+ Debugging Tools For Horde 4 or later

++ Horde::debug() [http://lists.horde.org/archives/dev/Week-of-Mon-20110321/025987.html]

To easily debug the value of a variable in Horde PHP code, Horde::debug() can be used.  Usage:

<code type="php">

{{$variable}} is the variable you wish to debug.  The contents of this variable will be dumped into a file named {{horde_debug.txt}} in your temporary directory (generally set in {{horde/config/conf.php}} in the {{$conf['tmpdir']}} variable).  ##red|$variable MUST NOT be debug_backtrace().##

If you want to manually specify the location of the debug file, you can use the optional second parameter to Horde::debug():

<code type="php">
Horde::debug($variable, $filename);

{{$filename}} should be the full path to the filename.  If using {{$filename}}, make sure the directory/file is writable by the user the PHP process runs as.

++ IMP: IMAP/POP3 Debugging

To enable debugging, see instructions contained in imp/config/backends.php (the 'debug' config parameter).
