求解Fatal error: Failed opening required 错误!
错误提示:
Warning: require_once(Abc.class.php) [function.require-once]: failed to open stream: No such file or directory in D:\myphpwww\Print.php on line 3
Fatal error: require_once() [function.require]: Failed opening required 'Abc.class.php' (include_path='.;C:\php6\pear') in D:\myphpwww\Print.php on line 3
Print.php 文件: //引入Abc.class.php文件
require_once 'Abc.class.php';
Abc.class.php文件:
class Abc{
//接收一个数并打印金字塔
public function printStar($n){
for($i=1;$i //先打印空格
for($k=1;$k echo" ";
//打印星号的个数
}
for($j=1;$j echo"*";
}
echo"";
}
}
}
?>
网上都说(1)找不到文件,是路径错误,可是引用路径没有错误啊,
(2)说是文件夹权限问题,可是d盘文件夹全给了,修改的。
望各位大神不吝赐教。
------解决方案--------------------
但在贴图中并没有看到 Print.php 文件
------解决方案--------------------
Print.php 與 Abc.class.php要放再同一目錄。
------解决方案--------------------
你名字寫錯了
截圖的是Abc.calss.php
而你include的是
Abc.class.php

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
