A small question

I was trying something out, and ran into something that seemed odd... I wanted to know what would happen if I: <? $a = array(1,2,3,4,5,6,7,8); $foo = &$a[3]; $next = $foo++; echo $next . "\n"; ?> Hoping that maybe $a[4] would get into $next... Here's what I got: 4 -: Freeing 0x001A50E8 (39 bytes), allocated in zend_hash.c on line 175<br> -: Freeing 0x001A4E48 (4 bytes), allocated in zend_hash.c on line 391<br> -: Freeing 0x001A4DF0 (35 bytes), allocated in zend_hash.c on line 380<br> I'm just not sure if that is the expected result or not...ie, I gather that it doesn't do what I was looking at, but why did I get these errors? Still don't know a _WHOLE_ lot about "C", but is that a memory leak, or just something I caused by trying to increment $foo? --Joey Smith
