通过PHP从SQL生成Excel
我正在使用下面的代码来从sql生成excel通过php.this是一个modeifed verion的工作代码..
工作代码（无错误）

它显示以下错误

现在，您在尝试查询数据库后select数据库：
$numrow12 = mysql_query("SELECT * FROM mastertable WHERE pdfstatus = 1 ORDER BY tstamp DESC"); mysql_select_db("brainoidultrafb", $link);
这是行不通的。 只需交换订单，以便select数据库， 然后查询它：
mysql_select_db("brainoidultrafb", $link); $numrow12 = mysql_query("SELECT * FROM mastertable WHERE pdfstatus = 1 ORDER BY tstamp DESC");
至于你的第二个问题，你覆盖循环的每一个迭代$sheet1 。 做这个，而不是：
$sheet1 = array( array('StudentID','Students Email' ,'Diagnosis','TimeStamp' ,) ); while($row = mysql_fetch_array($numrow12)) { $sheet1[] = array($row['student_id'], $row['email_id'], $row['diagnosis'], $row['tstamp'],); }
对于你的第二个问题，使用： $sheet1[] =
将元素追加到$ sheet1数组中。 你在循环的每一次迭代之后都会replace它。
您可能需要在while循环之外初始化$sheet1以避免警告。 $sheet1 = array();
