PHP file and folder operations (create, delete, move, copy ),

PHP file and folder operations (create, delete, move, copy ),

Create a FileUtil. php file. The content and calling method are as follows:

<? Example of php/*** file control **: * FileUtil: createDir ('A/1/2/3'); Create a folder named a/1/2/3 * FileUtil:: createFile ('B/1/2/3'); Create a 3 File * FileUtil under the B/1/2/folder to test the file creation :: createFile ('B/1/2/3.exe'); Create a 3.exe file * FileUtil: copyDir ('B', 'd/E') under file B/1/2/folder '); create a d/e folder in the copy folder and copy the content in the B folder to * FileUtil: copyFile ('B/1/2/3.exe ', 'B/B/3.exe'); Create a B/B folder and copy the 3.exe file in the B/1/2 folder to * FileUtil: moveDir ('A /', 'B/C'); test migration Create a folder B/c, move the content in folder a, and delete the folder * FileUtil: moveFile ('B/1/2/3.exe ', 'B/d/3.exe'); test the mobile file to create a B/d folder, and move 3.exe in B/1/2 to * FileUtil :: unlinkFile ('B/d/3.exe'); test the function of deleting the B/d/3.exe file * FileUtil: unlinkDir ('D '); test deleting a folder and deleting a d folder */class FileUtil {/*** create a folder ** @ param string $ aimUrl * @ return viod */function createDir ($ aimUrl) {$ aimUrl = str_replace ('', '/', $ aimUrl); $ aimDir =''; $ arr = explode ('/', $ AimUrl); $ result = true; foreach ($ arr as $ str) {$ aimDir. = $ str.

Another call method:

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