To get a slice of a bash array you can do stuff like
So your particular problem could be done with
If necessary, you could generalise to use a variable instead of the literal '3' and then complute how many elements you need from each slice; you can get the length of the array with ${#a[@]}.

Please can someone help to return the array elements from a function. Currently the problem I face is that tempValue stores the value in myValue as a string while I need an array of values to be returned instead of string.
Many Thanks,

array_intersect_assoc
ARRAY_INTERSECT_ASSOC(3) 1 ARRAY_INTERSECT_ASSOC(3)array_intersect_assoc - Computes the intersection of arrays with additional index checkSYNOPSIS
array array_intersect_assoc (array $array1, array $array2, [array $...])
DESCRIPTION array_intersect_assoc(3) returns an array containing all the values of $array1 that are present in all the arguments. Note that the keys
are used in the comparison unlike in array_intersect(3).
PARAMETERS
o $array1
- The array with master values to check.
o $array2
- An array to compare values against.
o $...
- A variable list of arrays to compare.
RETURN VALUES
Returns an associative array containing all the values in $array1 that are present in all of the arguments.
EXAMPLES
Example #1
array_intersect_assoc(3) example
<?php
$array1 = array("a" => "green", "b" => "brown", "c" => "blue", "red");
$array2 = array("a" => "green", "b" => "yellow", "blue", "red");
$result_array = array_intersect_assoc($array1, $array2);
print_r($result_array);
?>
The above example will output:
Array
(
[a] => green
)
In our example you see that only the pair "a" => "green" is present in both arrays and thus is returned. The value "red" is not returned
because in $array1 its key is 0 while the key of "red" in $array2 is 1, and the key "b" is not returned because its values are different in
each array.
The two values from the key => value pairs are considered equal only if (string) $elem1 === (string) $elem2 . In other words a strict type
check is executed so the string representation must be the same.
