We've been working with our hoster to install composer on a centos 5 with php 5.3.9, and though we get no installation errors, running composer with any command always gives us the following:
-bash-3.2$ composer help install
??+?-bash-3.2$
always this funny ??+? response.
This also happen when I download a composer.phar manually, and if I run composer.phar over php. Always the same issue. The provider technicians tried to install it with admin privileges and they also get this error. any ideas?
I fixed the problem by running:
curl -s https://getcomposer.org/installer | php -- --check
It gave me some php.ini settings I needed.
Then I ran composer using:
php -c pathToPhp.ini pathToComposer.phar
