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_merge
ARRAY_MERGE(3) 1 ARRAY_MERGE(3)array_merge - Merge one or more arraysSYNOPSIS
array array_merge (array $array1, [array $...])
DESCRIPTION
Merges the elements of one or more arrays together so that the values of one are appended to the end of the previous one. It returns the
resulting array.
If the input arrays have the same string keys, then the later value for that key will overwrite the previous one. If, however, the arrays
contain numeric keys, the later value will not overwrite the original value, but will be appended.
Values in the input array with numeric keys will be renumbered with incrementing keys starting from zero in the result array.
PARAMETERS
o $array1
- Initial array to merge.
o $...
- Variable list of arrays to merge.
RETURN VALUES
Returns the resulting array.
EXAMPLES
Example #1
array_merge(3) example
<?php
$array1 = array("color" => "red", 2, 4);
$array2 = array("a", "b", "color" => "green", "shape" => "trapezoid", 4);
$result = array_merge($array1, $array2);
print_r($result);
?>
The above example will output:
Array
(
[color] => green
[0] => 2
[1] => 4
[2] => a
[3] => b
[shape] => trapezoid
[4] => 4
)
Example #2
Simple array_merge(3) example
<?php
$array1 = array();
$array2 = array(1 => "data");
$result = array_merge($array1, $array2);
?>
Don't forget that numeric keys will be renumbered!
Array
(
[0] => data
)
If you want to append array elements from the second array to the first array while not overwriting the elements from the first
array and not re-indexing, use the + array union operator:
<?php
$array1 = array(0 => 'zero_a', 2 => 'two_a', 3 => 'three_a');
$array2 = array(1 => 'one_b', 3 => 'three_b', 4 => 'four_b');
$result = $array1 + $array2;
var_dump($result);
?>
The keys from the first array will be preserved. If an array key exists in both arrays, then the element from the first array will
be used and the matching key's element from the second array will be ignored.
array(5) {
[0]=>
string(6) "zero_a"
[2]=>
string(5) "two_a"
[3]=>
string(7) "three_a"
[1]=>
string(5) "one_b"
[4]=>
string(6) "four_b"
}
Example #3
array_merge(3) with non-array types
<?php
$beginning = 'foo';
$end = array(1 => 'bar');
$result = array_merge((array)$beginning, (array)$end);
print_r($result);
?>
The above example will output:
Array
(
[0] => foo
[1] => bar
)
