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.

LEARN ABOUT PHP
array_diff_assoc
ARRAY_DIFF_ASSOC(3) 1 ARRAY_DIFF_ASSOC(3)array_diff_assoc - Computes the difference of arrays with additional index checkSYNOPSIS
array array_diff_assoc (array $array1, array $array2, [array $...])
DESCRIPTION
Compares $array1 against $array2 and returns the difference. Unlike array_diff(3) the array keys are also used in the comparison.
PARAMETERS
o $array1
- The array to compare from
o $array2
- An array to compare against
o $...
- More arrays to compare against
RETURN VALUES
Returns an array containing all the values from $array1 that are not present in any of the other arrays.
EXAMPLES
Example #1
array_diff_assoc(3) example
In this example you see the "a" => "green" pair is present in both arrays and thus it is not in the output from the function.
Unlike this, the pair 0 => "red" is in the output because in the second argument "red" has key which is 1.
<?php
$array1 = array("a" => "green", "b" => "brown", "c" => "blue", "red");
$array2 = array("a" => "green", "yellow", "red");
$result = array_diff_assoc($array1, $array2);
print_r($result);
?>
The above example will output:
Array
(
[b] => brown
[c] => blue
[0] => red
)
Example #2
array_diff_assoc(3) example
Two values from key => value pairs are considered equal only if (string) $elem1 === (string) $elem2 . In other words a strict check
takes place so the string representations must be the same.
<?php
$array1 = array(0, 1, 2);
$array2 = array("00", "01", "2");
$result = array_diff_assoc($array1, $array2);
print_r($result);
?>
The above example will output:
Array
(
[0] => 0
[1] => 1
)
NOTES
Note
This function only checks one dimension of a n-dimensional array. Of course you can check deeper dimensions by using, for example,
array_diff_assoc($array1[0], $array2[0]);.
Note
Ensure you pass arguments in the correct order when comparing similar arrays with more keys. The new array should be the first in
the list.
