在 PHP 中将 MySQL 数据导出到 Excel

Question

我正在尝试将我的 MySQL 数据导入 Excel 文件，但我遇到了 Excel 单元格的问题。我所有的文本都放在一个单元格中，我希望将每一行的值放在单独的 Excel 单元格中。这是我的代码：

$queryexport = ("
SELECT username,password,fullname FROM ecustomer_users
WHERE fk_customer='".$fk_customer."'
");

$row = mysql_fetch_assoc($queryexport);

$result = mysql_query($queryexport);
$header = '';

for ($i = 0; $i < $count; $i++){
   $header .= mysql_field_name($result, $i)."\t";
   }

while($row = mysql_fetch_row($result)){
   $line = '';
   foreach($row as $value){
          if(!isset($value) || $value == ""){
                 $value = "\t";
          }else{
                 $value = str_replace('"', '""', $value);
                 $value = '"' . $value . '"' . "\t";
                 }
          $line .= $value;
          }
   $data .= trim($line)."\n";
   $data = str_replace("\r", "", $data);

if ($data == "") {
   $data = "\nno matching records found\n";
   }
}
header("Content-type: application/vnd.ms-excel; name='excel'");
header("Content-Disposition: attachment; filename=exportfile.xls");
header("Pragma: no-cache");
header("Expires: 0");

// output data
echo $header."\n".$data;

mysql_close($conn);`

Answer 1

只需尝试以下方法：

PHP部分：

<?php
/*******EDIT LINES 3-8*******/
$DB_Server = "localhost"; //MySQL Server    
$DB_Username = "username"; //MySQL Username     
$DB_Password = "password";             //MySQL Password     
$DB_DBName = "databasename";         //MySQL Database Name  
$DB_TBLName = "tablename"; //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";
    }   
?>

我认为这可以帮助您解决问题。

试试这个代码。它绝对有效。

<?php
// Connection 

$conn=mysql_connect('localhost','root','');
$db=mysql_select_db('excel',$conn);

$filename = "Webinfopen.xls"; // File Name
// Download file
header("Content-Disposition: attachment; filename=\"$filename\"");
header("Content-Type: application/vnd.ms-excel");
$user_query = mysql_query('select name,work from info');
// Write data to file
$flag = false;
while ($row = mysql_fetch_assoc($user_query)) {
    if (!$flag) {
        // display field/column names as first row
        echo implode("\t", array_keys($row)) . "\r\n";
        $flag = true;
    }
    echo implode("\t", array_values($row)) . "\r\n";
}
?>

如果您只想将查询数据转储到 excel 中，我必须经常这样做，并且使用 html 表是一种非常简单的方法。我使用 mysqli 进行数据库查询，并使用以下代码导出到 excel：

header("Content-Type: application/xls");    
header("Content-Disposition: attachment; filename=filename.xls");  
header("Pragma: no-cache"); 
header("Expires: 0");


echo '<table border="1">';
//make the column headers what you want in whatever order you want
echo '<tr><th>Field Name 1</th><th>Field Name 2</th><th>Field Name 3</th></tr>';
//loop the query data to the table in same order as the headers
while ($row = mysqli_fetch_assoc($result)){
    echo "<tr><td>".$row['field1']."</td><td>".$row['field2']."</td><td>".$row['field3']."</td></tr>";
}
echo '</table>';

Answer 5

这是新版本的php代码

$servername = "localhost";
$username = "root";
$password = "";
$dbname = "your_dbname";
//mysql and db connection

$con = new mysqli($servername, $username, $password, $dbname);

if ($con->connect_error) {  //error check
    die("Connection failed: " . $con->connect_error);
}
else
{

}


$DB_TBLName = "your_table_name"; 
$filename = "excelfilename";  //your_file_name
$file_ending = "xls";   //file_extention

header("Content-Type: application/xls");    
header("Content-Disposition: attachment; filename=$filename.'.'.$file_ending");  
header("Pragma: no-cache"); 
header("Expires: 0");

$sep = "\t";

$sql="SELECT * FROM $DB_TBLName"; 
$resultt = $con->query($sql);
while ($property = mysqli_fetch_field($resultt)) { //fetch table field name
    echo $property->name."\t";
}

print("\n");    

while($row = mysqli_fetch_row($resultt))  //fetch_table_data
{
    $schema_insert = "";
    for($j=0; $j< mysqli_num_fields($resultt);$j++)
    {
        if(!isset($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";
}

试试这个代码：

<?php
    header("Content-type: application/vnd-ms-excel");

    header("Content-Disposition: attachment; filename=hasil-export.xls");

    include 'view-lap.php';
?>

Answer 8

试试这个代码

数据.php

    <table border="1">
<tr>
    <th>NO.</th>
    <th>NAME</th>
    <th>Major</th>
</tr>
<?php
//connection to mysql
mysql_connect("localhost", "root", ""); //server , username , password
mysql_select_db("codelution");

