导入php利用phpexcel插件实现数据的导入和导出(支持csvxlsxlsx格式和超过26个字段列)

一、导入这其中show_msg和logFile是自定义函数

/**

* 方法名 : excelToTable

* 作用 : 【私有】将excel数据导入数据表中

* @param1  file用户上传的文件信息

* @param2  tableid用来区别是哪张表 1-statistics_rawdata_pct 2-statistics_rawdata_apply 3-statistics_rawdata_auth 4-statistics_rawdata_valid

* @param3  month_number导入的数据属于哪一期的 比如

* @param4  table_head用来判断excel表格是否有表头默认有

* @date : 2015/11/26

*/private function excelToTable($file,$tableid,$month_number,$table_head=1){if( !empty($file[ 'name' ] )){

$file_types = explode ( " . " , $file[ 'name' ] );

//判断是不是excel文件if ( !in_array(strtolower(end($file_types)) ,$excel_type)){

$this->show_msg( "不是Excel文件重新上传", "/search/patentStatistics/uploadRawdata") ;

}

//设置上传路径

$savePath = _WWW_ . 'www/tmp/' ;

//以时间来命名上传的文件

$str = date ( 'Ymdhis' );

$file_name = $str. " . " .end($file_types) ;

//是否上传成功

$tmp_file = $file[ 'tmp_name' ] ;if ( !copy($tmp_file,$savePath.$file_name)){

$this->show_msg( "上传失败" , "/search/patentStatistics/uploadRawdata" );

}if($tableid=="1" ){

//定义导入失败记录的文档

$logfile = $savePath.$str. ' .txt' ;

//读取excel存成数组该数组的key是从1开始

$res = $this->excelToArray($savePath.$file_name,end($file_types));

//echo ;exit;

//如果有表头则过滤掉第一行if($table_head)unset($res[1] );

//循环写入不一次性写入防止有错误的记录错误记录会记录下第一个字段到txt文档中去foreach($res as $k =>$v){foreach($fields as $key=>$val){

if($v[$key]===null){

$v[$key] = 'null' ;

}

$data[$val] = $v[$key] ;

}

//该字段比较特殊必须导入表中都有该字段

$data[ 'month_number' ] = $month_number;

$result = $rawdata_obj->addSave($data) ;unset($data);if( !$result){

$this ->logFile($logfile,$v[0] );

}

}if(file_get_contents($logfile))return $logfile;elsereturn true;

}

}

二、导出该功能支持页面上html中table表格直接导出

1、前端代码
