The code seems to work for me if $pClass->someFunction() actually does something. If it is empty it doesn't appear in the resulting profiler array. For example, here is what I have that works: <?php $pProfiler->start(); function execute() { $pClass = new SomeClass(); $pClass->someFunction(); } execute(); // TICK IS CALLED FROM EXECUTING THIS $pProfiler->end(); class someClass { public function someFunction() { echo "HELLO!"; } } ?> This shows: HELLO!array(4) { ["include"]=> float(2404831569.3143) ["Profiler::start"]=> float(1202415785.3143) ["execute"]=> float(1202415784.6574) ["someClass::someFunction"]=> float(1202415784.6593) } But with an empty someFunction() I get: array(3) { ["include"]=> float(2404831928.8424) ["Profiler::start"]=> float(1202415964.8424) ["execute"]=> float(1202415964.4215) } -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
