Ok, let me make sure I understand:
I see that you included brackets after the $out ($out[] = array instead of
$out = array).
Does this denote that the $out is now a zero-based array?
$out[0] is now an array that has $name, $srch, $sel and $case as single
elements in that array.
$out[1] is the next array with the same variable names, but different
values.
If I declare it as:
$out[] = array("name"=>$name, "srch"=>$srch, "sel"=>$sel,
"case"=>$case, $qvalues[] => array("vals" =>$vals, "valtypes" =>$valtypes));
can I access (for example) the $case variable in the 3rd $out array as
$out[2][$case]
or do I assign/access it as $out[2]["case"]?
Here is what I'd like to do: (and how would you declare this?)
I want 9 arrays (keyed as 0-8) for $out. (accessed as $out[0], $out[1],
etc.)
each of these arrays has individual $name, $srch, $sel, $case variables that
are strings.
I want to assign them individual values and access them as:
$out[0][$name] = "some_text";
echo $out[0][$name]; {shows the "some_text" string value of the $name
variable in the "zero-eth" element of the $out array}
$out[4][$case] {shows the string value of the $case variable in the "fourth"
element of the $out array}
A step further now:
As the fifth element in each of these 9 $out arrays I also need a sub-array
that has identical properties to the $out array,
but only has 2 elements in each of it's arrays.
I want to access them the same way:
$out[3][$qvalues[9][$vals] = "some_value";
will assign the text string "some_value" to the $vals variable inside
the10th $qvalue array for the 4th $out array.
I want to end up with something like this:
$out=array
[0]
$name=string
$srch=string
$sel=string
$case=string
$qvalues=array
[0]
$vals=string
$valtypes=string
[1]
$vals=string
$valtypes=string
[1]
$name=string
$srch=string
$sel=string
$case=string
$qvalues=array
[0]
$vals=string
$valtypes=string
[1]
$vals=string
$valtypes=string
{and so on for a few thousand times}
I guess one of the main issues is whether I can access (for example) the
$case variable in the $out array as [$case] or ["case"].
I don't need to initialize the string variables in the declaration of the
array, but do I still need to access them as
(for example) the ["case"] element of the $out array or can I access them as
[$case]?
Thanks for your help; I'm having to un-learn some of my C and Pascal, but
not too much.....<g>
