/* This file contains functions that are specifically done by administrators.

||
|
updateSettingsFile() function, but it shouldn't be used often anyway.
|
||
|
|
||
|
void getServerVersions(array checkFor)
|
||
|
- get a list of versions that are currently installed on the server.
|
||
|
|
||
|
void getFileVersions(array versionOptions)
|
||
|
- get detailed version information about the physical SMF files on the
|
||
|
server.
|
||
|
- the input parameter allows to set whether to include SSI.php and
|
||
|
whether the results should be sorted.
|
||
|
- returns an array containing information on source files, templates
|
||
|
and language files found in the default theme directory (grouped by
|
||
|
language).
|
||
|
|
||
|
void updateSettingsFile(array config_vars)
|
||
|
- updates the Settings.php file with the changes in config_vars.
|
||
|
- expects config_vars to be an associative array, with the keys as the
|
||
|
variable names in Settings.php, and the values the varaible values.
|
||
|
- does not escape or quote values.
|
||
|
- preserves case, formatting, and additional options in file.
|
||
|
- writes nothing if the resulting file would be less than 10 lines
|
||
|
in length (sanity check for read lock.)
|
||
|
|
||
|
void updateAdminPreferences()
|
||
|
- saves the admins current preferences to the database.
|
||
|
|
||
|
void emailAdmins(string $template, array $replacements = array(), additional_recipients = array())
|
||
|
- loads all users who are admins or have the admin forum permission.
|
||
|
- uses the email template and replacements passed in the parameters.
|
||
|
- sends them an email.
|
||
|
|
||
|
bool updateLastDatabaseError()
|
||
|
- attempts to use the backup file first, to store the last database error
|
||
|
- and only update Settings.php if the first was successful.
