将逗号作为分隔符导出到php中的CSV文件中 [英] put comma as separator in export to CSV in php
问题描述
单击下载按钮后，我必须以CSV文件的形式获取mysql数据.以下代码成功导出了数据，但添加了空格作为分隔符.但是我需要逗号分隔而不是空格，因为mysql数据以及csv文件的静态标头中都有空格.
HTML代码在下面.
<form name="downloadform" id="downloadform" action="exportcsv.php" method="POST">
<div style="font-weight:bold; line-height:30px;" class="TableContainer">
<label>Download CSV Format:</label>
<button class="blue" name="btnDwld" id="btnDwld" type="submit">Download</button>
</div>
</form>
并在下面导出到csv代码.
<?php
require_once 'dbconfig.php';
if(isset($_POST['btnDwld']))
{
$filname = "UploadRateWeight-".date("d-M-Y-H:i:s");
header("Content-type: text/csv");
header("Content-Disposition: attachment; filename=$filname.csv");
header("Pragma: no-cache");
function echocsv($fields)
{
$separator = ',';
foreach ($fields as $field) {
if (preg_match('/\\r|\\n|,|"/', $field)) {
$field = '"' . str_replace('"', '""', $field) . '"';
} // end if
echo $field.$separator;
} // end foreach
echo "\r\n";
}
$content = '';
$title = '';
$title = array('0'=>'head part1','1'=>'head part2','2'=>'head part3','3'=>'head part4','4'=>'head part5');
$headerr = echocsv($title);
$sql = "SELECT * FROM table_name";
$query = mysql_query($sql);
while($rs = mysql_fetch_array($query)) {
$name = $rs["name"];
$line = array('0'=>$name,'1'=>'','2'=>'','3'=>'','4'=>'');
echocsv($line);
//$content .= "\n";
}
}
.CSV文件中的输出如下所示.
head
----------
name1
name2
name3
如您所见，我将第一个列名命名为"head part1"，但它将像"head"一样显示为空格.
因此第二列名称采用了该名称.
part1,head
----------
和第三列名称使用此名称.
part2,head
----------
，依此类推.那么在php中导出CSV文件时如何使用逗号分隔?
请勿手动编写csv文件.使用内置功能.</p>
例如 http://uk3.php.net/manual/en/function.fputcsv.php
<?php
$delimiter = ',';
$enclosure = '"';
$list = array (
array('aaa', 'bbb', 'ccc', 'dddd'),
array('123', '456', '789'),
array('"aaa"', '"bbb"')
);
$fp = fopen('file.csv', 'w');
foreach ($list as $fields) {
fputcsv($fp, $fields, $delimiter, $enclosure);
}
fclose($fp);
?>
上面的代码将创建一个名为file.csv的文件，其中包含您的数据.然后，如果您想将此文件作为CSV文件发送给用户，则可以执行以下操作:
<?php
// Send the generated csv file to the browser as a download
header("Content-type: text/csv");
header("Content-Disposition: attachment; filename=file.csv");
header("Pragma: no-cache");
header("Expires: 0");
readfile('file.csv');
?>
或者，您可以发送CSV文件直接下载，而无需在服务器上创建文件，如下所示:
<?php
// mini-config
$delimiter = ',';
// Your data
$list = array (
array('aaa', 'bbb', 'ccc', 'dddd'),
array('123', '456', '789'),
array('"aaa"', '"bbb"')
);
// Send headers
header("Content-type: text/csv");
header("Content-Disposition: attachment; filename=file.csv");
header("Pragma: no-cache");
header("Expires: 0");
// Output csv data
foreach ($list as $row) {
echo implode($delimiter, $row) . "\r\n";
}
?>
希望这会有所帮助.
I have to get mysql data in a CSV file on click of download button. The below code exports data successfully but adds space as separator. But I need comma to be separator not space, As there are space in mysql data and also on static header of csv file.
HTML code is below.
<form name="downloadform" id="downloadform" action="exportcsv.php" method="POST">
<div style="font-weight:bold; line-height:30px;" class="TableContainer">
<label>Download CSV Format:</label>
<button class="blue" name="btnDwld" id="btnDwld" type="submit">Download</button>
</div>
</form>
And export to csv code is below.
<?php
require_once 'dbconfig.php';
if(isset($_POST['btnDwld']))
{
$filname = "UploadRateWeight-".date("d-M-Y-H:i:s");
header("Content-type: text/csv");
header("Content-Disposition: attachment; filename=$filname.csv");
header("Pragma: no-cache");
function echocsv($fields)
{
$separator = ',';
foreach ($fields as $field) {
if (preg_match('/\\r|\\n|,|"/', $field)) {
$field = '"' . str_replace('"', '""', $field) . '"';
} // end if
echo $field.$separator;
} // end foreach
echo "\r\n";
}
$content = '';
$title = '';
$title = array('0'=>'head part1','1'=>'head part2','2'=>'head part3','3'=>'head part4','4'=>'head part5');
$headerr = echocsv($title);
$sql = "SELECT * FROM table_name";
$query = mysql_query($sql);
while($rs = mysql_fetch_array($query)) {
$name = $rs["name"];
$line = array('0'=>$name,'1'=>'','2'=>'','3'=>'','4'=>'');
echocsv($line);
//$content .= "\n";
}
}
The out put in a .CSV file looks like below.
head
----------
name1
name2
name3
As you can see I have put 1st colum name as 'head part1' but it will show like 'head' as its taking space as separator.
So second column name takes this.
part1,head
----------
and third column name takes this.
part2,head
----------
and so on. So how to use a comma to be separator while exporting CSV file in php ??
Don't write csv file's manually. Use the built in function.
e.g. http://uk3.php.net/manual/en/function.fputcsv.php
<?php
$delimiter = ',';
$enclosure = '"';
$list = array (
array('aaa', 'bbb', 'ccc', 'dddd'),
array('123', '456', '789'),
array('"aaa"', '"bbb"')
);
$fp = fopen('file.csv', 'w');
foreach ($list as $fields) {
fputcsv($fp, $fields, $delimiter, $enclosure);
}
fclose($fp);
?>
The above code will create a file called file.csv with your data on it. If you then want to send this file to the user as a CSV file, you can do this:
<?php
// Send the generated csv file to the browser as a download
header("Content-type: text/csv");
header("Content-Disposition: attachment; filename=file.csv");
header("Pragma: no-cache");
header("Expires: 0");
readfile('file.csv');
?>
Alternatively, you can send the CSV file to download directly without creating the file on server like this:
<?php
// mini-config
$delimiter = ',';
// Your data
$list = array (
array('aaa', 'bbb', 'ccc', 'dddd'),
array('123', '456', '789'),
array('"aaa"', '"bbb"')
);
// Send headers
header("Content-type: text/csv");
header("Content-Disposition: attachment; filename=file.csv");
header("Pragma: no-cache");
header("Expires: 0");
// Output csv data
foreach ($list as $row) {
echo implode($delimiter, $row) . "\r\n";
}
?>
Hope this helps.
