Hope this helps:

Code:
typeset -i x=5
typeset -i i=0
typeset -i j=0
typeset -i y=0
array[0]=1
array[1]=2
array[2]=2
array[3]=3
array[4]=4

i=0
while (( i < x )); do

        (( j = i + 1 ))
        while (( j < x )); do
                if [ ${array[i]} = ${array[j]} ]; then
                        break
                fi

                (( j = j + 1 ))
        done

        if [ $j = $x ]; then
                newarr[y]=${array[i]}
                (( y = y + 1 ))
        fi
        (( i = i + 1 ))
done

i=0
while (( i < y )); do

        echo "${newarr[i]}"

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). PHP Documentation Group ARRAY_PUSH(3)
