I am calling this function which is modifying an array by reference:

function addWord(&$words, $wordIndex, $word) { $words[$wordIndex] = $word; }

At the function call,

addWord(&$words, $wordsIndex, $word);

($words is used only during the function call)

doesn't work. How do I make this or a similar functionality work? I want the addWord to be a separate function.
