Let's say user1 writes "Hello" in a textbox and submits it, and user2 writes later that day " World" and submits it. How can i code it so their inputs get sent to my .txt file? So the .txt file should look like this: "Hello World". This might be a bit complicated to answer. If so, could anyone point me in the right direction or give me any good links / tutorials? And second question: Do I need to learn MySQL for this?

  • `file_put_contents` with `FILE_APPEND` might be useful. As for `Do I need to learn MySQL` - IMO You would be better using a database than a textfile perhaps but that is an opinion based question/answer – Professor Abronsius Mar 25 '21 at 18:11

  • Please read [How much research effort is expected of Stack Overflow users?](https://meta.stackoverflow.com/questions/261592/how-much-research-effort-is-expected-of-stack-overflow-users). If you just do some research for each step (like "forms in php", "store text in file with php" and so on) you would find _many many_ tutorials. And Mysql is a database and doesn't have anything to do with what you're asking (even though I agree with the first comment, it would be preferred to use a database over text files) – M.
