function install_drupal
install_drupal($settings = array())
Installs Drupal either interactively or via an array of passed-in settings.
The Drupal installation happens in a series of steps, which may be spread out over multiple page requests. Each request begins by trying to determine the last completed installation step (also known as a "task"), if one is available from a previous request. Control is then passed to the task handler, which processes the remaining tasks that need to be run until (a) an error is thrown, (b) a new page needs to be displayed, or (c) the installation finishes (whichever happens first).
Parameters
$settings: An optional array of installation settings. Leave this empty for a normal, interactive, browser-based installation intended to occur over multiple page requests. Alternatively, if an array of settings is passed in, the installer will attempt to use it to perform the installation in a single page request (optimized for the command line) and not send any output intended for the web browser. See install_state_defaults() for a list of elements that are allowed to appear in this array.

Code
function install_drupal($settings = array()) { global $install_state; // Initialize the installation state with the settings that were passed in, // as well as a boolean indicating whether or not this is an interactive // installation. $interactive = empty($settings); $install_state = $settings + array('interactive' => $interactive) + install_state_defaults(); try { // Begin the page request. This adds information about the current state of // the Drupal installation to the passed-in array. install_begin_request($install_state); // Based on the installation state, run the remaining tasks for this page // request, and collect any output. $output = install_run_tasks($install_state); } catch (Exception $e) { // When an installation error occurs, either send the error to the web // browser or pass on the exception so the calling script can use it. if ($install_state['interactive']) { install_display_output($e->getMessage(), $install_state); } else { throw $e; } } // All available tasks for this page request are now complete. Interactive // installations can send output to the browser or redirect the user to the // next page. if ($install_state['interactive']) { if ($install_state['parameters_changed']) { // Redirect to the correct page if the URL parameters have changed. install_goto(install_redirect_url($install_state)); } elseif (isset($output)) { // Display a page only if some output is available. Otherwise it is // possible that we are printing a JSON page and theme output should // not be shown. install_display_output($output, $install_state); } } }
