I am trying to output the results of a PostgreSQL query to CSV format using PHP.
On the main page is a link that sends the SQL statements as a string to another function in another PHP class, which in turn takes the SQL and executes the query using pg_query() and return the result sets.
My problem is that when I open the CSV file, all the results of my query are there, but at the end of the file I see the HTML code from the page that sent the query.
I looked at several StackOverflow posts, but to no avail.
Here is my code:
Main class:
$o .= '<p>You can convert the result set to CSV format to be opened in Excel.</p>';
$link = array('op1' => 'PatternExport', 'op2' => 'outputToCSV', 'id' => $pattern_id, 'data' => $pattern_SQL);
$o .= 'Download Query Results as CSV File';
Receiving class:
function outputToCSV()
{
$ptid = $this->oQS->getValue('id');
$sql = $this->oQS->getValue('data');
$href = $this->oQS->buildEncryptedURL(array('op1'=>'PatternManager', 'op2'=>'listPatterns'),'/aatsc/index.php');
$result = pg_query($sql);
// filename for download
$filename = "query_results_" . date('Ymd') . "_" . $ptid . ".csv";
$output = fopen('php://temp/maxmemory:' . (12*1024*1024), 'rw+');
foreach(pg_fetch_assoc($result,0) AS $field=>$value)
{
$output .= '' . $field . ',';
}
$output = rtrim($output,',') . "\n";
for($i=0;$i<pg_num_rows($result);$i++)
{
foreach(pg_fetch_assoc($result,$i) AS $field=>$value)
$output .= '' . $value . ',';
$output = rtrim($output,',') . "\n";
}
header("Content-Type: application/vnd.ms-excel;");
header("Content-Disposition: attachment; filename=\"$filename\";");
header("Pragma: no-cache");
print($output);
//$href = $this->oQS->buildEncryptedURL(array('op1'=>'PatternManager', 'op2'=>'listPatterns'),'/aatsc/index.php');
//header("Location: $href");
}
Could you tell me whether I am using the right approach to export query results to CSV, and what in my code is causing the whole HTML code to be streamed?
Thanks
You're generating $output twice, if you remove the foreach loop & fopen line, it should work.
You merely just need to issue the SQL COPY statement as follows:
COPY (select * from tbl) to stdout with csv header
resulting in:
col1,col2,col3

I'm trying to use PHP Simple HTML Dom Parser to parse some information from SQL query results. But it seems, that there is some HUGE memory problem with it. I create an html table using the SQL query results and then export the html table to a csv file. I am really new to this so my code is not the most efficient one. When I my query results are small the csv file is created successfully. But when the query results are large, the exported csv file does not have any sql results and instead shows this :
Fatal error: Call to a member function find() on boolean in /opt/lampp/htdocs/test.php on line 101
This is my function that takes the sqlresult and creates an html table and then exports it into a csv file:
echo sql_to_html_table($sqlresult, $delim="\n" );
function sql_to_html_table($sqlresult, $delim="\n") {
// starting table
include_once('simple_html_dom.php');
$htmltable = "<table>" . $delim ;
$counter = 0 ;
// putting in lines
//while( $row = $sqlresult->mysqli_fetch_assoc() ){
while($row = mysqli_fetch_assoc($sqlresult)) {
if ( $counter===0 ) {
// table header
$htmltable .= "<tr>" . $delim;
foreach ($row as $key => $value ) {
$htmltable .= "<th>" . $key . "</th>" . $delim ;
}
$htmltable .= "</tr>" . $delim ;
$counter = 22;
}
// table body
$htmltable .= "<tr>" . $delim ;
foreach ($row as $key => $value ) {
$htmltable .= "<td>" . $value . "</td>" . $delim ;
}
$htmltable .= "</tr>" . $delim ;
}
// closing table
$htmltable .= "</table>" . $delim ;
// return
//return( $htmltable ) ;
$html = str_get_html($htmltable);
header('Content-type: application/ms-excel');
header('Content-Disposition: attachment; filename=sample.csv');
$fp = fopen("php://output", "w");
foreach($html->find('tr') as $element)
{
$td = array();
foreach( $element->find('th') as $row)
{
$td [] = $row->plaintext;
}
fputcsv($fp, $td);
$td = array();
foreach( $element->find('td') as $row)
{
$td [] = $row->plaintext;
}
fputcsv($fp, $td);
}
fclose($fp);
}
I have tried throwing an exception after $html = str_get_html($htmltable); like this:
if (!str_get_html($htmltable)) {
throw new exception('exception') ;
}
and when I try to run the code my browser gives me this error:
Fatal error: Uncaught exception 'Exception' with message 'exception' in /opt/lampp/htdocs/test.php:96 Stack trace: #0 /opt/lampp/htdocs/test.php(62): sql_to_html_table(Object(mysqli_result), '\n') #1 {main} thrown in /opt/lampp/htdocs/test.php on line 96
Looking at a copy of simple_html_dom.php from SourceForge, this sounds like expected behavior for a sufficiently big HTML string. I see that str_get_html() has a check that will cause it to return false if the size of the string is greater than MAX_FILE_SIZE. And MAX_FILE_SIZE is defined with:
define('MAX_FILE_SIZE', 600000);
So it looks like simple_html_dom won't handle any string bigger than about 600kb. Since that's a built-in limitation, I guess your options are to either try to change the limit and see what happens or use a different library.
