使用PHP从mySQL到XLS？

如何使用PHP从mySQL表创建.XLS文档

我几乎什么都试过了，没有成功

基本上，我需要获取表单数据，并将其输入数据库（我已经完成了），然后我需要检索该表数据并将其解析为microsoft excel文件，该文件需要自动保存到web服务器上

    <?php

// DB TABLE Exporter
//
// How to use:
//
// Place this file in a safe place, edit the info just below here
// browse to the file, enjoy!

// CHANGE THIS STUFF FOR WHAT YOU NEED TO DO

     $dbhost  = "-";
     $dbuser  = "-";
     $dbpass  = "-";
     $dbname  = "-";
     $dbtable = "-";

// END CHANGING STUFF

$cdate = date("Y-m-d"); // get current date


// first thing that we are going to do is make some functions for writing out
// and excel file. These functions do some hex writing and to be honest I got 
// them from some where else but hey it works so I am not going to question it 
// just reuse


// This one makes the beginning of the xls file
function xlsBOF() {
    echo pack("ssssss", 0x809, 0x8, 0x0, 0x10, 0x0, 0x0);
    return;
}

// This one makes the end of the xls file
function xlsEOF() {
    echo pack("ss", 0x0A, 0x00);
    return;
}

// this will write text in the cell you specify
function xlsWriteLabel($Row, $Col, $Value ) {
    $L = strlen($Value);
    echo pack("ssssss", 0x204, 8 + $L, $Row, $Col, 0x0, $L);
    echo $Value;
    return;
}



// make the connection an DB query
$dbc = mysql_connect( $dbhost , $dbuser , $dbpass ) or die( mysql_error() );
mysql_select_db( $dbname );
$q = "SELECT * FROM ".$dbtable." WHERE date ='$cdate'";
$qr = mysql_query( $q ) or die( mysql_error() );

// start the file
xlsBOF();

// these will be used for keeping things in order.
$col = 0;
$row = 0;

// This tells us that we are on the first row
$first = true;

while( $qrow = mysql_fetch_assoc( $qr ) )
{
    // Ok we are on the first row
    // lets make some headers of sorts
    if( $first )
    {
        foreach( $qrow as $k => $v )
        {
            // take the key and make label
            // make it uppper case and replace _ with ' '
            xlsWriteLabel( $row, $col, strtoupper( ereg_replace( "_" , " " , $k ) ) );
            $col++;
        }

        // prepare for the first real data row
        $col = 0;
        $row++;
        $first = false;
    }

    // go through the data
    foreach( $qrow as $k => $v )
    {
        // write it out
        xlsWriteLabel( $row, $col, $v );
        $col++;
    }
    // reset col and goto next row
    $col = 0;
    $row++;
}

xlsEOF();
exit();
?>

我似乎不知道如何将fwrite集成到所有这些中，以便将生成的数据写入一个.xls文件中，我该怎么做呢

我需要得到这个工作相当紧迫，所以任何帮助将不胜感激。

Thanx guys.

如果您的数据库有某种前端（如phpMyAdmin或SQLyog），您可以将表（或任何SELECT查询的结果）导出到CSV并在Excel中打开

评论后编辑： 我曾经创建过一个XLS。这有点不同，但我所做的是将其放在PHP的顶部（在生成任何输出之前）：

在脚本的其余部分，我只是重复了一个表（table、tr、td…等等）

---

此脚本的执行将为用户提供下载。我认为Content disposition属性有一些不同的选项（可能有一个选项允许脚本保存文件）。

如果我没有弄错，您发布的脚本工作正常并创建了正确的xls文件，您只想保存输出，请参阅。使用ob_get_clean（），您可以获取创建的xls文件并将其写入服务器的某个位置

---

也许你还可以考虑其他选项，比如把你的数据保存到Excel中可以读取的其他格式（.CSV，它也可以读取一些HTML/XML表）。

我甚至不知道这些是否有意义，但我在xlsBOF、xlsEOF和xlsWriteLabel函数中添加了fwrite，以尝试将数据写入导出的.xls文件，它可以这样工作吗？

我在项目中经常使用PEAR，而且效果很好。不过，它会生成Excel 5.0级别的文件，因此，如果您需要更高级的文件，它可能不足以满足您的需要，但它会生成一个本机.xls，而不仅仅是一个伪装为.xls的.csv文件。

一切正常，答案就在这里。：-）

---

它需要自动化，脚本将每天在指定的时间通过cron作业运行，我只需要弄清楚如何让脚本自动将生成的xls数据保存到文件中。在cron中，您还可以运行wget将php脚本的输出保存到某个地方。我将尝试对Content-disposition属性进行一些研究，看看它是否也可以使用cron。有什么方法可以用fopen，fwrite fclose的方式来做吗？你可以试着打开一个XLS文件，写一个逗号分隔的值或者一个html表格，保存它，然后在Excel中打开它。看看会发生什么。这就是我现在试图做的，但我会试试看，看看会发生什么，这会让你们保持联系。：-）我用ob_get_clean（）尝试了它，但它不起作用，下面是我现在正在编写的代码：fopen&co.不应该在xlsEOF中吗？xlsWriteLabel是为每个单元格调用的。我试试看，thanx。我会向你通报进展情况。
