利用php導出mysql數據庫為excel表格的方法很多,最簡單的就直接使用php fputcsv函數了,還有就是直接輸入csv格式也是可以了,要生成excel標準格式我們需使用第三方插件了.

方法一,利用fputcsv,代碼如下:

// 輸出Excel文件頭，可把user.csv換成你要的文件名

header('Content-Type: application/vnd.ms-excel');

header('Content-Disposition: attachment;filename="user.csv"');

header('Cache-Control: max-age=0');

// 從數據庫中獲取數據，為了節省內存，不要把數據一次性讀到內存，從句柄中一行一行讀即可

$sql = 'select * from tbl where ……';

$stmt = $db->query($sql);

// 打開PHP文件句柄，php://output 表示直接輸出到瀏覽器

$fp = fopen('php://output', 'a');

// 輸出Excel列名信息

$head = array('姓名', '性別', '年齡', 'Email', '電話', '……');

foreach ($head as $i => $v) {

// CSV的Excel支持GBK編碼，一定要轉換，否則亂碼

$head[$i] = iconv('utf-8', 'gbk', $v);

}

// 將數據通過fputcsv寫到文件句柄

fputcsv($fp, $head);

// 計數器

$cnt = 0;

// 每隔$limit行，刷新一下輸出buffer，不要太大，也不要太小

$limit = 100000;

// 逐行取出數據，不浪費內存

while ($row = $stmt->fetch(Zend_Db::FETCH_NUM)) {

//開源代碼Vevb.com

$cnt ++;

if ($limit == $cnt) { //刷新一下輸出buffer，防止由于數據過多造成問題

ob_flush();

flush();

$cnt = 0;

}

foreach ($row as $i => $v) {

$row[$i] = iconv('utf-8', 'gbk', $v);

}

fputcsv($fp, $row);

}

方法二,直接在瀏覽器用header輸出csv格式的數據,代碼如下:

<?php

/*連接數據庫*/

$DB_Server = "localhost";

$DB_Username = "root";

$DB_Password = "123456";

$DB_DBName = "mydb";  //目標數據庫名

$DB_TBLName = "mytable";  //目標表名

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

mysql_query("Set Names 'utf8'");

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

$file_type = "vnd.ms-excel";

$file_ending = "xls";

header("Content-Type: application/$file_type;charset=utf8");

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

//header("Pragma: no-cache");

/*寫入備注信息*/

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

$title = "數據庫名:$DB_DBName,數據表:$DB_TBLName,備份日期:$now_date";

echo("$titlen");

/*查詢數據庫*/

$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());

/*寫入表字段名*/

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

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

}

echo "n";

/*寫入表數據*/

$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; //處理NULL字段

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

    $data .= "$row[$i]".$sep;

   else

    $data .= "".$sep; //處理空字段

  }

echo $data."n";

}

?>

例3,第二個差不多了,代碼如下:

//搜索

    $start_time = strtotime($start_date);

    $end_time = strtotime($end_date);

    $sql = "select a.*,b.order_amount,b.money_paid from ".$ecs->table('invoice')." as a ".

                " left join ".$ecs->table('order_info')." as b on a.order_id=b.order_sn".

                " where a.add_time >=".$start_time." and a.add_time <=".$end_time." ";

    $temp_list = $db->getAll($sql);

    if($temp_list){//有數據

        $Html.='<table width="700" border="1" align="center" cellpadding="2" cellspacing="1">
