fi php code example function create delete and copy operate manipulate document folder of move kind

復(fù)制代碼 代碼如下:



/**
* 操縱文件類
*
* 例子:
* FileUtil::createDir('a/1/2/3'); 測(cè)試建立文件夾 建一個(gè)a/1/2/3文件夾
* FileUtil::createFile('b/1/2/3'); 測(cè)試建立文件 在b/1/2/文件夾下面建一個(gè)3文件
* FileUtil::createFile('b/1/2/3.exe'); 測(cè)試建立文件 在b/1/2/文件夾下面建一個(gè)3.exe文件
* FileUtil::copyDir('b','d/e'); 測(cè)試復(fù)制文件夾 建立一個(gè)d/e文件夾,把b文件夾下的內(nèi)容復(fù)制進(jìn)去
* FileUtil::copyFile('b/1/2/3.exe','b/b/3.exe'); 測(cè)試復(fù)制文件 建立一個(gè)b/b文件夾,并把b/1/2文件夾中的3.exe文件復(fù)制進(jìn)去
* FileUtil::moveDir('a/','b/c'); 測(cè)試移動(dòng)文件夾 建立一個(gè)b/c文件夾,并把a(bǔ)文件夾下的內(nèi)容移動(dòng)進(jìn)去,并刪除a文件夾
* FileUtil::moveFile('b/1/2/3.exe','b/d/3.exe'); 測(cè)試移動(dòng)文件 建立一個(gè)b/d文件夾,并把b/1/2中的3.exe移動(dòng)進(jìn)去
* FileUtil::unlinkFile('b/d/3.exe'); 測(cè)試刪除文件 刪除b/d/3.exe文件
* FileUtil::unlinkDir('d'); 測(cè)試刪除文件夾 刪除d文件夾

復(fù)制代碼 代碼如下:


$fu = new FileUtil();
$fu->copyFile('a/1/2/3', 'a/1/2/4');
