How can folders containing log files be secured against unauthorized access in PHP applications?

To secure folders containing log files against unauthorized access in PHP applications, you can use an .htaccess file to restrict access to the folder by denying all requests except those coming from specific IP addresses or by requiring authentication. This ensures that only authorized users can access the log files.

# Create an .htaccess file in the log folder
# Deny access to all users
Order deny,allow
Deny from all

# Allow access only from specific IP addresses
Allow from 192.168.1.1
Allow from 10.0.0.1

# Alternatively, require authentication to access the log files
AuthType Basic
AuthName "Restricted Area"
AuthUserFile /path/to/.htpasswd
Require valid-user
