Would this work ? I have not tested it but it should work. save it as a file , give it execute permission and then use it as "script filename".
All the best. It's a simple logic but i think that would work for you.

LEARN ABOUT PHP
array_push
ARRAY_PUSH(3) 1 ARRAY_PUSH(3)
array_push - Push one or more elements onto the end of array
SYNOPSIS
int array_push (array &$array, mixed $value1, [mixed $...])
DESCRIPTION
array_push(3) treats $array as a stack, and pushes the passed variables onto the end of $array. The length of $array increases by the num-
ber of variables pushed. Has the same effect as:
<?php
$array[] = $var;
?>
Note
If you use array_push(3) to add one element to the array it's better to use $array[] = because in that way there is no overhead of
calling a function.
Note
array_push(3) will raise a warning if the first argument is not an array. This differs from the $var[] behaviour where a new array
is created.
PARAMETERS
o $array
- The input array.
o $value1
- The first value to push onto the end of the $array.
RETURN VALUES
Returns the new number of elements in the array.
EXAMPLES
Example #1
array_push(3) example
<?php
$stack = array("orange", "banana");
array_push($stack, "apple", "raspberry");
print_r($stack);
?>
The above example will output:
Array
(
[0] => orange
[1] => banana
[2] => apple
[3] => raspberry
)
SEE ALSO
array_pop(3), array_shift(3), array_unshift(3).
