I am trying to define number of array based on constant derived during execution phase of a script. Here is what i am trying..
My question is in the second part, where i am dynamically generating the Array name & then assigning element values to it depending on the counter.
For example:
For the first loop, i give two LUN numbers, say 10 & 11. So, my first array would be
my_lun[0]=10
my_lun[1]=11
For the second loop, since in generating the array name based on the LUN name & i give 3 values as elements for each array. So, my array should look like ( this is my question),
I'm attempting to populate an array in ksh using the following command:

SELECT_INVOICE is a function that executes the SQL query.
Problem: Some of the invoice numbers have alpha characters with spaces(example: OVEN MICRO). The Korn shell is treating... (1 Reply)
I read it is possible to provide values for an array with the -A option to the read statement; however, I have not been able to get this to work. When I execute a script with the -A option to the read statement, the shell complains that it is an illegal option. If this works, can someone provide... (5 Replies)

Hello,
I'm currently messing around with arrays for the first time in scripting (Unix Korn Shell). All I'm trying to do right now before I make things complicated is read through and print out to screen whether the read file is or is not a directory.

LEARN ABOUT PHP
count
COUNT(3) 1 COUNT(3)count - Count all elements in an array, or something in an objectSYNOPSIS
int count (mixed $array_or_countable, [int $mode = COUNT_NORMAL])
DESCRIPTION
Counts all elements in an array, or something in an object.
For objects, if you have SPL installed, you can hook into count(3) by implementing interface Countable. The interface has exactly one
method, Countable::count, which returns the return value for the count(3) function.
Please see the Array section of the manual for a detailed explanation of how arrays are implemented and used in PHP.
PARAMETERS
o $array_or_countable
- An array or Countable object.
o $mode
- If the optional $mode parameter is set to COUNT_RECURSIVE (or 1), count(3) will recursively count the array. This is particu-
larly useful for counting all the elements of a multidimensional array.
Caution
count(3) can detect recursion to avoid an infinite loop, but will emit an E_WARNING every time it does (in case the array
contains itself more than once) and return a count higher than may be expected.
RETURN VALUES
Returns the number of elements in $array_or_countable. If the parameter is not an array or not an object with implemented Countable inter-
face, 1 will be returned. There is one exception, if $array_or_countable is NULL, 0 will be returned.
Caution
count(3) may return 0 for a variable that isn't set, but it may also return 0 for a variable that has been initialized with an empty
array. Use isset(3) to test if a variable is set.
EXAMPLES
Example #1
count(3) example
<?php
$a[0] = 1;
$a[1] = 3;
$a[2] = 5;
$result = count($a);
// $result == 3
$b[0] = 7;
$b[5] = 9;
$b[10] = 11;
$result = count($b);
// $result == 3
$result = count(null);
// $result == 0
$result = count(false);
// $result == 1
?>
Example #2
Recursive count(3) example
<?php
$food = array('fruits' => array('orange', 'banana', 'apple'),
'veggie' => array('carrot', 'collard', 'pea'));
// recursive count
echo count($food, COUNT_RECURSIVE); // output 8
// normal count
echo count($food); // output 2
?>
