Realize multiple file copy or move operations

Note: In order to facilitate testing, some judgments have been briefly processed. And a new test folder will be generated as the destination folder in the directory where the program file is located
. Modification is required if actual use is required.
copy.php file is as follows:

PHP5 **/ /*** Determine whether the file exists **/ function _isFind($filename) { return @file_exists($filename) ; } /*** Determine whether the folder exists? Simple processing: only judge the root directory **/ function _isFindDir($dir) { $ls = scandir(dirname(__FILE__)); foreach ($ls as $val) { if ($val == $dir) return TRUE; } return FALSE; } /*** Copy or move * * @param array Source folder array: simple processing: use the file name as the element value * @param string destination folder * @param string Operands: move - move; copy - copy * @return bool*/ function _copy_move($src = array(), $dst = '', $op = 'move') { if ( ! is_array($src)) { $src = array ($src); } //Check whether the source file exists? foreach ($src as $val) { if ( _isFind($val) === FALSE) { return _log('Src file not find', $val); } } //Determine whether the destination folder exists? If it does not exist, generate it //Simple processing: Actual application needs to modify if (_isFindDir($dst) === FALSE) { @mkdir($dst); } //Execute the move Or copy operation foreach ($src as $val) { $_dst = $dst.'http://www.jb51.net/'.basename($val); // Determine whether the destination file exists? The operation is not allowed if it exists. 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 ('Unable to copy files', $src); } } else { mkdir($dst); $ls = scandir($src); for ($i = 0; $i < count($ls); $i ) { if ($ls[$i] == '.' OR $ls[$i] == '..') continue; $_src = $src.'http://www.jb51.net/'. $ls[$i]; $_dst = $dst.'http://www.jb51.net/'.$ls[$i]; if ( is_dir($_src)) { if ( ! _copy($_src, $_dst)) { return _log('Unable to copy files', $_src); } } else { if ( ! copy($_src, $_dst)) { return _log('Unable to copy files', $_src); } } } } return TRUE; } /*** Logging **/ function _log($msg, $arg = '') { if ($arg != '') { $msg = "date[".date(' Y-m-d H:i:s')."]\tmsg[".$msg."]\targ[".$arg."]\n"; } else { $msg = "date[".date('Y-m-d H:i:s')."]\tmsg[".$msg."]\n"; } echo $msg; return @file_put_contents('copy.log', $msg, FILE_APPEND); } /*** Example * 1. The array parameter of $src needs to be modified; 2. The third parameter of _copy_move can be modified to test the move/copy operation separately **/ $src = array('img', 'min', 'phpinfo.php'); $dst = 'test'; var_dump(_copy_move($src, $dst, 'copy')); /*end of php*/
