Hi,
it would help with troubleshooting if you could provide more details.
In which file does the error occur? What API request are you doing exactly?

Hello,

As i writed, i used exactly the same script as Matomo provide us.
But just realized that it is supposed to be the right ouput, but i can't be real ?

Here the script i've used:

<?php
exit; // REMOVE this line to run the script

// this token is used to authenticate your API request.
// You can get the token on the API page inside your Matomo interface
$token_auth = 'my api token';

// we call the REST API and request the 100 first keywords for the last month for the idsite=7
$url = "my url";
$url .= "?module=API&method=Referrers.getKeywords";
$url .= "&idSite=7&period=month&date=yesterday";
$url .= "&format=PHP&filter_limit=20";
$url .= "&token_auth=$token_auth";

$fetched = file_get_contents($url);
$content = unserialize($fetched);

// case error
if (!$content) {
    print("Error, content fetched = " . $fetched);
}

print("<h1>Keywords for the last month</h1>\n");
foreach ($content as $row) {
    $keyword = htmlspecialchars(html_entity_decode(urldecode($row['label']), ENT_QUOTES, 'UTF-8'), ENT_QUOTES, 'UTF-8');
    $hits = $row['nb_visits'];

    print("<b>$keyword</b> ($hits hits)<br>\n");
}

Take a look on that: https://developer.matomo.org/guides/querying-the-reporting-api

This is crazy that Matomo developer provide us with error ? I just can't believe that. It should be a mistake.

Hi,

The PHP error doesn't happen in Matomo, but in the script that makes the HTTP request to the Matomo API.

It seems like the API doesn't return any keywords and therefore you can't loop over them.
Check if there are keywords in your Matomo instance.

Hello, thanks for your help, really appreciated.

But did you notice on the URL i provide you that Matomo team say that this error should be the output.

And yes i have keywords, also, tried with the previous install i had, gived me the same error. That why i reainstall it.

And yes, the error is a part of Matomo source, even if i call the API outside the URL (but same IP), so problem is from Matomo. I run dedicated server, i can confirm you that i enabled all function to make it work.

Take a look on internet which cause this problem, look like this come from an empty string. But yes i have keywords and atleast, it should probably return something like "No data" instead of throwing error like this lol.

You are right that this example is a bit outdated.

I'd recommend you to simply use API as described in https://developer.matomo.org/api-reference/reporting-api to fetch JSON data and then handle this in your script.

You're the man.

Thanks alot bro.
