Thanks so much Jarred. It helps me learn more when there's an
explaination on how the code works. I'll play around with it, change
it a bit and give that a try. Take care...

Incidentally, ponder this:
<code>
function shortGetNewQueryString($arr,$merge) {
return array_merge($arr,$merge);
}
echo('<pre>');
// Let's do one new cID, new GET key/value
$query = Array('cID'=>42,'freudian'=>'slip');
$go = shortGetNewQueryString($_GET,$query);
print_r($go);
// Let's do one new cID, new GET key/value
$query = Array('cID'=>9-002,'footloose'=>'fancy free');
$go = shortGetNewQueryString($go,$query);
print_r($go);
// Let's do one new cID, new GET key/value
$query = Array('cID'=>493,'fugged'=>'dhaboutit');
$go = shortGetNewQueryString($go,$query);
print_r($go);
// Let's do one new cID, new GET key/value
$query = Array('cID'=>A4,'longlongtimeago'=>'in a galaxy far, far
away');
$go = shortGetNewQueryString($go,$query);
print_r($go);
echo('</pre>');

By the way, when you run that code, pay special attention to the
second test. Very very tricky entry anomaly... Wuffuh!
Pay attention to how short that new code is
( shortGetNewQueryString() ). It's certainly arguable you don't even
need to wrap it in a function. Consider:
<code>
// This is the best version, I believe: brief and simple.
function mediumGetNewQueryString ($arr,$add) {
foreach ($add as $key=>$val) {
$arr[$key] = $val;
}
return $arr;
}
echo('<pre>');
print_r( mediumGetNewQueryString($_GET,$query) );
echo('<pre>');
</code>
And then, of course, a number of shortcuts may be used to obscurify and
mystify your code for later puzzling, head-scratchedness.
This is, of course, exactly comparable to all the other example
methods:
<code>
// Hard to read, ie, needless brevity
function annoyingGetNewQueryString ($arr,$add) {
foreach ($add as $key=>$val) $arr[$key] = $val;
return $arr;
}
echo('<pre>');
print_r( annoyingGetNewQueryString($_GET, $query) );
echo('</pre>');
</code>
Caution: Using array_merge, though, will overwrite keynames, but NOT
numerical items. You can't auto-map over numerical keys with array_merge(),
apparently.
Consider:
<code>
$array = Array(
[0] => 'moe'
[1] => 'curly',
[2] => 'larry'
);
// Is equivalent to ~
$array = Array();
$array[] 'moe';
$array[] 'curly';
$array[] 'larry';
// Is equivalent to ~
$array = Array();
array_push($array, 'moe');
array_push($array, 'curly');
array_push($array, 'larry');
</code>
When you add a numerical array in php, it is added to the stack as a new
item, or push. Essentially,
$array = Array('item1')
$array[] = 'item2' eq ~ "Array('item1','item2')"
And then when you call on the array, it
{ get Array as Numerically-Indexed Set } eq ~ split($array,$token=',') eq ~
({ [0] => 'item' , [1] = 'item2' })
So an array on a stack can be represeted in memory as a comma-delimited
numerically-indexed list, eg, 'item','item2'
