顯示所有檔案和資料夾 php檔案及資料夾操作（建立、刪除、移動、複製）

建立FileUtil.php文件，內容及呼叫方式如下：

<?<span>php

</span><span>/*</span><span>*
 * 操纵文件类
 * 
 * 例子：
 * FileUtil::createDir('a/1/2/3');                    测试建立文件夹 建一个a/1/2/3文件夹
 * FileUtil::createFile('b/1/2/3');                    测试建立文件        在b/1/2/文件夹下面建一个3文件
 * FileUtil::createFile('b/1/2/3.exe');             测试建立文件        在b/1/2/文件夹下面建一个3.exe文件
 * FileUtil::copyDir('b','d/e');                    测试复制文件夹 建立一个d/e文件夹，把b文件夹下的内容复制进去
 * FileUtil::copyFile('b/1/2/3.exe','b/b/3.exe'); 测试复制文件        建立一个b/b文件夹，并把b/1/2文件夹中的3.exe文件复制进去
 * FileUtil::moveDir('a/','b/c');                    测试移动文件夹 建立一个b/c文件夹,并把a文件夹下的内容移动进去，并删除a文件夹
 * FileUtil::moveFile('b/1/2/3.exe','b/d/3.exe'); 测试移动文件        建立一个b/d文件夹，并把b/1/2中的3.exe移动进去                   
 * FileUtil::unlinkFile('b/d/3.exe');             测试删除文件        删除b/d/3.exe文件
 * FileUtil::unlinkDir('d');                      测试删除文件夹 删除d文件夹

另一種調用方式：  推薦一個自己業餘時間開發的網盤搜尋引擎，360盤搜索（www.360panso.com） 以上就介紹了顯示所有檔案和資料夾 php檔案及資料夾操作（建立、刪除、移動、複製），包括了顯示所有檔案和資料夾方面的內容，希望對PHP教學有興趣的朋友有所幫助。
