I am new to PHP and struggling,I have an HTML form kind of login form,I want to store that input values from html form to a txt file,These all files are hosted on free hosting site(i made it for learning purpose).I have tried lots of threads to achieve that but none of them worked for me till now.So can anyone please help me,I have tried as in code.whihc is not working

AN HTMl form,a php code file and a txt file,Three of them are hosted on a free web hosting 000webhost.

Login Name: Password:

php file

I have uploaded data.txt already.

This is most likely a permission issue. Check write permission with is_writable or enable error output with ini_set('display_errors', true);

Change permissions for data.txt accordingly.
