PHP POST和Javascript？

This may sound confusing, but I am unsure as where to start looking for an answer. This is the scenario: I have a webpage with a table created using PHP and inside each cell is a randomly selected word. What I would like to do is allow a user to click one of the cells and it would return the definition of the word, and refresh the table/page. From what I found so far was to make use of _POST/_REQUEST, however I am unsure how to find out what the user clicked, and pass that into a function to find the definition. Is my logic correct here, how would you go about this? I was thinking of having an onclick function to identify the element clicked, but don't know how to handle it.

<body>
<form method="post" action="
<table border="1">

<?php

$f="/words.txt";    //definitions also included in this file
$o=file($f);
$len=count($o);

$i=0;
while( $i < 18){
    $rnum= rand(2,$len);
    $rword= $o[$rnum];
    $piece= explode(" ",$rword);      //get just the word on the line

    if($i%3==0){
            echo "<tr>";
    }
echo "<td id='$i' onclick='about()'>".$piece[2]."</td>";
    $i++;
    if($i%3==0){
        echo "</tr>";
    }
}
?>

</table>
</body>
</html>

    The simplest thing you may done without need to any javascript is to make number forms equals to the number of cells you have. It is something like the following:

    //Remove the form tag
<table border="1">

<?php

$f="/words.txt";    //definitions also included in this file
$o=file($f);
$len=count($o);

$i=0;
while( $i < 18){
    $rnum= rand(2,$len);
    $rword= $o[$rnum];
    $piece= explode(" ",$rword);      //get just the word on the line

    if($i%3==0){
            echo "<tr>";
    }
?>
<td id='<?php echo $i; ?>'><form method="post"><input type="hidden" name="word" value="<?php echo $piece[2];?> /><input type="submit" value="<?php echo $piece[2];?> /></form></td>;
<?php
    $i++;
    if($i%3==0){
        echo "</tr>";
    }
}
?>

</table>

    By this way you have a submit button for each word you have that submit its own form's hidden element with the name word to be precessed on the server side.
