PHP implements the method of copying and moving files,

This article explains how PHP implements copying and moving files. Share to everyone for your reference. Specific as follows:

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.

The copy.php file is as follows:

<?php/** * Copy/move operation Simple example: &GT;PHP5 * *//** * Determine if the file exists * */function _isfind ($filename) {return @file_exists ($filename) ;} /** * Determine if a folder exists?  Simple processing: Only the root directory is judged * */function _isfinddir ($dir) {$ls = Scandir (dirname (__file__));  foreach ($ls as $val) {if ($val = = $dir) return TRUE; } return FALSE;} /** * Copy or Move * @param array of source folders: Simple processing: Use file name as element value * @param string destination folder * @param string operand: Move-Mobile; Copy-copy * @return bool */function _copy_move ($src = Array (), $DST = ", $op = ' move ') {if (! Is_array ($SRC)) {$SR  c = Array ($SRC);  }//Determine if the source file exists?    foreach ($src as $val) {if (_isfind ($val) = = = FALSE) {return _log (' src File not find ', $val); }}//Determine if the destination folder exists?  Generate//simple processing if not present: The actual application needs to modify if (_isfinddir ($dst) = = = FALSE) {@mkdir ($DST); }//Perform a move or copy operation foreach ($src as $val) {$_dst = $dst. '    /'. basename ($val); Determine if the destination file exists?    Presence is not allowed to operate if (_isfind ($_dst) = = = TRUE) {return _log (' DST file is exists ', $DST); } else if (Strpos ($DST, $val) = = =0) {return _log (' Unable to copy/move into itself ');  if (Strtolower ($op) = = = ' Move ') {if (! Rename ($val, $_dst)) {return _log (' Unable to move files ',      $val); }} else if (Strtolower ($op) = = = ' Copy ') {if (! _copy ($val, $_DST)) {return _log (' Unable to copy files '      , $val); }}} ' return ' success! ';} /** * Copy operation * */function _copy ($SRC, $DST) {if (! Is_dir ($SRC)) {if (! Copy ($SRC, $DST)) {return _log (' Unabl    E to copy Files ', $SRC);    }} else {mkdir ($DST);    $ls = Scandir ($SRC); for ($i = 0; $i < count ($ls); $i + +) {if ($ls [$i] = = '.
