创建FileUtil.php文件,内容及调用方式如下:
<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 </span><span>*/</span><span>class</span><span> FileUtil { </span><span>/*</span><span>* * 建立文件夹 * * @param string $aimUrl * @return viod </span><span>*/</span><span>function</span> createDir(<span>$aimUrl</span><span>) { </span><span>$aimUrl</span> = <span>str_replace</span>('', '/', <span>$aimUrl</span><span>); </span><span>$aimDir</span> = ''<span>; </span><span>$arr</span> = <span>explode</span>('/', <span>$aimUrl</span><span>); </span><span>$result</span> = <span>true</span><span>; </span><span>foreach</span> (<span>$arr</span><span>as</span><span>$str</span><span>) { </span><span>$aimDir</span> .= <span>$str</span> .

另一种调用方式:
<span>$fu</span> = <span>new</span><span> FileUtil(); </span><span>$fu</span>->copyFile('a/1/2/3', 'a/1/2/4');
