PHP导出Mysql数据到Excel

临时需要将Mysql中一张表导出成Excel表格，有个phpexcel的插件可以用，我觉得有点麻烦，况且我是临时要备份的，就直接自己写了。

<?php 

/*连接数据库*/

 $DB_Server = "ServerIP";

 $DB_Username = "UserName"; 

 $DB_Password = "PassWord"; 

 $DB_DBName = "DBname";  //目标数据库名

$DB_TBLName = "TableName";  //目标表名



$Connect = @mysql_connect($DB_Server, $DB_Username, $DB_Password) or die("Couldn't connect."); 

 mysql_query("set names utf8"); 



$savename = date("YmjHis"); //导出excel文件名

$file_type = "vnd.ms-excel"; 

 $file_ending = "xls"; 

 header("Content-Type: application/$file_type;charset=utf-8"); 

 header("Content-Disposition: attachment; filename=".$savename.".$file_ending"); 

header("Pragma: no-cache"); 



/*写入备注信息*/

 $now_date = date("Y-m-j H:i:s"); 

 $title = "数据库名:$DB_DBName,数据表:$DB_TBLName,备份日期:$now_date"; 

 echo iconv("utf-8","gbk",$title)."\n"; 



/*查询数据库*/

 $sql = "Select * from $DB_TBLName"; 

 $ALT_Db = @mysql_select_db($DB_DBName, $Connect) or die("Couldn't select database"); 

 $result = @mysql_query($sql,$Connect) or die(mysql_error()); 



/*写入表字段名*/

for ($i = 0; $i < mysql_num_fields($result); $i++) { 

  

  echo mysql_field_name($result,$i) . "\t"; 

 } 

 echo "\n";



/*写入表数据*/

 $sep = "\t"; 

 while($row = mysql_fetch_row($result)) { 

  $data = ""; 

   for($i=0; $i<mysql_num_fields($result);$i++) { 

    if(!isset($row[$i])) 

     $data .= "NULL".$sep; //处理NULL字段

   elseif ($row[$i] != ""){

     $datmp=iconv("utf-8", "gbk",$row[$i]);

     $data .= $datmp.$sep; 

   }

    else 

     $data .= "".$sep; //处理空字段

  } 

  echo $data."\n"; 

 }

 ?> 

好了，这样直接访问这个php文件就可以将指定的表中数据导出了。
