Can anyone help me how to change the content in Magento without using the command line like
php bin/magento cache:clean
php bin/magento cache:flush
I always have to run this command after any changes in Magento 2.
That's how Magento cache works and if you change anything that Magento caches, you need to clear it. You don't need to run this after modifying any PHP code, though. Check Magento Cache to learn more about Magento cache in their dev docs.
If you are debugging or in development, you can disable all cache temporarily but is highly unadvised. For example, if you are working on layouts/pages, disable
layout cache and
page cache instead of everything.
