I'm working with php version 7.4.9, so it appears that the update to using psr/log version 2.0/3.0 which requires php 8.0 is breaking things. Is there a way around this without updating my version of php?

Hi,

I am using Symfony 5.3.10, api-platform 2.6, and php 8.0.3, when run the server and go to the home page, i got this type of syntax error , i tried to solve this problem by changing the version of psr/log(1.1.4 => 2.0.0) but, it doesn't work and its change the symfony error to PHP error, is there any other solutions for this?

I have some syntax errors from symfony vendor when i'm trying to composer install my project.

Parse error: syntax error, unexpected '|', expecting variable (T_VARIABLE) vendor\psr\log\src\LoggerInterface.php on line 30

With several search, I saw the problem is from PHP version (have to be > 7.1), but actually my version is 7.4.9, this is a local machine, i'm working with WAMP on Windows. Symfony 4.4 version. Already tried to delete vendor, .lock...

Here the php version from phpinfo()

Here php version from wamp

Here php version from CLI php-v

Here my composer.json

Hi Didier,

Thank you for raising your concern.

I completely understand your concern. However, since the issue is more on client library configuration, then I would suggest to reach out to the author of the client library as they are more equipped here. You can reach out to the author of the PHP client library via this link.

Let me know if you have further questions.

Regards,

Ernie John Blanca Tacata Google Ads API Team
