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!
I have an SQL query that's pulled back user IDs as a set of columns. Rather than IDs, I want to use their names.
So I have an array of columns $col with values 1,7,3,12 etc and I've got an array $person... (3 Replies)
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 "-".
Example: 1,2,3,4-9,12,15,34-36,70
Now I need to get this from the user and go on each number and "Do something"... but when trying to do this as above... (2 Replies)

i need a bit of help on how to do this effectively in bash without a lot of extra looping or massive switch/case

for case 1, I want to stretch N to fit M

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:
#define MATRIX 10
int white_l1;
int white_l2;

Le sigh... Hopefully this will be the last time I have to ask for help on this topic. For a while now I've been working with a 1d array that holds 2d arrays. For reference you can view here. Now I'm just trying to loop through the elements with the following:

array_diff_key
ARRAY_DIFF_KEY(3) 1 ARRAY_DIFF_KEY(3)array_diff_key - Computes the difference of arrays using keys for comparisonSYNOPSIS
array array_diff_key (array $array1, array $array2, [array $...])
DESCRIPTION
Compares the keys from $array1 against the keys from $array2 and returns the difference. This function is like array_diff(3) except the
comparison is done on the keys instead of the values.
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 entries from $array1 whose keys are not present in any of the other arrays.
EXAMPLES
Example #1
array_diff_key(3) example
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.
<?php
$array1 = array('blue' => 1, 'red' => 2, 'green' => 3, 'purple' => 4);
$array2 = array('green' => 5, 'blue' => 6, 'yellow' => 7, 'cyan' => 8);
var_dump(array_diff_key($array1, $array2));
?>
The above example will output:
array(2) {
["red"]=>
int(2)
["purple"]=>
int(4)
}
NOTES
Note
This function only checks one dimension of a n-dimensional array. Of course you can check deeper dimensions by using
array_diff_key($array1[0], $array2[0]);.
