How to Check User Password from Text File with PHP

Ensuring the security of user passwords is crucial in the digital age, where cyber threats are rampant. If you need to check a user's password from a text file using PHP, you can follow these steps:

1. Read the text file containing passwords and usernames.
2. Retrieve the user-entered password.
3. Compare the user-entered password with the stored passwords in the text file.
4. If there is a match, the password is correct; otherwise, it is incorrect.

It is essential to hash the passwords before storing them in the text file to enhance security. PHP provides functions like password_hash() and password_verify() for secure password hashing and validation.