Alternatively, you could just skip the HTML portion altogether. If you need to generate the HTML for other purposes, that's fine, but there's no reason you can't bypass this problem by just building the CSV directly from the database results rather than from the HTML.
Maybe this is a little easier to understand:
function sql_to_csv($sqlresult, $delim = "\n") {
// Loop each result into a csv row string
while($row = mysqli_fetch_assoc($sqlresult)) {
// Create/reset a var to hold the csv row content
$csvRow = '';
// Append each column value comma separated
// Be warned of column values containing commas
foreach ($row AS $columnValue) {
$csvRow .= $columnValue . ',';
}
// Remove the trailing comma from the final column
rtrim($csvRow, ',');
// Send your CSV row to the browser
echo $csvRow . $delim;
}
header('Content-type: text/csv');
header('Content-Disposition: attachment; filename=sample.csv');
}
There are various issues with this approach not limited to, large output buffers, columns with multi-commas ...etc I recognise these problems but wanted to give an early approach to the solution instead of a large block of text.
The easiest way to debug PHP code is to run it with de-bugg outputting, the following may help you if the above is not useful:
var_dump($variable);
exit;
This will enable you to see the contents of the variable at run time, and may give better indication to your exception, given the line-number in your exceptions.
Goodluck.
I'm trying to generate a CSV file on the fly, depending on what the user selects as report output. Retrieving the data and writing it to a file using CakeResponse is done, however I'm struggling to set the file extension to '.csv', the file get downloaded as a normal text file.
CakePHP documentation suggests I do this:
$this->response->type('csv');
..but even this is not working, I'm still getting a text file. Can anyone shed some light? Please note, I'm not looking for new methods to generate a CSV file, I just want to change the extension. Thank you.
This is how I download the file:
$this->response->body($this->constructFileBody($logs));
return $this->response;
This is the method 'constructFileBody', although I think its beyond the scope of this question:
public function constructFileBody($logs = array()){
$content = "";
for($i = 0; $i < count($logs); $i++){
$row = $logs[$i]['EventLog'];
$line = $row['description'] . "," . $row['user'] . "," . $row['affected_user'] . "," . $row['report_title'] . "," . $row['date_created'] . "\n";
$content = $content . $line;
}
return $content;
}
As i saw your code, I don't think you used the header anywhere, try this code:
//create a file
$filename = "export_".date("Y.m.d").".csv";
$csv_file = fopen('php://output', 'w');
header('Content-type: application/csv');
header('Content-Disposition: attachment; filename="'.$filename.'"');
$results = $this->ModelName->query($sql); // This is your sql query to pull that data you need exported
//or
$results = $this->ModelName->find('all', array());
// The column headings of your .csv file
$header_row = array("ID", "Received", "Status", "Content", "Name", "Email", "Source", "Created");//columns you want in csv file
fputcsv($csv_file,$header_row,',','"');
// Each iteration of this while loop will be a row in your .csv file where each field corresponds to the heading of the column
foreach($results as $result)
{
// Array indexes correspond to the field names in your db table(s)
$row = array(
$result['ModelName']['id'],
$result['ModelName']['received'],
$result['ModelName']['status'],
$result['ModelName']['content'],
$result['ModelName']['name'],
$result['ModelName']['email'],
$result['ModelName']['source'],
$result['ModelName']['created']
);
fputcsv($csv_file,$row,',','"');
}
fclose($csv_file);
Now look at your code and get the line of code mine which needs to be replaced.
I want to download a .csv file through link.For that a Download link is defined in a template file.
