需要php配置类，但找不到文件

Question

In my opinion I'm requiring all necessary files but I keep getting the error that one file is not found. All files are in the same folder.

This is my code for zConfig.php:

<?php
class zConfig {
    static $confArray;
    public static function read($name) {
        return self::$confArray[$name];
    }
    public static function write($name, $value) {
        self::$confArray[$name] = $value;
    }
}
?>

And this is my code for bd2.php:

require_once('zConfig.php');

/*
 * Write settings to the config
 */
zConfig::write('hostname', 'XXXX');
zConfig::write('database', 'XXXX');
zConfig::write('username', 'XXXX');
zConfig::write('password', 'XXXX');
zConfig::write('drivers', array(PDO::ATTR_PERSISTENT => true));

Finally, this is my code for a function within Product.php:

public function pdo_updateTip($which, $tiptext)
{
  require_once("bd2.php");
  try {
  $pdo = new PDO("mysql:host=".bd2::read('hostname').";dbname=".bd2::read('database')."", bd2::read('username'), bd2::read('password'), bd2::read('drivers'));
  $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

  $stmt = $pdo->prepare("UPDATE tip SET tip_text = :tiptext WHERE product_id='0' AND item LIKE :which");
  $stmt->execute(array(
    ':tiptext'   => $tiptext,
    ':which' => $which
  ));

echo $stmt->rowCount(); // 1
} catch(PDOException $e) {
  echo 'Error: ' . $e->getMessage();
}
    return true;
}

The error I'm getting when I load Product.php is this:

Fatal error: Class 'bd2' not found in /home/xxxxx/Product.php on line 45

Line 45 is the line where I first refer to bd2, here:

$pdo = new PDO("mysql:host=".bd2::read('hostname').";dbname=".bd2::read('database')."", bd2::read('username'), bd2::read('password'), bd2::read('drivers'));

Answer 1

I think that what you want to do is

$pdo = new PDO("mysql:host=".zConfig::read('hostname').";dbname=".zConfig::read('database')."", zConfig::read('username'), zConfig::read('password'), zConfig::read('drivers'));

bd2 is not a class and therefore it does not contain any static method read. It seems that it is just a file that sets the configuration for your database by using the zConfig::write method.
