Of course you could do the echo serialize form but that isn't going to tell you how much memory it uses internally within the engine itself. Granted this might not either, but it is at least a little closer. var_dump(memory_get_usage()); $array = array( 1 => 'one', 2 => 'two', 3 => 'three' ); var_dump(memory_get_usage()); Output: int(53464) int(53928) Also Xdebug trace: Version: 2.0.0 TRACE START [2008-01-08 14:13:17] 1 0 0 0.004355 51968 {main} 1 /Users/eric/Sites/blah.php 0 1 0 1 0.004833 52328 0.0052 23184 TRACE END [2008-01-08 14:13:17] -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
