How to delete files or folders in PHP

Sometimes we need to use PHP to delete files and folders. PHP also has functions to implement. Below is a simple record of the Code to facilitate future persistence. First look at the code

<? Function deldir ($ dir) {// delete the files in the directory first: $ dh = opendir ($ dir); while ($ file = readdir ($ dh )) {if ($ file! = "." & $ File! = "..") {$ Fullpath = $ dir. "/". $ file; if (! Is_dir ($ fullpath) {unlink ($ fullpath) ;}else {deldir ($ fullpath) ;}} closedir ($ dh); // Delete the current folder: if (rmdir ($ dir) {return true;} else {return false ;}}?>

The unlink () function is used to delete objects. If the call succeeds, true is returned. If the call fails, false is returned. The rmdir () function is used to delete an empty directory. It tries to delete the directory specified by the dir. The directory must be empty and have the corresponding permissions.

One instance: delete all the ". svn" folders under a folder (including the content to be deleted ).

<? Phpfunction delsvn ($ dir) {$ dh = opendir ($ dir); // find all ". svn "folder: while ($ file = readdir ($ dh) {if ($ file! = "." & $ File! = ".. ") {$ Fullpath = $ dir. "/". $ file; if (is_dir ($ fullpath) {if ($ file = ". svn ") {delsvndir ($ fullpath);} else {delsvn ($ fullpath) ;}}} closedir ($ dh);} function delsvndir ($ svndir) {// delete the files in the directory first: $ dh = opendir ($ svndir); while ($ file = readdir ($ dh) {if ($ file! = "." & $ File! = ".. ") {$ Fullpath = $ svndir. "/". $ file; if (is_dir ($ fullpath) {delsvndir ($ fullpath);} else {unlink ($ fullpath) ;}} closedir ($ dh ); // Delete the directory folder if (rmdir ($ svndir) {return true;} else {return false; }}$ dir = dirname (_ FILE __); // echo $ dir; delsvn ($ dir);?>
