Public_html is a commonly used name for the web document root directory in many web hosting environments. It represents the directory from which a user’s web server serves files for that account. On Linux-based shared hosting that uses cPanel, the path is typically /home/username/public_html. The public_html directory is the web-visible portion of the user’s home directory, and files placed there are accessible via the user’s domain or subdomain.

Files and structure placed in public_html become part of the website. A request for a domain maps to this directory, and default index files such as index.html or index.php are served if present. Subfolders inside public_html translate to corresponding subpaths in the URL, for example public_html/blog/ corresponds to http://yourdomain.com/blog/.

Permissions and server behavior are important. Directories in public_html are usually 755 and files 644, with the account owner as the file owner. Executable scripts and uploads should be kept within appropriate folders, and avoid granting excessive permissions (for example, avoid 777). Web servers typically rely on .htaccess or server configuration for local rules, URL rewriting, and access controls.

Security considerations include protecting sensitive data, restricting directory listing, and keeping software up to date. Do not store credentials or private data in publicly accessible folders, and use proper permissions and access controls to prevent unintended access.

Variants exist across hosts. Some environments use www, htdocs, or httpdocs as the web root with a similar purpose. The key concept is the same: a designated public directory within a hosting account that serves web content to visitors.
