Hi,
I am not that good at Perl.
But here's what I wanna do.
I want to create a hash where the keys would point to different arrays. This is what I have tried to do but in vain :(
@arr=(1,2,3);
@arr1=(3,2,1);

Hello experts. I'm having problems with a snippet of code.
I was hoping to get help/advice to correct.
A file that this script parses has changed to the point where
I can no longer use a scalar, it looks as though I need to
create an array for a hash of hashes below.

array_intersect_key
ARRAY_INTERSECT_KEY(3) 1 ARRAY_INTERSECT_KEY(3)array_intersect_key - Computes the intersection of arrays using keys for comparisonSYNOPSIS
array array_intersect_key (array $array1, array $array2, [array $...])
DESCRIPTION array_intersect_key(3) returns an array containing all the entries of $array1 which have keys that are present in all the arguments.
PARAMETERS
o $array1
- The array with master keys to check.
o $array2
- An array to compare keys against.
o $...
- A variable list of arrays to compare.
RETURN VALUES
Returns an associative array containing all the entries of $array1 which have keys that are present in all arguments.
EXAMPLES
Example #1
array_intersect_key(3) example
<?php
$array1 = array('blue' => 1, 'red' => 2, 'green' => 3, 'purple' => 4);
$array2 = array('green' => 5, 'blue' => 6, 'yellow' => 7, 'cyan' => 8);
var_dump(array_intersect_key($array1, $array2));
?>
The above example will output:
array(2) {
["blue"]=>
int(1)
["green"]=>
int(3)
}
In our example you see that only the keys 'blue' and 'green' are present in both arrays and thus returned. Also notice that the values for
the keys 'blue' and 'green' differ between the two arrays. A match still occurs because only the keys are checked. The values returned are
those of $array1.
The two keys from the key => value pairs are considered equal only if (string) $key1 === (string) $key2 . In other words a strict type
check is executed so the string representation must be the same.
