Please share a bigger snippet of code. This error usually happens when there is a typing mistake or not closing php tags. Make sure your <?php ?> tags are opening and closing correctly and check if you are using shorthand tags like this <? } ?> If you are using it please avoid that. Also make sure that you are not mixing PHP opening and closing tags with }?> make sure there is a space between php opening and closing tags.
Using PHPSpreadsheet saving XLSX format works OK running the default code
$writer = new \PhpOffice\PhpSpreadsheet\Writer\Xlsx($spreadsheet);
$writer->save("filename.xlsx");
But if I want to have the user to select the target directory using
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="filename.xlsx"');
header('Cache-Control: max-age=0');
$writer = IOFactory::createWriter($spreadSheet, 'Xlsx');
$writer->save('php://output');
The file saves OK but Excel 2016 does not want to open it. Excel returns the following error
Excel Error
I looked through all documentation and posts but cannot find the solution.
Thanks !
Edit: Just in case, this solution does not work for me.
Edit 2: The sample provided Simple Download Xlsx works perfectly, but when doing a copy/paste for my spreadsheet, Chrome gives me a
Resource interpreted as Document but transferred with MIME type application/octet-stream
Edit 3: Used
ob_end_flush(); to clean any left over header in my code.
The file now saves OK, but needs repair when opening in Excel. Why ?
Thanks
Solution:
Bug from PhpSpreadsheet.
When using
header("Content-Type: application/vnd.ms-excel");
i.e. compatibility mode for Excel, the file opens OK.
I have created my own enduser_setup.html file nodemcu(for the enduser setup module: https://nodemcu.readthedocs.io/en/master/en/modules/enduser-setup/#enduser_setupstart).
I have added another field (beyond the ssid\password fileds):
<input id=result1 type=text autocorrect=off autocapitalize=none placeholder='Place ID' />
I want on submit to create a lua file (result1.lua) with the Get result of this field.
Tried with php:
<?php
$myfile = fopen("result1.lua", "w") or die("Unable to open file!");
$txt = $_GET["result1"];
fwrite($myfile, $txt);
fclose($myfile);
?>
Did not work :(
That is currently not possible with NodeMCU. However, there is a pending pull request that'll add this feature. It's likely going to be merged to the dev branch in the next days.
I am using Neo4j on my browser on Ubuntu. I got over 1 million nodes and I want to export them as csv file.
When return data size is small like "match n return n limit 3" there is a big fat "download csv" button I could use. But when it comes to big result set like over 1000 the shell just says "Resultset too large(over 1000 rows)" and the button doesnt show up.
How can I export csv files for large resultset?
You can also use my shell extensions to export cypher results to CSV.
See here: https://github.com/jexp/neo4j-shell-tools#cypher-import
Just provide an -o output.csv file to the import-cypher command.
Well, I just used linux shell to do all the job.
neo4j-shell -file query.cql | sed 's/|/;/g' > myfile.csv
In my case, I had also to convert from UTF-8 to ISO-8859-1 so I typed:
neo4j-shell -file query.cql | sed 's/|/;/g' | iconv -f UTF-8 -t ISO-8859-1 -o myfile.csv
PS: sed performs the replace: 's/|/;/g' means, substitute (s) all "|" to ";" even though there is more than one per line (g)
Hope this can help.
Regards
We followed the approach below using mentioned. It works very well for us.
data is formatted properly in csv format.
https://github.com/jexp/neo4j-shell-tools#cypher-import
import-cypher command from neo4J shell.
neo4j-sh (?)$ import-cypher -o test.csv MATCH (m:TDSP) return m.name
I know this is an old post, but maybe this will help someone else. For anyone using Symfony Framework, you can make a pretty simple controller to export Neo4j Cypher Queries as CSV. This uses the Graphaware NEO4J PHP OGM ( https://github.com/graphaware/neo4j-php-ogm ) to run raw cypher queries. I guess this can also easily be implemented without Symfony only using plain PHP.
