PHP4; CCS 2.3
What's the correct syntax for removing multiple parameters using
CCRemoveParam() function?
Help says:
CCGetQueryString(CollectionName, RemoveParameters)
RemoveParameters = Array - Array of names which will be removed from the
resulting string.
How is this array to be formatted?

Can you look in function definition?
CCRemoveParam($querystring, $ParameterName)
First parameter - Query String(string type), where you want remove parameter with name $ParameterName.
Only one parameter can be removed with this function.
Simple example:
$QueryString = "page1.php?a=1&b=2&c=3";
$NewQueryString = CCRemoveParam($QueryString, "b");
Now $NewQueryString == "page1.php?a=1&c=3"

'Function Definition' clearly states that the parameters that are to be
removed is in an Array. This leads me to believe that more than one
parameter can be removed at a time. I'd like to know the format of that
Array (comma separated list, semi-colon list, what?).
I've figured out a way around this by:
$QueryString = CCGetQueryString("QueryString", "");
$pg = CCRemoveParam($QueryString, "Param1");
$pg = CCRemoveParam($pg, "Param2");
However, -If- $ParameterName is really an Array of values, then that would
eliminate the three or more lines of code required to remove two or more
parameters.

In you case can be used:
$QueryString = CCGetQueryString("QueryString", Array("Param1", "Param2"));

Yes, you are right. But function name are CCRemoveParam, not CCRemoveParams :)

Not sure what reference you are talking about. The function does a simple
preg_replace() ( for PHP) and Replace() (for ASP). Thus, the second
parameter cannot be an array, only a scalar value ( the name of one
parameter to be removed ).
Perhaps the documentation changed along the way and you have an outdated
version of it? I checked the online version and it's not described as an
array in therem which should be the most current definition.

I hit F1 in CCS v2.3.whatever and did a lookup of "CCRemoveParam". Says
'Array'. Am I the only one with this special version of the help files? :)

Yes, looks like you are...
I just searched for "CCRemoveParam" and I see 6 topics. Two of them are "CCRemoveParam Function (PHP)" and they don't mention arrays at all.
Only the other function that you mentioned above "CCGetQueryString" refers to arrays.

Yep, you're right. Myself and I were getting confused with ourselves.
I like Last Hero's suggestion of just making it a plural function
(CCRemoveParams). :)
Am I still stuck with using three lines of code to remove two or more
parameters, or is there a simpler, better way?

Sorry, I'm not too experienced with PHP and don't use those functions but maybe the 2nd post from Last Hero answers your question. If not then I guess you'd have to remove the parameters one at a time. Or maybe the support would have add'l suggestions.

I wrote a PHP function to handle arrays of parameters. Just add it to your
Common.php or, as I do, put it in a separate php file that is referenced by
an 'include()' in Common.php. That will make it callable from anywhere in
your application.
Now you only need to write one line of code anywhere you need to remove
several parameters. For convenience, I made sure it handles the case where
there is NOT an array (in which case, it works like CCRemoveParam). My
function is called in this manner:
RemoveParamMult($querystring, $arrayofparams).
Here are the details:
http://www.gotodon.com/ccbth/Features/ViewKB.asp?KBID=2083
A side note, there seems to be a bug in CCRemoveParam(), at least to me.
The first parameter of a querystring CANNOT be removed by CCRemoveParam().
Only parameters that begin with "&" will be removed. Since the first one
begins with "?", it is ignored.

I've been told by CCS support that CCRemoveParam() does work as it's
supposed to work. Evidently the querystring parameter is expected to NOT
include the "?" character, so if your page is
http://example.com/foobar.php?a=1&b=2&c=3
then the 'querystring' that CCRemoveParam() expects to see would be
a=1&b=2&c=3
so my example was flawed in the sense it treated the complete URL as the
querystring. In other words, the 'querystring' is actually supposed to be
everything AFTER the '?' in a URL.
