php - 将 MySQL DB 导出到 Excel(连接问题)

Question

我在 MySQL DB 中有一个表，我想将其导出到 Excel。我尝试了很多源代码，但似乎没有什么对我有用；看来我遇到了连接问题，它应该是在我的 .php 代码和数据库之间。

首先，我使用 XMPP 来托管我的数据库(phpmyadmin)，我可以通过输入 localhost/phpmyadmin 或 localhost:80/phpmyadmin 我创建的数据库来访问它，第一个称为“test”，第二个称为“gfdepot” .嗯，我对第二个感兴趣。在“gfdepot”数据库中，我有 6 个表，并且我对名为“zone”的表感兴趣。

嗯，目前我正在使用 eclipse IDE(安装了 .php 扩展)来编写我的网站脚本。我想要的只是有一个可单击的按钮将“区域”表导出到 Excel 文件。可点击的按钮工作正常，但“.php”页面不起作用! 无论我尝试什么，我总是收到连接错误。 目前，我正在尝试下面的代码。

<?php
/*******EDIT LINES 3-8*******/
$DB_Server = "localhost"; //MySQL Server    
$DB_Username = "root"; //MySQL Username     
$DB_Password = "";             //MySQL Password     
$DB_DBName = "gfdepot";         //MySQL Database Name  
$DB_TBLName = "zone"; //MySQL Table Name   
$filename = "excelfilename";         //File Name
/*******YOU DO NOT NEED TO EDIT ANYTHING BELOW THIS LINE*******/    
//create MySQL connection   
$sql = "Select * from $DB_TBLName";
$Connect = @mysql_connect($DB_Server, $DB_Username, $DB_Password) or die("Couldn't connect to MySQL:<br>" . mysql_error() . "<br>" . mysql_errno());
//select database   
$Db = @mysql_select_db($DB_DBName, $Connect) or die("Couldn't select database:<br>" . mysql_error(). "<br>" . mysql_errno());   
//execute query 
$result = @mysql_query($sql,$Connect) or die("Couldn't execute query:<br>" . mysql_error(). "<br>" . mysql_errno());    
$file_ending = "xls";
//header info for browser
header("Content-Type: application/xls");    
header("Content-Disposition: attachment; filename=$filename.xls");  
header("Pragma: no-cache"); 
header("Expires: 0");
/*******Start of Formatting for Excel*******/   
//define separator (defines columns in excel & tabs in word)
$sep = "\t"; //tabbed character
//start of printing column names as names of MySQL fields
for ($i = 0; $i < mysql_num_fields($result); $i++) {
echo mysql_field_name($result,$i) . "\t";
}
print("\n");    
//end of printing column names  
//start while loop to get data
    while($row = mysql_fetch_row($result))
    {
        $schema_insert = "";
        for($j=0; $j<mysql_num_fields($result);$j++)
        {
            if(!isset($row[$j]))
                $schema_insert .= "NULL".$sep;
            elseif ($row[$j] != "")
                $schema_insert .= "$row[$j]".$sep;
            else
                $schema_insert .= "".$sep;
        }
        $schema_insert = str_replace($sep."$", "", $schema_insert);
        $schema_insert = preg_replace("/\r\n|\n\r|\n|\r/", " ", $schema_insert);
        $schema_insert .= "\t";
        print(trim($schema_insert));
        print "\n";
    }   
?>

这就是我得到的。

" . mysql_error() . "
" . mysql_errno()); //select database $Db = @mysql_select_db($DB_DBName, $Connect) or die("Couldn't select database:
" . mysql_error(). "
" . mysql_errno()); //execute query $result = @mysql_query($sql,$Connect) or die("Couldn't execute query:
" . mysql_error(). "
" . mysql_errno()); $file_ending = "xls"; //header info for browser header("Content-Type: application/xls"); header("Content-Disposition: attachment; filename=$filename.xls"); header("Pragma: no-cache"); header("Expires: 0"); /*******Start of Formatting for Excel*******/ //define separator (defines columns in excel & tabs in word) $sep = "\t"; //tabbed character //start of printing column names as names of MySQL fields for ($i = 0; $i < mysql_num_fields($result); $i++) { echo mysql_field_name($result,$i) . "\t"; } print("\n"); //end of printing column names //start while loop to get data while($row = mysql_fetch_row($result)) { $schema_insert = ""; for($j=0; $j

这是我在这里发表的第一篇文章，我不是编程专家，这是我第一次尝试 .php 代码，并提前 tnx

切换主机名以指定端口号

例如。本地主机:3306
