You cannot do that. An array element can hold a scalar, i.e. a string, a number, or a reference. The reference can be a "handle" to another array, so you can say
but that's probably not what you want; printing $KS[1] will produce something like ARRAY (0x1CC01BED) and you have to use ${$KS[1]}[0] to access the first element of @kr, etc.
Another option would be to use splice to replace $KS[1] with all the elements of @kr, meaning $KS[1] will be the first element or @kr, $KS[2] will be the second, etc. http://perldoc.perl.org/functions/splice.html

Suppose there are two arrays of arrays:
@A = ( , , , );
@B = ( , , , , );
For each of $A, $A, $A..., I want to find the corresponding one in @B (match the letter, like $A eq $B), and print out both the second item, for example, $A and $B.
How can I do this in perl? grep + map? Hope I... (1 Reply)
PHP question...I posted this on the Web Development forum, but maybe this is a better place!

Hi All
I need to get <STDIN> from a user. the <STDIN> is a range of number delimited by "," (comma) and can be with range delimited by "-".

I hate I'm asking for help again. Unfortunately it seems there just aren't any links I can find on making an array that holds a bunch of two dimensional arrays. Maybe my google-fu is lacking. Basically I have a header file like this:

int white_l2;

Corona688 was great in helping me learn how to create arrays that hold other two dimensional array here. Unfortunately I didn't think ask about how to implement or call them. Basically, I'm trying to call an array of two-dimensional arrays like this:

array_replace
ARRAY_REPLACE(3) 1 ARRAY_REPLACE(3)array_replace - Replaces elements from passed arrays into the first arraySYNOPSIS
array array_replace (array $array1, array $array2, [array $...])
DESCRIPTION array_replace(3) replaces the values of $array1 with values having the same keys in each of the following arrays. If a key from the first
array exists in the second array, its value will be replaced by the value from the second array. If the key exists in the second array, and
not the first, it will be created in the first array. If a key only exists in the first array, it will be left as is. If several arrays are
passed for replacement, they will be processed in order, the later arrays overwriting the previous values.
array_replace(3) is not recursive : it will replace values in the first array by whatever type is in the second array.
PARAMETERS
o $array1
- The array in which elements are replaced.
o $array2
- The array from which elements will be extracted.
o $...
- More arrays from which elements will be extracted. Values from later arrays overwrite the previous values.
RETURN VALUES
Returns an array, or NULL if an error occurs.
EXAMPLES
Example #1
array_replace(3) example
<?php
$base = array("orange", "banana", "apple", "raspberry");
$replacements = array(0 => "pineapple", 4 => "cherry");
$replacements2 = array(0 => "grape");
$basket = array_replace($base, $replacements, $replacements2);
print_r($basket);
?>
The above example will output:
Array
(
[0] => grape
[1] => banana
[2] => apple
[3] => raspberry
[4] => cherry
)