To generate .csv file I have written a piece of code as follows.
public function loadPartnerApplicantData() {
$inboundBo = BoFactory::getInboundHttpRequestBo();
$fileType = $inboundBo->getSanitizedGetParam('f');
$formId = $inboundBo->getSanitizedGetParam('fid');
ServiceFactory::getFormService()->loadFormDetails($formId);
$dbTable = BoFactory::getFormBo()->getFormDbTable($formId);
$formName = slugify(BoFactory::getFormBo()->getFormName());
$fileName = $formName . "." . time();
$fieldMasterSqlQuery = "SELECT field_name,field_label FROM" . FORM_FIELDS_MASTER_v2 . "where form_id='$formId' order by serial_no";
$fieldMasterSqlQueryStatus = mysql_query(mysql_fetch_assoc($fieldMasterSqlQuery));
$csvHeader = "";
$fieldNameArray = array();
foreach ($fieldMasterSqlQueryStatus as $key => $value) {
if ($value['field_name'] == 'declaration' || $value['field_name'] == 'docPicture') {
continue;
}
$csvHeader.= "\"{$value['field_label']}\";";
$fieldNameArray[] = $value['field_name'];
}
$queryString = implode(",", $fieldNameArray);
$dbTableSqlQuery = "SELECT $queryString FROM `$dbTable`";
$dbTableSqlQueryStaus = mysql_query(mysql_fetch_assoc($dbTableSqlQuery));
ef_clearBuffer();
// To generate csv
header("Content-type: text/csv");
header("Content-Disposition: attachment; filename=$fileName.csv");
header("Pragma: no-cache");
header("Expires: 0");
echo($csvHeader);
foreach ($dbTableSqlQueryStaus as $applicantData) {
echo "\n";
foreach ($fieldNameArray as $fieldName) {
echo "\"$applicantData[$fieldName]\";";
}
echo "\n";
}
}
And the required .csv is generated .
But at the end of .csv file HTML tags of the browser is getting displayed. which should not be there.
Please suggest me to remove the html content from the generated .csv file.
Thanks in advance.
Since your function handles the request till the end (i.e., delivers all data), and you don't want the framework (whichever you're using) to continue processing, add
exit(0);
as last line of your function. That will halt the processing after the content is delivered and prevent the framework/environment from sending additional data.
Maybe you already had some echo commands before the header manipulation, then the .csv file which you want to download will contains all strings you have written before.
Alright, I'm starting to go a little crazy...
jQuery Table to CSV export
I'm looking at that thread.
It does work, but the output does everything by each LINE not by the HTML table rows. For example, I have an address that is in one HTML cell:
1234 Berryman Lane
Atlanta, GA 12345
Unit # 54A
That will be THREE rows when it outputs to excel, instead of one cell, with returns in it.
Further, there's no way to strip out the HTML that is inside of the HTML cells with that solution, as far as I know...
Finally, Excel gives a warning when opening that file.
What I'm getting at, is that I'd rather just have something that can take the inner most data in the HTML cells (not including HTML inside of a cell), and rip it to CSV. Is there anything that does this well these days?
UPDATE
Well, I just found the best thing yet, this is pretty perfect:
$table = 'myTable';
$file = 'exportFile';
$result = mysql_query("SHOW COLUMNS FROM ".$table."");
$i = 0;
if (mysql_num_rows($result) > 0) {
while ($row = mysql_fetch_assoc($result)) {
$csv_output .= "\"" . $row['Field']."\",";
$i++;
}
}
$csv_output .= "\n";
$values = mysql_query("SELECT * FROM ".$table."");
while ($rowr = mysql_fetch_row($values)) {
for ($j=0;$j<$i;$j++) {
$csv_output .= "\"" . $rowr[$j]."\",";
}
$csv_output .= "\n";
}
$filename = $file."_".date("Y-m-d_H-i",time());
header("Content-type: application/vnd.ms-excel");
header("Content-disposition: csv" . date("Y-m-d") . ".csv");
header( "Content-disposition: filename=".$filename.".csv");
print $csv_output;
exit;
I think this is my keeper. It goes to a CSV file with no issues, loads in Excel with no issues, it's my dream come true!
well, you can always use the same markup in excel as it can render html if you use the .xls file type, render the html table and change the content type to "application/vnd.ms-excel" specify a filename for that response as *.xls and you should have a usable excel sheet.
If there are no dobule quotes in the data, you can wrap the content of each cell in double quotes so your data looks like:
"...","...","..."
Now you can have commas in the data. You may also need to deal with new lines and returns in the data, probably best to remove them completely but that's up to you.