Just make a form (with twig if you want):
<form action="{{ path('admin_exportquery') }}" method="get">
Cypher:<br>
<textarea name="query"></textarea><br>
<input type="submit" value="Submit">
</form>
Then set up the route of "admin_exportquery" to point to the controller. And add a controller to handle the export:
public function exportQueryAction(Request $request)
{
$query = $request->query->get('query');
$em = $this->get('neo4j.graph_manager')->getClient();
$response = new StreamedResponse(function() use($em,$query) {
$result = $em->getDatabaseDriver()->run($query);
$handle = fopen('php://output', 'w');
fputs( $handle, "\xEF\xBB\xBF" );
$header = $result->getRecords()[0]->keys();
fputcsv($handle, $header);
foreach($result->getRecords() as $r){
fputcsv($handle, $r->values());
}
fclose($handle);
});
$response->headers->set('Content-Type', 'application/force-download');
$response->headers->set('Cache-Control', 'no-store, no-cache');
$response->headers->set('Content-Disposition','attachment; filename="export.csv"');
return $response;
}
This lets you download a CSV with utf-8 characters directly from your browser and gives you all the freedom of Cypher.
IMPORTANT: This has no query check what so ever and it is a very good idea to set up appropriate security or query check before using :)
The cypher-shell:
https://neo4j.com/docs/operations-manual/current/tools/cypher-shell/
that is included in the latest versions of neo4j does this easily:
cat query.cql | cypher-shell > answer.csv
The limit 1000 is due to the browser MaxRows setting. You can change it to e.g. 10000 and thus be able to download those 10000 in one go via the download/export csv button described in the original post. On my laptop, the limit for the download button is somewhere between 10000 and 20000.
By setting the MaxRows limit to 50000 or 300000, I have been able to get the data on screen after waiting a while. Manual select, copy, and paste works. However, doing anything else than closing the browser after each query has not been possible as the browser becomes very slow.
There is another option to export the data as CSV using the cURL command with http/https neo4j transaction/commit endpoint.
here is an example on how to do that.
curl -H accept:application/json -H content-type:application/json \
-d '{"statements":[{"statement":"MATCH (p1:PROFILES)-[:RELATION]-(p2) RETURN ... LIMIT 4"}]}' \
http://localhost:7474/db/data/transaction/commit \
| jq -r '(.results[0]) | .columns,.data[].row | #csv'
and this command uses jq. make sure jq is installed in your machine and this converts the results to the CSV format.
Note: You may need to pass Authorization in the header for authentication.
Just pass -H 'Authorization: Basic XXXXX=' \ to avoid 401
here is the blog with a detailed explanation.

I am using SimplePie to Parse an RSS feed, and I am getting the following output:
Don't forget our "Spot It, Post It" .....
My code is:
<?php
header('Content-type:text/html; charset=utf-8');
require_once('rss/simplepie.inc');
// We'll process this feed with all of the default options.
$feed = new SimplePie();
// Set which feed to process.
$feed->set_feed_url('FeedURL');
$feed->enable_cache(true);
$feed->set_cache_duration(3600);
$feed->set_cache_location('cache');
$feed->init();
$feed->handle_content_type();
?>
I'm using HTML5 Doctype AND I also have: <meta charset="charset=utf-8">
I've looked it up and everything talks about changing the charset to UTF-8 which I clearly have.. so I'm not too sure what else is causing this.
Any ideas?
I don't know if you've managed to fix this, but thought I'd share my solution with anyone else who is looking. I had the same problem - the characters were being 'corrupted' in the feed. My code initially (with the problem) was:
<?php
include_once $_SERVER['DOCUMENT_ROOT'] . '/inc/simplepie.inc';
$feed = new SimplePie('http://domain.wordpress.com/feed/');
?>
Seeing the post above, I tried adding the following header and it worked!
<?php
header('Content-type:text/html; charset=utf-8');
include_once $_SERVER['DOCUMENT_ROOT'] . '/inc/simplepie.inc';
$feed = new SimplePie('http://domain.wordpress.com/feed/');
?>
I hope this helps someone else experiencing the same problems.
Does this happen with every feed? Or just one particular feed? It might be the feed itself. You can use $item->get_content() and look at the content of the feed directly if the description itself is proving problematic. Sometimes it is necessary to do processing on information from a feed or web API, there is PHP code and examples for stripping and replacing characters, the News Blocks 2.0 demo on the SimplePie site has some cleaning code I've been using a lot recently.
Good luck.
