php快速导出csv格式数据程序代码
导出csv数据很简单因为csv格式的数据就是一个文本类型了,我们要导入到只要以,号分开它们数据就可以了,然后再利用header输入csv格式或者excel格式就可以了.
csv文件格式,代码如下
$exportdata = '规则111,有效期'."\n";
csv文件在php输出需要使用header告诉浏览器格式,代码如下:
- header("Content-type:application/vnd.ms-excel");
- header("Content-Disposition: attachment; filename=$filename");
例子,代码如下:
- $exportdata = '规则111,规则222,审222,规222,服2222,规则1,规则2,规则3,匹配字符,设置时间,有效期'."\n";
- $date = date("YmdHis");
- if (!emptyempty($lists)){
- foreach($lists as $key => $value){
- $time = date("Y-m-d_H:i:s", $value['add_time']);
- $exportdata .= "\"\t".$value['Rule_id']."\",\"\t".$value['Rule_name']."\",\"\t".$value['Matching_level']."\",\"\t"."{$value['Rule_action']}"."\",\"\t".$value['Service_type']."\",\"\t".$value['Keyword1']."\",\"\t".$value['Keyword2']."\",\"\t".$value['Keyword3']."\",\"\t".$value['Matching_word']."\",\"\t".$value['Set_time']."\",\"\t".$value['Validation_time']."\"\n";
- }
- }
- $filename = "plcnetinfo_{$date}.csv";
- header("Content-type:application/vnd.ms-excel");
- header("Content-Disposition: attachment; filename=$filename");
- header("Expires: 0");
- header("Pragma: public");
- header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
- header("Cache-Control: public");
- echo(mb_convert_encoding($exportdata,"gb2312","UTF-8"));
下面再整理了一个php+mysql导入csv数据的例子,代码如下:
- export_csv();
- function export_csv() {
- $filename = date('YmdHis').".csv";
- header("Content-type:text/csv");
- header("Content-Disposition:attachment;filename=".$filename);
- header('Cache-Control:must-revalidate,post-check=0,pre-check=0');
- header('Expires:0');
- header('Pragma:public');
- echo array_to_string(get_export_data());
- }
- function array_to_string($result) {
- if(emptyempty($result)) {
- return i("没有符合您要求的数据!^_^");
- }
- $data = '书ID,书名'."\n";
- $size_result = sizeof($result);
- for($i = 0 ; $i < $size_result ; $i++) {
- $data .= i($result[$i]['name']).','.i($result[$i]['option'])."\n";
- }
- return $data;
- }
- function get_export_data() {
- $link = mysql_connect('localhost','root','121051xz') or die(mysql_error());
- mysql_select_db('ht');
- mysql_query("set names 'utf8'");
- $sql = 'select * from booklist';
- $result = mysql_query($sql);
- $rowaa = mysql_fetch_array($result);
- $res = array();
- $i = 0;
- while($row = mysql_fetch_array($result)) {
- $res[$i]['name'] = $row['bookid'];
- $res[$i]['option'] = $row['bookname'];
- $i++;
- }
- return $res;
- }
- function i($strInput) {
- return iconv('utf-8','gb2312',$strInput);
- }
