Copy move file-PHP

A simple example of writing elfinder, extracting key member methods The implementation features are: Implement multi-file copy or move operations Note: In order to facilitate the test, some judgments have been made simple treatment. And in the directory where the program files are located Freshmen into a test folder as the destination folder. If the actual use needs to be modified. ? /** * Copy/move operation Simple example: >PHP5 * */ /** * Determine if the file exists * */ function _isfind ($filename) { Return @file_exists ($filename); } /** * Determine if a folder exists?
