I have using a 'switch' to retrieve the name of the website section through
sending a 'section' integer...
function title($section)
{
switch ($section)
{
case 0:
$output = "Introducti on";
case 1:
$output = "login";
case 2:
$output = "choose_dat e";
case 3:
$output = "am_pm";
case 4:
$output = "hour";
case 5:
$output = "choose_tim e";
case 6:
$output = "slots";
case 7:
$output = "add_notes" ;
case 8:
$output = "confirm";
case 9:
$output = "booked";
default:
$output = "Introducti on";
}
return $output;
}
However, no matter what number I sent to the command I am getting the
default case out (Introduction).
This seems like a very simple command, where am I going wrong???
Many thanks

switch's cases fall through to next case, so that you can do
switch($a) {
case 0:
case 1:
whatever();
break;
case 2:
case 3:
somethingelse() ;
break;
default:
nomatch();
break;
}
Here, whatever() will be called when $a is 0 or 1; somethingelse() will
be called when $a is 2 or 3; and nomatch() will be called at all other
times.
In your script, when $section is 0, it will set $output to
"Introducti on", then to "login", then ..., and finally to "Introducti on"
again.
You need break statements in each case to stop the script from going on
to next case statements.

You already got the switch/break answer, but if all you want to do is assign
a string constant, you could also have used an array filled with the 10
strings you need and use the $a as the index.
$arr = array("Introduc tion","login"," choose_date","a m_pm","hour"); // add
the other 5 as well of course...
$output = $arr [$a];
Less typing, and I think more elegant as well. I haven't tried which
solution is faster at runtime. My guess would be the array version too.

Now, I am trying to calculate, with each sort, how many times during
the sort the array elements are compared and swapped.

Hello!
I have below a for loop and a switch in the for loop.
I have also a enum called colBlowStep with some values.
I have also an array called m_columnBlowStep with some strings.
All items in the array m_columnBlowStep is string because I have used
ToString on each enum item as you can see.
I want to use enum in the case statment in the switch.
I know I can use string but I rather want to use enum.
