function install_verify_requirements
install_verify_requirements(&$install_state)
Verifies the requirements for installing Drupal.
Parameters
$install_state: An array of information about the current installation state.
Return value
A themed status report, or an exception if there are requirement errors. If there are only requirement warnings, a themed status report is shown initially, but the user is allowed to bypass it by providing 'continue=1' in the URL. Otherwise, no output is returned, so that the next task can be run in the same page request.

If there are only warnings, skip // them if the user has provided a URL parameter acknowledging the warnings // and indicating a desire to continue anyway.

': ' . $requirement['value'] . "\n\n" . $requirement['description']; } } if (!empty($failures)) { throw new Exception(implode("\n\n", $failures)); } } } }