//query get data
$sql = mysql_query("SELECT * FROM student ORDER BY id ASC");
$no = 1;
while($data = mysql_fetch_assoc($sql)){
    echo '
    <tr>
        <td>'.$no.'</td>
        <td>'.$data['name'].'</td>
        <td>'.$data['major'].'</td>
    </tr>
    ';
    $no++;
}
?>

excel文件代码

export.php

<?php
// The function header by sending raw excel
header("Content-type: application/vnd-ms-excel");
// Defines the name of the export file "codelution-export.xls"
header("Content-Disposition: attachment; filename=codelution-export.xls");
// Add data table
include 'data.php';
?>

如果是mysqli版本

$sql="SELECT * FROM user_details";
$result=mysqli_query($conn,$sql);
if(mysqli_num_rows($result) > 0)
{
    $no = 1;
            while($data = mysqli_fetch_assoc($result))
            {echo '
    <tr>
        <<td>'.$no.'</td>
        <td>'.$data['name'].'</td>
        <td>'.$data['major'].'</td>

    </tr>
    ';
    $no++;

Answer 9

您可以使用这个简单的代码将数据从 MySQL 导出到 Excel。

<?php
include('db_con.php');


$stmt=$db_con->prepare('select * from books');
$stmt->execute();


$columnHeader ='';
$columnHeader = "Sr NO"."\t"."Book Name"."\t"."Book Author"."\t"."Book 
ISBN"."\t";


$setData='';

while($rec =$stmt->FETCH(PDO::FETCH_ASSOC))
{
 $rowData = '';
 foreach($rec as $value)
 {
  $value = '"' . $value . '"' . "\t";
  $rowData .= $value;
 }
 $setData .= trim($rowData)."\n";
}


header("Content-type: application/octet-stream");
header("Content-Disposition: attachment; filename=Book record 
sheet.xls");
header("Pragma: no-cache");
header("Expires: 0");

echo ucwords($columnHeader)."\n".$setData."\n";

?>

Answer 10

John Peter 和 Dileep kurahe 的帖子帮助我开发了我认为更简单、更清洁的解决方案，以防万一其他人仍在寻找。 （我没有显示任何数据库代码，因为我实际上使用了 $_SESSION 变量。）

上述解决方案在加载到 Excel 时总是会导致错误，即扩展名与格式类型不匹配。其中一些解决方案创建了一个电子表格，其中包含跨页面的列中的数据，其中具有列标题并将数据列在行中更为传统。所以这是我的简单解决方案：

$filename = "webreport.csv";
header("Content-Type: application/xls");    
header("Content-Disposition: attachment; filename=$filename");  
header("Pragma: no-cache"); 
header("Expires: 0");
foreach($results as $x => $x_value){
    echo '"'.$x.'",' . '"'.$x_value.'"' . "\r\n";
}

1. 更改为 .csv（Excel 会立即更新为 .xls，加载时没有错误。）
2. 使用逗号作为分隔符。
3. 双引号键和值以转义数据中的任何逗号。
4. 我还在 $results 前面添加了列标题，这样电子表格看起来更漂亮。

Answer 11

请尝试以下代码。 只更新两个值。
1.your_database_name 2.table_name

 <?php
    $host="localhost";
    $username="root";
    $password="";
    $dbname="your_database_name";
    $con = new mysqli($host, $username, $password,$dbname); 

        $sql_data="select * from table_name";
        $result_data=$con->query($sql_data);
        $results=array();
    filename = "Webinfopen.xls"; // File Name
    // Download file
    header("Content-Disposition: attachment; filename=\"$filename\"");
    header("Content-Type: application/vnd.ms-excel");

    $flag = false;
    while ($row = mysqli_fetch_assoc($result_data)) {
        if (!$flag) {
            // display field/column names as first row
            echo implode("\t", array_keys($row)) . "\r\n";
            $flag = true;
        }
        echo implode("\t", array_values($row)) . "\r\n";
    }
    ?>

Answer 12

这是基于约翰彼得上面的回答。该代码运行良好，但我需要它用于 WordPress。所以，我做了这样的事情：

<?php

require '../../../wp-load.php';

$file_name = "registered-users";
$args = array( 'role' => 'client',
   'meta_query' => array( array(
       'key' => '_dt_transaction_archived',
       'compare' => 'NOT EXISTS'
   ) ),
   'order' => 'DESC',
   'orderby' => 'ID'
);
$users = get_users( $args );
$file_ending = "xls";

// Header info for browser
header( "Content-Type: application/xls" );
header( "Content-Disposition: attachment; filename=$file_name.$file_ending" );
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

print( "First Name" . $sep );
print( "Last Name" . $sep );
print( "E-Mail" . $sep );
print( "\n" );
// end of printing column names

// start foreach loop to get data
$schema_insert = "";

foreach ($users as $user) {
    if ( $user ) {
        $schema_insert = "$user->first_name" . $sep;
        $schema_insert .= "$user->last_name" . $sep;
        $schema_insert .= "$user->user_email" . $sep;
        print "\n";
        $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 ) );
    }
}
