本文实例讲述了php实现csv文件的导入和导出类。分享给大家供大家参考。具体如下：
csv_array = $param_arr; $this->path = $path; $this->column = $column; } /** * 导出 * */ public function export(){ if(empty($this->csv_array) || empty($this->column)){ return false; } $param_arr = $this->csv_array; unset($this->csv_array); $export_str = implode(',',$param_arr['nav']).n; unset($param_arr['nav']); //组装数据 foreach($param_arr as $k=>$v){ foreach($v as $k1=>$v1){ $export_str .= implode(',',$v1).n; } } //将$export_str导出 header( cache-control: public ); header( pragma: public ); header(content-type:application/vnd.ms-excel); header(content-disposition:attachment;filename=txxx.csv); header('content-type:application/octet-stream'); ob_start(); // $file_str= iconv(utf-8,'gbk',$export_str); ob_end_clean(); echo $export_str; } /** * 导入 * */ public function import($path,$column = 3){ $flag = flase; $code = 0; $msg = '未处理'; $filesize = 1; //1mb $maxsize = $filesize * 1024 * 1024; $max_column = 1000; //检测文件是否存在 if($flag === flase){ if(!file_exists($path)){ $msg = '文件不存在'; $flag = true; } } //检测文件格式 if($flag === flase){ $ext = preg_replace(/.*.([^.]+)/,$1,$path); if($ext != 'csv'){ $msg = '只能导入csv格式文件'; $flag = true; } } //检测文件大小 if($flag === flase){ if(filesize($path)>$maxsize){ $msg = '导入的文件不得超过'.$maxsize.'b文件'; $flag = true; } } //读取文件 if($flag == flase){ $row = 0; $handle = fopen($path,'r'); $dataarray = array(); while($data = fgetcsv($handle,$max_column,,)){ $num = count($data); if($num array('xiaohai1','123456','xiaohai1@zhongsou.com'), 1=>array('xiaohai2','213456','xiaohai2@zhongsou.com'), 2=>array('xiaohai3','123456','xiaohai3@zhongsou.com')));$column = 3;$csv = new csv($param_arr, $column);//$csv->export();$path = 'c:\documents and settings\administrator\temp\txxx.csv';$import_arr = $csv->import($path,3);var_dump($import_arr);?>
希望本文所述对大家的php程序设计有所帮助。
