string $function_name: The name of the function calling this method

debug_text (line 176)

Prints debug text if debug is enabled.

return: Always returns true

boolean debug_text (string $text)

string $text: THe text to output

get_cache (line 595)

Uses PEAR's Cache_Lite package to grab cached arrays, objects, variables etc...

using unserialize() so it can handle more then just text string.

mixed get_cache (string $cache_id)

string $cache_id: The id of the cached object

put_cache (line 614)
