Hi,

I 'm trying to install Slim 3 by composer, but the composer returns error in the version of PHP:

- slim/slim 3.5.0 requires php \>=5.5.0 -\> your PHP version (5.4.16) does not satisfy that requirement.

My PHP version is 5.6.18 .

Core:  
PHP Version 5.6.18

Where the composer checks the version ?

Thanks

Doesn’t sound like your server is setup correctly.

composer uses the `php` command on the CLI… it’s possible you have `php56` installed in which case composer is not going to work.

What does `php -v` say?

I entered in contact with de support of server and the server configuration is correct now.

Thanks
