Thank you, Actually brew post-install shivammathur/php/php@7.4 got and error
Error: Unknown command: post-install but after updating my shell profile ~/.bash_profile with export PATH="/usr/local/opt/php@7.4/bin:$PATH" iam able to run php@7.4

[shivammathur]

It should be brew postinstall shivammathur/php/php@7.4 without the -.

In case you want to switch to other versions, please run the postinstall command and remove php@7.4's bin from the path, or else it will always run php 7.4.
