Determines the installation profile to use in the installer.

Depending on the context from which it's being called, this method may be used to:

• Automatically select a profile under certain conditions.
• Indicate which profile has already been selected.
• Indicate that a profile still needs to be selected.

A profile will be selected automatically if one of the following conditions is met. They are checked in the given order:

• Only one profile is available.
• A specific profile name is requested in installation parameters:
  • For interactive installations via request query parameters.
  • For non-interactive installations via install_drupal() settings.
• One of the available profiles is a distribution. If multiple profiles are distributions, then the first discovered profile will be selected.
• Only one visible profile is available.

Parameters

array $install_state: The current installer state, containing a 'profiles' key, which is an associative array of profiles with the machine-readable names as keys.

Return value

string|null|false The machine-readable name of the selected profile or NULL if no profile was selected or FALSE if the site has no profile.
