strange behaviour of mysql_pconnect()

Hi list, I do a small test on mysql_connect() and mysql_pconnect(), and discover a strange behaviour. <? $cid1 = mysql_pconnect($host,$user,$pass) or die("cant connect1"); $cid2 = mysql_pconnect($host,$user,$pass) or die("cant connect2"); echo $cid1, $cid2; ?> the output if using mysql_connect(): Resource id #1 Resource id #1 (both resource id are the same, as expected) the output if using mysql_pconnect(): Resource id #1 Resource id #2 (both resource id are different) at first I though pconnect() will create 2 different connection because the printed resource id is different. But after doing some test (by looking at the mysql processlist) i can conclude that those two link_identifier are actually the same (only one link, but with two different id) the question is, why pconnect() print different resource id, whereas connect() print the same one? -- Jimmy ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ You can't quicken the growing of a plant by pulling the leaves
