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.

Regds,

LOOK WOKING...BUT can I specify any word to delete? such as orange..and it can delete the 2nd duplicated of "orange" only.

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)
