Resolved errors raised by PHPStan

[ayushmansatpathy]

PHPStan (the new static analysis tool) raised errors in incorrect variable case, unused functions, and incorrect number of parameters. This was manually fixed to ensure that PHPStan did not raise any other errors when it analysed the resources folder.

Additionally, this commit includes the installation of psalm.dev, another static analysis tool.
