我正在用 PHP 编写一个小型库,但我遇到了一些无法读取内置类的问题.例如:
I'm writing a small library in PHP and i'm having some problems with built-in classes not being read. For example:
namespace Woody;
class Test {
public function __construct() {
$db = new PDO(params);
}
}
这给了我:
PHP 致命错误:在/var/www/test.php 中找不到类WoodyPDO"
PHP Fatal error: Class 'WoodyPDO' not found in /var/www/test.php
这个:
namespace Woody;
use PDO;
或者:
$db = new PDO(params);
以防万一,类 PDO
不是您命名空间中的全限定名称,因此 PHP 会查找不可用的 WoodyPDO
.
Point in case is, that the class PDO
is not a full qualified name within your Namespace, so PHP would look for WoodyPDO
which is not available.
请参阅 名称解析规则文档 详细说明如何将类名解析为完全限定名.
See Name resolution rulesDocs for a detailed description how class names are resolved to a Fully qualified name.
