Description: ------------ Hi, Thanks for the package. It's very easy to use and just what I wanted. It throws a warning when attempting to read a file that doesn't exist. It is marked with an @ to tell php you don't care (so in a sense it's a php anomoly). Change Line 271 Lite.php if (@filemtime($this->_file) > $this->_refreshTime) { To: if (file_exists($this->_file) && @filemtime($this->_file) > $this->_refreshTime) { Unfortunately, I have to have warnings creating big ugly error messages. Cheers, Dave. Reproduce code: --------------- $GlobalCache->save("null",$xml_file_name,"null"); if ($data=$GlobalCache->get($xml_file_name, "tree")) { //Goodo $tree=unserialise($data); } else { $tree = new XML_Tree($xml_file_name); $tree->getTreeFromFile(); $tree->get(); $GlobalCache->save(serialise($tree),$xml_file_name, "tree"); } Expected result: ---------------- $tree with no warning Actual result: -------------- $tree with warning

sorry for the delay but I was away from my computer. I will test your patch soon. But, what about perfs ? Still the same ?
 [2004-07-12 23:54 UTC] djpenton at cs dot mu dot oz dot au
I suspect performance will be close to identical. The worst case will cause it to take an extra 1/500 of a second. There is a note on the php page: flobee at gmx dot net 23-Jun-2004 03:05 yust a little note: some people told me that they dont use this function because of taking too much performance/time: well, they are right in some ways: if you expect a file this function runs perferct. if it don´t find a file it takes really long: benchmark in a for() statment 500 circles using file_exists() to be TRUE : 0.00378203392029 using file_exists() to be FALSE: 0.951257944107
