Ok, dumb question, and i have tested, but I want to ensure that my tests
were accurate, and behavior is correct.
Ok, i have an integer, that based on what it is, does certain things...
switch ((int)$intval)
{
}
now, if i need to do something on a few of the numbers, then:
case 0:
# do nothing as strings will be (int) as 0
break;
case 1:
# do this
break;
case 12:
# do this
break;
default:
# do everything that is general to this
which this works, as the $intval should never be anything that i am not
expecting as there is another part of the code that decides which int's
to send to this class.
but is there a better way to do this? this could potentially do a lot
more, and be more dynamic, but there is also the possibilty that i need
to have more "custom" commands based on an integer value, and not
something that is "generic".
Is there a way to only do from like cases 2-11, without doing:
case 2:
case 3:
case 4:
.....
case 11:
# do this stuff
break;
am I just overthinking things? i dunno... it's monday... brains still
on weekend mode.

There is actually a very cool way you can use a switch in PHP to do what
you want:
switch(true)
{
case ($intval >= 2 && $intval <= 11):
{
// stuff here for cases 2-11 inclusive
break;
}
}
Although I think in your case a series of if/else if statements would
work, and might possibly be more readable in your code.
Thanks,

Example:
$simple = "select count(*) as count, searchkeywords from searchtable group
by searchkeywords order by count desc";
$stuff = mysql_query($simple);
If(mysql_num_rows($stuff) >= 1)
{
While($toarray = mysql_fetch_assoc($stuff))
{
$doit = mysql_query("INSERT INTO mytable (count, color) values
('$toarray[count]', '$toarray[searchkeywords]')");
Echo mysql_error();
}
}
I am not sure why, don't care. Here is a very simple pull from this table
insert into this table with the looped data.

Personally I'll get MySQL to do it for me using: insert into mytable (count,
color) select count(*) as count, searchkeywords from searchtable group by
searchkeywords order by count desc (see
http://dev.mysql.com/doc/refman/5.1/en/insert-select.html for more
information on INSERT ... SELECT)
Otherwise, you'll want to use mysql_fetch_assoc($result). Examples and
information can be found at http://php.net/mysql_fetch_assoc
