我曾经问过这个代码有什么问题:
static $result = null;
if (isNull($result))
{
return $result;
}
经过大量的反对(问题消失了),问题是没有这样的东西叫做 isNull 函数。我们拥有的是 is_null
伟大的。我想知道我最初是如何使用 isNull 的。
原来它是自动完成工作。
现在我发现了为什么我输入 isNull。该功能实际存在。我按 ctrl 单击然后转到
/**
* Returns a PHPUnit_Framework_Constraint_IsNull matcher object.
*
* @return PHPUnit_Framework_Constraint_IsNull
* @since Method available since Release 3.3.0
*/
function isNull()
{
return PHPUnit_Framework_Assert::isNull();
}
/**
* Returns a PHPUnit_Framework_Constraint_IsTrue matcher object.
*
* @return PHPUnit_Framework_Constraint_IsTrue
* @since Method available since Release 3.3.0
*/
function isTrue()
{
return PHPUnit_Framework_Assert::isTrue();
}
它来自一个名为functions.php 的文件。我不知道这是什么问题

那是什么?知道该文件是如何进入我的 PHP 的吗?我从来不记得以前有那个文件。
我从来没有添加过这个框架。不是我知道的。然而它就在那里。它必须是一些强大的框架。
我怎么知道自动完成如何认为它是我的代码的一部分?我试过在资源管理器中显示,在导航器中显示,什么都没有。Windows 资源管理器中没有显示选项。
PhPUnit 一定是一个著名的框架,它在我不知道的情况下进入了我的代码。它是由 ZEND 自动安装的吗?
