When I running Full text RSS with PHP7.4 on ubuntu serveur 20.4 (default php version) I have the following text on the XML output :

<b>Deprecated</b>:  The each() function is deprecated. This message will be suppressed on further calls in <b>/web/outils/frss/libraries/Zend/Cache/Backend.php</b> on line <b>79</b><br />
<br />

And in my RSS reader I have the following error :

fetch error: LibXML error 5 at line 2 (column 1): Extra content at the end of the document

When I install php 7.3 with ppa of Sury it’s working properly (https://launchpad.net/~ondrej/+archive/ubuntu/php)

Is it solved in the last version ?

Hi there,

Yes, the latest version of Full-Text RSS - 3.9.6 - has been tested with PHP 7.4. Earlier versions will produce warnings or errors if run on PHP 7.4. More about version compatibility in our changelog: http://ftr.fivefilters.org/changelog.txt

OK
Apaprently I have also trouble with PHP 7.3 and cache (cf the first line of xml result

<br />

Yes, Full-Text RSS 3.8 was released in 2017. It should work with PHP 7.2. If you’re running PHP 7.3 you need at least Full-Text RSS 3.9.5.

I work with version 3.9.5. I just went to PHP 7.4 and indeed in simplepie / date.php the “implode” function is obsolete.
If we remove {public function __construct ()} the operation is correct. Work to replace implode in date processing.
This problem may be corrected in the 3.9.6

Hi there, yes, this has been fixed in 3.9.6 - which is PHP 7.4 compatible. See our changelog: http://ftr.fivefilters.org/changelog.txt
