Although you already selected an answer, don't forget this piece of script may fail if the POST values are not arrays. You can overcome this with a small piece of code:

$something = is_array($_POST['something']) ? $_POST['something'] : array();
$example = is_array($_POST['example']) ? $_POST['example'] : array();

/* Get all the keys from both arrays
 * If they don't share the keys, none will be lost
 */
$keys = array_merge(array_keys($something),array_keys($example));
$keys = array_unique();

if (count($keys)) {
    $sql = 'INSERT INTO table (row, row2) VALUES ';
    $values = array();

    foreach ($keys as $key) {
        // Single quotes for PHP, we are not expanding variables
        // If the element cannot be converted into a string, don't show the error on screen
        $values[] = '("' . @mysql_real_escape_string($something[$key]) . '","' . @mysql_real_escape_string($example[$key]) . '")';
    }

    $sql .= implode(',', $values);
    mysql_query($sql);
}
