tried a *lot* of configurations to no avail.
A more detailed log:
Obviously, we are looking for memcache.php but $basename sometimes
returns emcache.php.