Thanks for all suggestions. As stated in my edited post, this script below was a great solution:
$table = 'myTable';
$file = 'exportFile';
$result = mysql_query("SHOW COLUMNS FROM ".$table."");
$i = 0;
if (mysql_num_rows($result) > 0) {
while ($row = mysql_fetch_assoc($result)) {
$csv_output .= "\"" . $row['Field']."\",";
$i++;
}
}
$csv_output .= "\n";
$values = mysql_query("SELECT * FROM ".$table."");
while ($rowr = mysql_fetch_row($values)) {
for ($j=0;$j<$i;$j++) {
$csv_output .= "\"" . $rowr[$j]."\",";
}
$csv_output .= "\n";
}
$filename = $file."_".date("Y-m-d_H-i",time());
header("Content-type: application/vnd.ms-excel");
header("Content-disposition: csv" . date("Y-m-d") . ".csv");
header( "Content-disposition: filename=".$filename.".csv");
print $csv_output;
exit;
I think this is my keeper. It goes to a CSV file with no issues, loads in Excel with no issues, it's my dream come true!
I have some PHP code that runs a query on a database, saves the results to a csv file, and then allows the user to download the file. The problem is, the csv file contains page HTML around the actual csv content.
I've read all the related questions here already, including this one. Unfortunately my code exists within Joomla, so even if I try to redirect to a page that contains nothing but headers, Joomla automatically surrounds it with its own navigation code. This only happens at the time of download; if I look at the csv file that's saved on the server, it does not contain the HTML.
Can anyone help me out with a way to force a download of the actual csv file as it is on the server, rather than as the browser is editing it to be? I've tried using the header location, like this:
header('Location: ' . $filename);
but it opens the file in the browser, rather than forcing the save dialog.
Here's my current code:
//set dynamic filename
$filename = "customers.csv";
//open file to write csv
$fp = fopen($filename, 'w');
//get all data
$query = "select
c.firstname,c.lastname,c.email as customer_email,
a.email as address_email,c.phone as customer_phone,
a.phone as address_phone,
a.company,a.address1,a.address2,a.city,a.state,a.zip, c.last_signin
from {$dbpre}customers c
left join {$dbpre}customers_addresses a on c.id = a.customer_id order by c.last_signin desc";
$votes = mysql_query($query) or die ("File: " . __FILE__ . "<br />Line: " . __LINE__ . "<p>{$query}<p>" . mysql_error());
$counter = 1;
while ($row = mysql_fetch_array($votes,1)) {
//put header row
if ($counter == 1){
$headerRow = array();
foreach ($row as $key => $val)
$headerRow[] = $key;
fputcsv($fp, $headerRow);
}
//put data row
fputcsv($fp, $row);
$counter++;
}
//close file
fclose($fp);
//redirect to file
header("Content-type: application/octet-stream");
header("Content-Disposition: attachment; filename=".$filename);
header("Content-Transfer-Encoding: binary");
readfile($filename);
exit;
EDITS
Full URL looks like this:
http://mysite.com/administrator/index.php?option=com_eimcart&task=customers
with the actual download link looking like this:
http://mysite.com/administrator/index.php?option=com_eimcart&task=customers&subtask=export
MORE EDITS
Here's a shot of the page that the code is on; the generated file still is pulling in the html for the submenu. The code for the selected link (Export as CSV) is now
index.php?option=com_eimcart&task=customers&subtask=export&format=raw
Now here is a screenshot of the generated, saved file:
It shrank during the upload here, but the text highlighted in yellow is the html code for the subnav (list customers, add new customer, export as csv). Here's what my complete code looks like now; if I could just get rid of that last bit of html it would be perfect.
$fp= fopen("php://output", 'w');
$query = "select c.firstname,c.lastname,c.email as customer_email,
a.email as address_email,c.phone as customer_phone,
a.phone as address_phone, a.company, a.address1,
a.address2,a.city,a.state,a.zip,c.last_signin
from {$dbpre}customers c
left join {$dbpre}customers_addresses a on c.id = a.customer_id
order by c.last_signin desc";
$votes = mysql_query($query) or die ("File: " . __FILE__ . "<br />Line: " . __LINE__ . "<p>{$query}<p>" . mysql_error());
$counter = 1;
//redirect to file
header("Content-type: application/octet-stream");
header("Content-Disposition: attachment; filename=customers.csv");
header("Content-Transfer-Encoding: binary");
while ($row = mysql_fetch_array($votes,1)) {
//put header row
if ($counter == 1){
$headerRow = array();
foreach ($row as $key => $val)
$headerRow[] = $key;
fputcsv($fp, $headerRow);
}
//put data row
fputcsv($fp, $row);
$counter++;
}
//close file
fclose($fp);
UPDATE FOR BJORN
Here's the code (I think) that worked for me. Use the RAW param in the link that calls the action:
index.php?option=com_eimcart&task=customers&subtask=export&format=raw
Because this was procedural, our link was in a file called customers.php, which looks like this:
switch ($r['subtask']){
case 'add':
case 'edit':
//if the form is submitted then go to validation
include("subnav.php");
if ($r['custFormSubmitted'] == "true")
include("validate.php");
else
include("showForm.php");
break;
case 'delete':
include("subnav.php");
include("process.php");
break;
case 'resetpass':
include("subnav.php");
include("resetpassword");
break;
case 'export':
include("export_csv.php");
break;
default:
include("subnav.php");
include("list.php");
break;
}
So when a user clicked on the link above, the export_csv.php file is automatically included. That file contains all the actual code:
<?
