ThinkPHP exports csv format documents

The export of csv format files here is similar to the export of excel. You can refer to the code to implement the export function.

/**
	 * csv导出
	 */
	public function exportVoter(){
 		header( "Cache-Control: public" );
		header( "Pragma: public" );
		header("Content-type:application/vnd.ms-excel");
		header("Content-Disposition:attachment;filename=投票人信息.csv");
		header('Content-Type:APPLICATION/OCTET-STREAM');
		ob_start();
		$header_str =  iconv("utf-8",'gbk',"姓名,性别,电话,密码\n"); 
		$voter = new \Admin\Model\VotersModel ();
		//$data = I ( 'get.' );print_r($data);exit();
		if (I ( 'get.name' )!="") {
			$name = I ( 'get.name' );
		} else {
			$name = "";
		}		
		$where=($name==''?'':" and v.name like '%{$name}%'");
		$list=$voter->query("select v.*,d.deptName from voters v inner join wkrj_auth_dept
				 d on v.deptid=d.id".$where);
		$file_str='';
		if($list){
			foreach ($list as $row){
				$file_str.= $row['name'].','.$row['sex'].','.$row['phone'].','.$row['password']."\n";
			}
		}else{
			echo "导出失败!";
		}
		//exit($file_str);
		//iconv转码函数
		$file_str=  iconv("utf-8",'gbk',$file_str);
			ob_end_clean();
			echo $header_str;
			echo $file_str;
	}

The above introduces ThinkPHP to export csv format documents, including the content. I hope it will be helpful to friends who are interested in PHP tutorials.
