如何使用MYSQLi和PHP显示信息?

I am using MYSQLi (from this website: http://codular.com/php-mysqli) and getting a blank page.

<html>
<body>  
    <h1>TEST21</h1>

    <?php

    error_reporting(E_ALL);  ini_set('display_errors', 1);

    $db = new mysqli('localhost', 'Brendan', 'password', 'Library');

    if($db->connect_errno > 0){
        die('Unable to connect to database [' . $db->connect_error . ']');
    }

    echo "STEP1";

    //STEP 2

    $sql = <<<SQL
        SELECT *
        FROM 'BOOK'
        WHERE 'ISBN10' > 0
    SQL;

    if(!$result = $db->query($sql)){
        die('There was an error running the query [' . $db->error . ']');
    }

    echo "STEP2";

    ?>

</body>

    The whacky thing with HEREDOC is that the closing identifier must not have any leading spaces (must not be indented). See the big warning here - http://php.net/manual/language.types.string.php#language.types.string.syntax.heredoc

    You're also using the wrong quote characters in your query. I'd simplify it all down to this...

    $sql = 'SELECT * FROM `BOOK` WHERE `ISBN10` > 0';
