Is it possible to define the size of the array instead of directly giving the input?
Like x is the array variable and it has the size of 10. So that I could pass the input.
You could try this:
However with my csh (tchs 6.22.01) using $arr:q to print array elements with quotes around them fails to print array elements that are blank. I had to append a single space instead.

array_slice
ARRAY_SLICE(3) 1 ARRAY_SLICE(3)array_slice - Extract a slice of the arraySYNOPSIS
array array_slice NULL (array $array, int $offset, [int $length], [bool $preserve_keys = false])
DESCRIPTION array_slice(3) returns the sequence of elements from the array $array as specified by the $offset and $length parameters.
PARAMETERS
o $array
- The input array.
o $offset
- If $offset is non-negative, the sequence will start at that offset in the $array. If $offset is negative, the sequence will
start that far from the end of the $array.
o $length
- If $length is given and is positive, then the sequence will have up to that many elements in it. If the array is shorter than
the $length, then only the available array elements will be present. If $length is given and is negative then the sequence will
stop that many elements from the end of the array. If it is omitted, then the sequence will have everything from $offset up until
the end of the $array.
o $preserve_keys
- Note that array_slice(3) will reorder and reset the numeric array indices by default. You can change this behaviour by setting
$preserve_keys to TRUE.
RETURN VALUES
Returns the slice.

| 5.2.4 | |
| | |
| | The default value of the $length parameter was |
| | changed to NULL. A NULL$length now tells the |
| | function to use the length of $array. Prior to |
| | this version, a NULL$length was taken to mean a |
| | zero length (nothing will be returned). |
| | |
| 5.0.2 | |
| | |
| | The optional $preserve_keys parameter was added. |

EXAMPLES
Example #1
array_slice(3) examples
<?php
$input = array("a", "b", "c", "d", "e");
$output = array_slice($input, 2); // returns "c", "d", and "e"
$output = array_slice($input, -2, 1); // returns "d"
$output = array_slice($input, 0, 3); // returns "a", "b", and "c"
// note the differences in the array keys
print_r(array_slice($input, 2, -1));
print_r(array_slice($input, 2, -1, true));
?>
The above example will output:
Array
(
[0] => c
[1] => d
)
Array
(
[2] => c
[3] => d
)