header("Content-type: application/octet-stream");
header("Content-Disposition: attachment; filename=customers.csv");
header("Content-Transfer-Encoding: binary");
$fp= fopen("php://output", 'w');
//get all data
$query = "select
c.firstname,c.lastname,c.email as customer_email,
a.email as address_email,c.phone as customer_phone,
a.phone as address_phone,
a.company,a.address1,a.address2,a.city,a.state,a.zip, c.last_signin
from {$dbpre}customers c
left join {$dbpre}customers_addresses a on c.id = a.customer_id order by c.last_signin desc";
$votes = mysql_query($query) or die ("File: " . __FILE__ . "<br />Line: " . __LINE__ . "<p>{$query}<p>" . mysql_error());
$counter = 1;
while ($row = mysql_fetch_array($votes,1)) {
//put header row
if ($counter == 1){
$headerRow = array();
foreach ($row as $key => $val)
$headerRow[] = $key;
fputcsv($fp, $headerRow);
}
//put data row
fputcsv($fp, $row);
$counter++;
}
//close file
fclose($fp);
This is a piece of sample code that I just cooked up to help you out. Use it as an action method in your controller.
function get_csv() {
$file = JPATH_ADMINISTRATOR . DS . 'test.csv';
// Test to ensure that the file exists.
if(!file_exists($file)) die("I'm sorry, the file doesn't seem to exist.");
// Send file headers
header("Content-type: text/csv");
header("Content-Disposition: attachment;filename=test.csv");
// Send the file contents.
readfile($file);
}
This alone will not be enough, because the file you download will still contain the surrounding html. To get rid of it and only receive the csv file's contents you need to add format=raw parameter to your request. In my case the method is inside the com_csvexample component, so the url would be:
/index.php?option=com_csvexample&task=get_csv&format=raw
EDIT
In order to avoid using an intermediate file substitute
//set dynamic filename
$filename = "customers.csv";
//open file to write csv
$fp = fopen($filename, 'w');
with
//open the output stream for writing
//this will allow using fputcsv later in the code
$fp= fopen("php://output", 'w');
Using this method you have to move the code that sends headers before anything is written to the output. You also won't need the call to the readfile function.
Add this method to your controller:
function exportcsv() {
$model = & $this->getModel('export');
$model->exportToCSV();
}
Then add a new model called export.php, code below. You will need to change or extend the code to your situation.

Good luck!
You can use Apache's mod_cern_meta to add HTTP headers to static files. Content-Disposition: attachment. The required .htaccess and .meta files can be created by PHP.
Another way to output CSV data in a Joomla application is to create a view using CSV rather than HTML format. That is, create a file as follows:
components/com_mycomp/views/something/view.csv.php
And add content similar to the following:
<?php
// No direct access
defined('_JEXEC') or die;
jimport( 'joomla.application.component.view');
class MyCompViewSomething extends JViewLegacy // Assuming a recent version of Joomla!
{
function display($tpl = null)
{
// Set document properties
$document = &JFactory::getDocument();
$document->setMimeEncoding('text/csv');
JResponse::setHeader('Content-disposition', 'inline; filename="something.csv"', true);
// Output UTF-8 BOM

Then you can create file download links as follows:
/index.php?option=com_mycomp&view=something&format=csv
Now, you would be right to question the 'inline' part in the Content-disposition. If I recall correctly when writing this code some years ago, I had problems with the 'attachment' option. This link which I just googled now seemed familiar as the driver for it: https://dotanything.wordpress.com/2008/05/30/content-disposition-attachment-vs-inline/ . I've been using 'inline' ever since and am still prompted to save the file appropriately from any browsers I test with. I haven't tried using 'attachment' any time recently, so it may work fine now of course (the link there is 7 years old now!)
