从javascript获取php函数值

Question

Allow me to preface this by saying that I did look over other answers, but I am still uncertain how to execute it.

Here is my problem:

I have a .txt file from which I am reading and parsing the meaning of a name (I know, DB is better, but this is what I was given). I wish to fetch the return value of my php function into my javascript function. How would I go about doing this?

PHP Code:

function populateMeaning() {
    $meanings = fopen("meanings.txt", "r") or die("Unable to open file");
    $meaning = "";

    $selectOption = $_POST['allnames'];

    while(!feof($meanings)) {
        $selectOption = strtoupper($selectOption);
        $line = fgets($meanings);

        if(strpos($line,$selectOption ) !== false) {
            $meaning = substr($line, strpos(0, ' '), strlen($line));
        }
    }

    return $meaning;
}

Javascript function in question:

function meaning(){

    document.getElementById("meaning").innerHTML = "hello";
}

So I have a div element titled "meaning" and I would like to replace it's inner html value. The string "hello" is currently simply a placeholder to make sure that the JS is called correctly.

jQuery Ajax简而言之，它是从前端（Javascript）到后端（PHP）值http://www.w3schools.com/jquery/ajax_ajax.asp或Google jQuery AJAX
