Description: ------------ When we try to remove recursively a dir on a unix server this error appear: "Uninitialized string offset: 0" (on windows it works) Test script: --------------- We change your _rm_dir_recursive function as below (see "/**/" comments) and now the code works on any plataform function _rm_dir_recursive($dir) { if (substr($dir, (strlen($dir) - 1), 1) != "/") { return $this->raiseError("Directory name '$dir' is invalid, has to end with '/'", NET_FTP_ERR_REMOTEPATHNODIR); } $file_list = $this->_ls_files($dir); foreach ($file_list as $file) { $file = $dir.$file["name"]; $res = $this->rm($file); if ($this->isError($res)) { return $res; } } $dir_list = $this->_ls_dirs($dir); foreach ($dir_list as $new_dir) { /** * in past the test isn't the position 'name' of the array but the entire array and the loop never ends. now works fine * **/ if ($new_dir['name'] == '.' || $new_dir['name'] == '..') { continue; } $new_dir = $dir.$new_dir["name"]."/"; //echo $new_dir."<br/>"; $res = $this->_rm_dir_recursive($new_dir); if ($this->isError($res)) { return $res; } } $res = $this->_rm_dir($dir); if (PEAR::isError($res)) { return $res; } else { return true; } } Expected result: ---------------- remove recursively a directory Actual result: -------------- with the patch the script works fine
