php 自定义函数实现将数据 以excel 表格形式导出示例

本文实例讲述了php 自定义函数实现将数据 以excel 表格形式导出。分享给大家供大家参考，具体如下：

/**
* 导出数据为excel表格
* @param
* array $data  一个二维数组,结构如同从数据库查出来的数组
* array $title  excel的第一行标题,一个数组,如果为空则没有标题
* string $filename 下载的文件名
*/
function exportexcel($data=array(),$title=array(),$filename='report'){
    header("content-type:application/octet-stream");
    header("accept-ranges:bytes");
    header("content-type:application/vnd.ms-excel");
    header("content-disposition:attachment;filename=".$filename.".xls");
    header("pragma: no-cache");
    header("expires: 0");
    //导出xls 开始
    if (!empty($title)){
      foreach ($title as $k => $v) {
        $title[$k]=iconv("utf-8", "gb2312",$v);
      }
      $title= implode("\t", $title);
      echo "$title\n";
    }
    if (!empty($data)){
      foreach($data as $key=>$val){
        foreach ($val as $ck => $cv) {
          $data[$key][$ck]=mb_convert_encoding($cv,"gb2312","utf-8");
        }
        $data[$key]=implode("\t", $data[$key]);
      }
      echo implode("\n",$data);
    }
}

php内置函数讲解

string mb_convert_encoding( $str, $encoding1,$encoding2 )

$str，要转换编码的字符串
$encoding1，目标编码，如utf-8,gbk，大小写均可
$encoding2，原编码，如utf-8,gbk，大小写均可

demo

$title = array("title1","title2","title3");
$data = array("数据1","数据2","数据3");
$filename = "demo";
exportexcel($data,$title,$filename);
