PHP Code:

<?php

    // Fig 1.1

    $myVar = "FlashMove";

    echo "&myVar=$myVar"; // Output "&myVar=FlashMove"

?>

In the Fig.1.1, line 2 shows an "&" character. The "&" is an operator to show seperation in variables for the Interpreter. It is not necessary for the first and/or only variable being loaded to the Interpreter, but it is good practice too use.
Once the variables are loaded to the Interpreter and parsed for seperation... the "&" is then ignored.

Let's use a HitCounter as good start on how we can load and send data to and from a Text File.

PHP Code:

    /* Hit Count Script- hit_count.php*/

    function count_hit () {

        // Read File

        $file = "temp.txt";

        $fp = fopen($file, "r");

        $reading = fread($fp,2000);

        fclose($fp);

            

        // Increment

        $reading++;

        echo "&hitcount=$reading";

        

        // Write File

        $fp = fopen($file, "w");

        $writeing = fwrite($fp,$reading);

        fclose($fp);

    }

    switch ($action) {

        case "countHit":

            count_hit();

        break;

        default:

            die();

        break;

    } 

Actionscript:

hitCountVar = new LoadVars();
with(hitCountVar) {
	action = "countHit";
	sendAndLoad("hit_count.php", hitCountVar, "GET")
}

hitCountVar.onLoad = function () {
	trace(this.hitcount); // PHP Response
}

.. to be continue
