我在MySQL数据库中有数据。我向用户发送一个URL，以获取他们的数据作为CSV文件。
我有链接的电子邮件，MySQL查询等覆盖。
当他们点击链接时，如何弹出从MySQL下载带有记录的CVS的窗口?
我已经有了所有能拿到唱片的资料。我只是不明白如何让PHP创建CSV文件，并让他们下载一个扩展名为. CSV的文件。
要让它以CSV格式发送，并给出文件名，请使用header():
http://us2.php.net/header
header('Content-type: text/csv');
header('Content-disposition: attachment; filename="myfile.csv"');
至于创建CSV本身，您只需要遍历结果集，格式化输出并发送它，就像处理任何其他内容一样。
Try:
header("Content-type: text/csv");
header("Content-Disposition: attachment; filename=file.csv");
header("Pragma: no-cache");
header("Expires: 0");
echo "record1,record2,record3\n";
die;
etc
编辑:这是我用来可选地编码CSV字段的代码片段:
function maybeEncodeCSVField($string) {
if(strpos($string, ',') !== false || strpos($string, '"') !== false || strpos($string, "\n") !== false) {
$string = '"' . str_replace('"', '""', $string) . '"';
}
return $string;
}
创建您的文件，然后用正确的标题返回对它的引用，以触发另存为-根据需要编辑以下内容。将您的CSV数据放入$csvdata。
$fname = 'myCSV.csv';
$fp = fopen($fname,'wb');
fwrite($fp,$csvdata);
fclose($fp);
header('Content-type: application/csv');
header("Content-Disposition: inline; filename=".$fname);
readfile($fname);
<?
// Connect to database
$result = mysql_query("select id
from tablename
where shid=3");
list($DBshid) = mysql_fetch_row($result);
/***********************************
Write date to CSV file
***********************************/
$_file = 'show.csv';
$_fp = @fopen( $_file, 'wb' );
$result = mysql_query("select name,compname,job_title,email_add,phone,url from UserTables where id=3");
while (list( $Username, $Useremail_add, $Userphone, $Userurl) = mysql_fetch_row($result))
{
$_csv_data = $Username.','.$Useremail_add.','.$Userphone.','.$Userurl . "\n";
@fwrite( $_fp, $_csv_data);
}
@fclose( $_fp );
?>
首先将data作为String，以逗号作为分隔符(用“，”分隔)。就像这样
$CSV_string="No,Date,Email,Sender Name,Sender Email \n"; //making string, So "\n" is used for newLine
$rand = rand(1,50); //Make a random int number between 1 to 50.
$file ="export/export".$rand.".csv"; //For avoiding cache in the client and on the server
//side it is recommended that the file name be different.
file_put_contents($file,$CSV_string);
/* Or try this code if $CSV_string is an array
fh =fopen($file, 'w');
fputcsv($fh , $CSV_string , "," , "\n" ); // "," is delimiter // "\n" is new line.
fclose($fh);
*/
〇简单的方法
$data = array (
'aaa,bbb,ccc,dddd',
'123,456,789',
'"aaa","bbb"');
$fp = fopen('data.csv', 'wb');
foreach($data as $line){
$val = explode(",",$line);
fputcsv($fp, $val);
}
fclose($fp);
因此$data数组的每一行都将转到新创建的CSV文件的新行。它只适用于PHP 5及以后的版本。
而不是:
$query = "SELECT * FROM customers WHERE created>='{$start} 00:00:00' AND created<='{$end} 23:59:59' ORDER BY id";
$select_c = mysql_query($query) or die(mysql_error());
while ($row = mysql_fetch_array($select_c, MYSQL_ASSOC))
{
$result.="{$row['email']},";
$result.="\n";
echo $result;
}
Use:
$query = "SELECT * FROM customers WHERE created>='{$start} 00:00:00' AND created<='{$end} 23:59:59' ORDER BY id";
$select_c = mysql_query($query) or die(mysql_error());
while ($row = mysql_fetch_array($select_c, MYSQL_ASSOC))
{
echo implode(",", $row)."\n";
}
在$output变量中放入CSV数据，并返回正确的报头
header("Content-type: application/download\r\n");
header("Content-disposition: filename=filename.csv\r\n\r\n");
header("Content-Transfer-Encoding: ASCII\r\n");
header("Content-length: ".strlen($output)."\r\n");
echo $output;
header("Content-Type: text/csv");
header("Content-Disposition: attachment; filename=file.csv");
function outputCSV($data) {
$output = fopen("php://output", "wb");
foreach ($data as $row)
fputcsv($output, $row); // here you can change delimiter/enclosure
fclose($output);
}
outputCSV(array(
array("name 1", "age 1", "city 1"),
array("name 2", "age 2", "city 2"),
array("name 3", "age 3", "city 3")
));
php: / /输出 函数
最简单的方法是使用一个专门的CSV类，像这样:
$csv = new csv();
$csv->load_data(array(
array('name'=>'John', 'age'=>35),
array('name'=>'Adrian', 'age'=>23),
array('name'=>'William', 'age'=>57)
));
$csv->send_file('age.csv');
我知道这个帖子有点老了，但作为将来的参考，以及像我这样的新手:
这里的其他人都解释了如何创建CSV，但忽略了问题的基本部分:如何链接。为了链接到CSV-file的下载，只需链接到.php-file，该文件将响应为. CSV-file。PHP头文件可以做到这一点。这可以实现一些很酷的东西，比如向查询字符串中添加变量并自定义输出:
<a href="my_csv_creator.php?user=23&othervariable=true">Get CSV</a>
my_csv_creator.php可以使用查询字符串中给出的变量，例如使用不同的或自定义的数据库查询，更改CSV的列，个性化文件名等，例如:
User_John_Doe_10_Dec_11.csv
下面是@Andrew发布的php.net函数的改进版本。
function download_csv_results($results, $name = NULL)
