Get all values from checkboxes?

Is there an easy way to get all the values of multiple checkboxes, and store them into the database?

$fruit = $_POST['fruit'].",";
echo $fruit;
// if you selected apple and grapefruit it would display;
// apple,grapefruit,
<form method="post">
Select your favorite fruit:<br />
<input type="checkbox" name="fruit" value="apple" id="apple" /><label for="apple">Apple</label><br />
<input type="checkbox" name="fruit" value="pinapple" id="pinapple" /><label for="pinapple">Pinapple</label><br />
<input type="checkbox" name="fruit" value="grapefruit" id="grapefruit" /><label for="grapefruit">Grapefruit</label><br />
<input type="submit" name="go" />

Thanks in advance!

If you give the checkboxes the same name, ending in [], the values are returned as an array.

<input type="checkbox" name="fruit[]" value="apple" />
<input type="checkbox" name="fruit[]" value="grapefruit" />

Then in PHP ...

if( isset($_POST['fruit[]']) && is_array($_POST['fruit[]']) ) {
    foreach($_POST['fruit[]'] as $fruit) {
        // eg. "I have a grapefruit!"
        echo "I have a {$fruit}!";
        // -- insert into database call might go here

    // eg. "apple, grapefruit"
    $fruitList = implode(', ', $_POST['fruit[]']);
    // -- insert into database call (for fruitList) might go here.

PS. please forgive the obvious error, that this example will potentially shout "I have a apple" ... I didn't think to make the example smart enough to determine when to use "a", and when to use "an" :P
