我现在正在尝试将数据从数据库导出到 Excel 文件。但是，当我打开 Excel 文件时，数据全部在一列中。我想在一列中获取 MySql 数据库中一行的所有内容。例如，所有用户名应在一列中，所有名字应在一列中，依此类推
PHP 代码:
<?php
//include database configuration file
include ('connection.php');
//get records from database
$sql = ("SELECT * FROM employee ORDER BY username DESC");
if($result = mysqli_query($conn, $sql)){
if(mysqli_num_rows($result) > 0){
$delimiter = ",";
$filename = "members_" . date('Y-m-d') . ".csv";
//create a file pointer
$f = fopen('php://memory', 'w');
//set column headers
$field1 = "username";
$field2 = "firstname";
$field3 = "lastname";
$field4 = "phonenumber";
$field5 = "password";
$fields = array($field1 . $field2 . $field3 . $field4 . $field5);
fputcsv($f, $fields, $delimiter);
//output each row of the data, format line as csv and write to file pointer
while($row = mysqli_fetch_array($result)){
$lineData = array($row['username'], $row['firstname'], $row['lastname'], $row['phonenumber'], $row['password']);
fputcsv($f, $lineData, $delimiter);
}
//move back to beginning of file
fseek($f, 0);
//set headers to download file rather than displayed
header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename="' . $filename . '";');
//output all remaining data on a file pointer
fpassthru($f);
}
}
exit;
?>
我的html代码:
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>
<div class="container">
<div class="panel panel-default">
<div class="panel-heading">

<a href="exportData.php" class="btn btn-success pull-right">Export Members</a>
</div>
<div class="panel-body">
<table class="table table-bordered">

<tr>

<th>Email</th>
<th>Phone</th>
<th>Created</th>
<th>Status</th>
</tr>
</thead>
<tbody>
<?php
//include database configuration file
include 'connection.php';
//get records from database
$sql = ("SELECT * FROM employee ORDER BY username DESC");
if($sql->num_rows > 0){
if(mysqli_num_rows($result) > 0){ ?>
<tr>
<td><?php echo $row['name']; ?></td>
<td><?php echo $row['email']; ?></td>
<td><?php echo $row['phone']; ?></td>
<td><?php echo $row['created']; ?></td>
<td><?php echo ($row['status'] == '1')?'Active':'Inactive'; ?></td>
</tr>
<?php } }else{ ?>
<tr><td colspan="5">No member(s) found.....</td></tr>
<?php } ?>

过去两个小时我一直在谷歌上搜索，但找不到解决方案。您知道一些工具或语言或解决此问题的方法吗？

最佳答案
在通用 HTML 表格中显示数据，然后转换并下载 Excel 文件
var xport = {
_fallbacktoCSV: true,
toXLS: function(tableId, filename) {
this._filename = (typeof filename == 'undefined') ? tableId : filename;
//var ieVersion = this._getMsieVersion();
//Fallback to CSV for IE & Edge
if ((this._getMsieVersion() || this._isFirefox()) && this._fallbacktoCSV) {
return this.toCSV(tableId);
} else if (this._getMsieVersion() || this._isFirefox()) {
alert("Not supported browser");
}
//Other Browser can download xls
var htmltable = document.getElementById(tableId);
var html = htmltable.outerHTML;
this._downloadAnchor("data:application/vnd.ms-excel" + encodeURIComponent(html), 'xls');
},
toCSV: function(tableId, filename) {
this._filename = (typeof filename === 'undefined') ? tableId : filename;
// Generate our CSV string from out HTML Table
var csv = this._tableToCSV(document.getElementById(tableId));
// Create a CSV Blob
var blob = new Blob([csv], { type: "text/csv" });
// Determine which approach to take for the download
if (navigator.msSaveOrOpenBlob) {
// Works for Internet Explorer and Microsoft Edge
navigator.msSaveOrOpenBlob(blob, this._filename + ".csv");
} else {
this._downloadAnchor(URL.createObjectURL(blob), 'csv');
}
},
_getMsieVersion: function() {
var ua = window.navigator.userAgent;
var msie = ua.indexOf("MSIE ");
if (msie > 0) {
// IE 10 or older => return version number
return parseInt(ua.substring(msie + 5, ua.indexOf(".", msie)), 10);
}
var trident = ua.indexOf("Trident/");
if (trident > 0) {
// IE 11 => return version number
var rv = ua.indexOf("rv:");
return parseInt(ua.substring(rv + 3, ua.indexOf(".", rv)), 10);
}
var edge = ua.indexOf("Edge/");
if (edge > 0) {
// Edge (IE 12+) => return version number
return parseInt(ua.substring(edge + 5, ua.indexOf(".", edge)), 10);
}
// other browser
return false;
},
_isFirefox: function(){
if (navigator.userAgent.indexOf("Firefox") > 0) {
return 1;
}
return 0;
},
_downloadAnchor: function(content, ext) {
var anchor = document.createElement("a");
anchor.style = "display:none !important";
anchor.id = "downloadanchor";
document.body.appendChild(anchor);
// If the [download] attribute is supported, try to use it
if ("download" in anchor) {
anchor.download = this._filename + "." + ext;
}
anchor.href = content;
anchor.click();
anchor.remove();
},
_tableToCSV: function(table) {
// We'll be co-opting `slice` to create arrays
var slice = Array.prototype.slice;
return slice
.call(table.rows)
.map(function(row) {
return slice
.call(row.cells)
.map(function(cell) {
return '"t"'.replace("t", cell.textContent);
})
.join(",");
})
.join("\r\n");
}