{
if( ! $name)
{
$name = md5(uniqid() . microtime(TRUE) . mt_rand()). '.csv';
}
header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename='. $name);
header('Pragma: no-cache');
header("Expires: 0");
$outstream = fopen("php://output", "wb");
foreach($results as $result)
{
fputcsv($outstream, $result);
}
fclose($outstream);
}
它真的很容易使用，并且与MySQL(i)/PDO结果集一起工作。
download_csv_results($results, 'your_name_here.csv');
如果完成了页面，请记住在调用此函数后退出()。
如何写在CSV文件使用PHP脚本?其实我也在找这个。这在PHP中很简单。 Fputs(处理程序，内容)-这个函数为我有效地工作。首先，您需要使用fopen($CSVFileName， ' wb ')打开需要写入内容的文件。
$CSVFileName = “test.csv”;
$fp = fopen($CSVFileName, ‘wb’);
//Multiple iterations to append the data using function fputs()
foreach ($csv_post as $temp)
{
$line = “”;
$line .= “Content 1″ . $comma . “$temp” . $comma . “Content 2″ . $comma . “16/10/2012″.$comma;
$line .= “\n”;
fputs($fp, $line);
}
已经很好的解决了。我只是把全部代码放进去，这样新手就能得到全部帮助
<?php
extract($_GET); //you can send some parameter by query variable. I have sent table name in *table* variable
header("Content-type: text/csv");
header("Content-Disposition: attachment; filename=$table.csv");
header("Pragma: no-cache");
header("Expires: 0");
require_once("includes/functions.php"); //necessary mysql connection functions here
//first of all I'll get the column name to put title of csv file.
$query = "SHOW columns FROM $table";
$headers = mysql_query($query) or die(mysql_error());
$csv_head = array();
while ($row = mysql_fetch_array($headers, MYSQL_ASSOC))
{
$csv_head[] = $row['Field'];
}
echo implode(",", $csv_head)."\n";
//now I'll bring the data.
$query = "SELECT * FROM $table";
$select_c = mysql_query($query) or die(mysql_error());
while ($row = mysql_fetch_array($select_c, MYSQL_ASSOC))
{
foreach ($row as $key => $value) {
//there may be separator (here I have used comma) inside data. So need to put double quote around such data.
if(strpos($value, ',') !== false || strpos($value, '"') !== false || strpos($value, "\n") !== false) {
$row[$key] = '"' . str_replace('"', '""', $value) . '"';
}
}
echo implode(",", $row)."\n";
}
?>
我已将此代码保存在csv-download.php中
现在看看我是如何使用这些数据来下载csv文件的
<a href="csv-download.php?table=tbl_vfm"><img title="Download as Excel" src="images/Excel-logo.gif" alt="Download as Excel" /><a/>
因此，当我点击链接，它下载文件，而不带我到浏览器上的csv-download.php页面。
嘿它工作得很好....!!!!谢谢Peter Mortensen和Connor Burton
<?php
header("Content-type: application/csv");
header("Content-Disposition: attachment; filename=file.csv");
header("Pragma: no-cache");
header("Expires: 0");
ini_set('display_errors',1);
$private=1;
error_reporting(E_ALL ^ E_NOTICE);
mysql_connect("localhost", "user", "pass") or die(mysql_error());
mysql_select_db("db") or die(mysql_error());
$start = $_GET["start"];
$end = $_GET["end"];
$query = "SELECT * FROM customers WHERE created>='{$start} 00:00:00' AND created<='{$end} 23:59:59' ORDER BY id";
$select_c = mysql_query($query) or die(mysql_error());
while ($row = mysql_fetch_array($select_c, MYSQL_ASSOC))
{
$result.="{$row['email']},";
$result.="\n";
echo $result;
}
?>
除了上述内容，你可能还需要补充:
header("Content-Transfer-Encoding: UTF-8");
它在处理包含多种语言的文件时非常有用，比如人名或城市。
下面是一个使用PDO并包含列标题的完整工作示例:
$query = $pdo->prepare('SELECT * FROM test WHERE id=?');
$query->execute(array($id));
$results = $query->fetchAll(PDO::FETCH_ASSOC);
download_csv_results($results, 'test.csv');
exit();
function download_csv_results($results, $name)
{
header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename='. $name);
header('Pragma: no-cache');
header("Expires: 0");
$outstream = fopen("php://output", "wb");
fputcsv($outstream, array_keys($results[0]));
foreach($results as $result)
{
fputcsv($outstream, $result);
}
fclose($outstream);
}
您可以使用fputcsv函数简单地将数据写入CSV。让我们看看下面的例子。将列表数组写入CSV文件
$list[] = array("Cars", "Planes", "Ships");
$list[] = array("Car's2", "Planes2", "Ships2");
//define headers for CSV
header('Content-Type: text/csv; charset=utf-8');
header('Content-Disposition: attachment; filename=file_name.csv');
//write data into CSV
$fp = fopen('php://output', 'wb');
//convert data to UTF-8
fprintf($fp, chr(0xEF).chr(0xBB).chr(0xBF));
foreach ($list as $line) {
fputcsv($fp, $line);
}
fclose($fp);
编写自己的CSV代码可能是浪费你的时间，只是使用一个包，如league/ CSV -它为你处理所有困难的事情，文档是很好的，它是非常稳定/可靠的:

你需要使用作曲家。如果你不知道什么是作曲家，我强烈建议你去看看:https://getcomposer.org/
