Roku Developer Program

PHP has many useful built-in array functions that I miss when developing Roku channels with Brightscript. So, I decided to write (and share) a couple equivalents in Brightscript. Please feel free to use these as is and/or comment on how your versions are better/more efficient than what I've posted:)

function explode(delimeter, string)
    result = []
    position1 = 1
    position2 = Instr(position1, string, delimeter)
    delimeterLen = Len(delimeter)
    stringLen = Len(string)

    while position2 <> 0
        result.Push(Mid(string, position1, position2 - position1))
        position1 = position2 + delimeterLen
        position2 = Instr(position1, string, delimeter)
    end while

    if position1 <= stringLen
        result.Push(Mid(string, position1))
    else if position1 - 1 = stringLen
        result.Push("")
    end if

    return result
end function

function implode(glue, pieces)
    result = ""
    for each piece in pieces
        if result <> ""
            result = result + glue
        end if
        result = result + piece
    end for

    return result
end function

I believe the Tokenize() method on a string will do what your explode function does.

You could also try roRegEx::Split()
