Your variable is 2002-05-11 15:13:02.933.
say
$field = "2002-05-11 15:13:02.933";
explode your variable on space like this-
$var2 = explode(" ",$field);
This will explode the variable at space and then give u an array which has elements seperated by space. u will get an array of size 2.
$var2[0] will give u required part,
other will have time.
