php - 如何打印mysql报告并导出到excel

标签 php mysql reporting export-to-excel database-replication

我有一个员工数据库，已将其复制到主/从数据库中，我想生成一份可打印并可导出到 Excel 的报告。我正在使用 xampp。这是我的代码:

<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Replication</title>
</head>
<body>
<?php
//connecting to the master server
$con = mysql_connect("localhost","justin","topdeveloper") or $con = false;
//if connection to the master server fails don\t connect to the slave
if ($con!=false) {
mysql_close($con);
//connecting to the slave server
$con = mysql_connect("localhost","root","") or die ("Could not connect to MySQL");

mysql_Select_db('clients',$con);
//the timestampdiff function gets the age of the person by subtracting the date_of_birth from the current date
$result=mysql_query("SELECT `first_name`,`second_name`,`last_name`,`id_number`,`phone_number`,`home_town`, TIMESTAMPDIFF(YEAR,date_of_birth,CURDATE()) AS `age` FROM `bio_data` ORDER BY age DESC");
     echo "<table border='1'>";
           echo "<tr align='center'>";  
            echo"<th><font color='black'>" ."First Name"."</font></th>";
            echo"<th><font color='black'>" ."Second Name"."</font></th>";
            echo"<th><font color='black'>" ."Last Name"."</font></th>";
            echo"<th><font color='black'>" ."Id Number"."</font></th>";
            echo"<th><font color='black'>" ."Phone Number"."</font></th>";
            echo"<th><font color='black'>" ."Home Town"."</font></th>";
            echo"<th><font color='black'>" ."Age"."</font></th>";
            echo "</tr>";   
while($row = mysql_fetch_array($result)){
            //echo "<table border='1'>";
            echo "<tr align='center' >";    
            echo"<td><font color='black'>" .$row['first_name']."</font></td>";
            echo"<td><font color='black'>" .$row['second_name']."</font></td>";
            echo"<td><font color='black'>". $row['last_name']. "</font></td>";
            echo"<td><font color='black'>". $row['id_number']. "</font></td>";
            echo"<td><font color='black'>". $row['phone_number']. "</font></td>";
            echo"<td><font color='black'>". $row['home_town']. "</font></td>";
            echo"<td><font color='black'>". $row['age']. "</font></td>";            
            echo "</tr>";   


}
    echo "</table>";
    mysql_close($con);

}

?>

最佳答案

我能够添加一个 Excel 类并编写一个函数来下载文件(工作正常)，但我有一个问题，当我加载主文件(index.php)时，文件会自动下载。以下是我的主要 php 文件。

index.php:

<!DOCTYPE html>
