It provides all of the following functions: void updateStats(string statistic, string condition = '1') - statistic can be 'member', 'message', 'topic', or 'postgroups'. - parameter1 and parameter2 are optional, and are used to update only those stats that need updating. - the 'member' statistic updates the latest member, the total member count, and the number of unapproved members. - 'member' also only counts approved members when approval is on, but is much more efficient with it off. - updating 'message' changes the total number of messages, and the highest message id by id_msg - which can be parameters 1 and 2, respectively. - 'topic' updates the total number of topics, or if parameter1 is true simply increments them. - the 'postgroups' case updates those members who match condition's post-based membergroups in the database (restricted by parameter1). void updateMemberData(int id_member, array data) - updates the columns in the members table. - id_member is either an int or an array of ints to be updated. - data is an associative array of the columns to be updated and their respective values. - any string values updated should be quoted and slashed. - the value of any column can be '+' or '-', which mean 'increment' and decrement, respectively. - if the member's post number is updated, updates their post groups. - this function should be used whenever member data needs to be updated in place of an UPDATE query. void updateSettings(array changeArray, use_update = false) - updates both the settings table and $modSettings array. - all of changeArray's indexes and values are assumed to have escaped apostrophes (')! - if a variable is already set to what you want to change it to, that variable will be skipped over; it would be unnecessary to reset. - if use_update is true, UPDATEs will be used instead of REPLACE. - when use_update is true, the value can be true or false to increment or decrement it, respectively. string constructPageIndex(string base_url, int &start, int max_value, int num_per_page, bool compact_start = false) - builds the page list, e.g. 1 ... 6 7 [8] 9 10 ... 15. - compact_start caused it to use "url.page" instead of "url;start=page". - handles any wireless settings (adding special things to URLs.) - very importantly, cleans up the start value passed, and forces it to be a multiple of num_per_page. - also checks that start is not more than max_value. - base_url should be the URL without any start parameter on it. - uses the compactTopicPagesEnable and compactTopicPagesContiguous settings to decide how to display the menu. - an example is available near the function definition. string comma_format(float number) - formats a number to display in the style of the admins' choosing. - uses the format of number_format to decide how to format the number. - for example, it might display "1 234,50". - caches the formatting data from the setting for optimization. string timeformat(int time, bool show_today = true, string offset_type = false) - returns a pretty formated version of time based on the user's format in $user_info['time_format']. - applies all necessary time offsets to the timestamp, unless offset_type is set. - if todayMod is set and show_today was not not specified or true, an alternate format string is used to show the date with something to show it is "today" or "yesterday". - performs localization (more than just strftime would do alone.) string un_htmlspecialchars(string text) - removes the base entities (&lt;, &quot;, etc.) from text. - should be used instead of html_entity_decode for PHP version compatibility reasons. - additionally converts &nbsp; and &#039;. - returns the string without entities. string shorten_subject(string regular_subject, int length) - shortens a subject so that it is either shorter than length, or that length plus an ellipsis. - respects internationalization characters and entities as one character. - avoids trailing entities. - returns the shortened string. int forum_time(bool use_user_offset = true) - returns the current time with offsets. - always applies the offset in the time_offset setting. - if use_user_offset is true, applies the user's offset as well. - returns seconds since the unix epoch. array permute(array input) - calculates all the possible permutations (orders) of array. - should not be called on huge arrays (bigger than like 10 elements.) - returns an array containing each permutation. string parse_bbc(string message, bool smileys = true, string cache_id = '', array parse_tags = null) - this very hefty function parses bbc in message. - only parses bbc tags which are not disabled in disabledBBC. - also handles basic HTML, if enablePostHTML is on. - caches the from/to replace regular expressions so as not to reload them every time a string is parsed. - only parses smileys if smileys is true. - does nothing if the enableBBC setting is off. - applies the fixLongWords magic if the setting is set to on. - uses the cache_id as a unique identifier to facilitate any caching it may do. - returns the modified message. void parsesmileys(string &message) - the smiley parsing function which makes pretty faces appear :). - if custom smiley sets are turned off by smiley_enable, the default set of smileys will be used. - these are specifically not parsed in code tags [url=mailto:Dad@blah.com] - caches the smileys from the database or array in memory. - doesn't return anything, but rather modifies message directly. string highlight_php_code(string code) - Uses PHP's highlight_string() to highlight PHP syntax - does special handling to keep the tabs in the code available. - used to parse PHP code from inside [code] and [php] tags. - returns the code with highlighted HTML. void writeLog(bool force = false) // !!! void redirectexit(string setLocation = '', bool use_refresh = false) // !!! void obExit(bool do_header = true, bool do_footer = do_header) // !!! int logAction($action, $extra = array()) // !!! void trackStats($stats = array()) - caches statistics changes, and flushes them if you pass nothing. - if '+' is used as a value, it will be incremented. - does not actually commit the changes until the end of the page view. - depends on the trackStats setting. void spamProtection(string error_type) - attempts to protect from spammed messages and the like. - takes a $txt index. (not an actual string.) - time taken depends on error_type - generally uses the modSetting. array url_image_size(string url) - uses getimagesize() to determine the size of a file. - attempts to connect to the server first so it won't time out. - returns false on failure, otherwise the output of getimagesize(). void determineTopicClass(array &topic_context) // !!! void setupThemeContext(bool force_reload = false) // !!! void template_rawdata() // !!! void template_header() // !!! void theme_copyright(bool get_it = false) // !!! void template_footer() // !!! void db_debug_junk() // !!! void getAttachmentFilename(string filename, int id_attach, bool new = true) // !!! array ip2range(string $fullip) - converts a given IP string to an array. - internal function used to convert a user-readable format to a format suitable for the database. - returns 'unknown' if the ip in the input was '255.255.255.255'. string host_fro
