note 40806 added to function.defined

defined() is exceptionally useful when building an online application. With the defined() function you can create application wide CONSTANTS and then with a simple require_once line you can bring these CONSTANTS into your application. Example: <?php // Database connectivity - start define("DBNAME", "enter_database_name" ); define("DBUSERNAME", "enter_dbuser_name" ); define("DBPASSWORD", "enter_dbpassword" ); define("DBSERVERHOST", "localhost" ); // Database connectivity - end // URL, email and organization details - start define("INSTALL_URL", "http://localhost/yourdomain.com/"); define("WEBMASTER", "info@NOSPAMyourdomain.com" ); define("SYSTEMEMAIL", "no-reply@NOSPAMyourdomain.com" ); define("ORGANIZATION", "Your Organization" ); define("ADMINHOME", "admin.php"); define("ADMINUSER", "admin"); define("ADMINPASSWORD", "admin"); define("LEGALNAME", "Your Legal Name"); define("PRODUCTNAME", "Your Application Name"); define("INSTALLVERSION", "1.1"); // URL, email and organization details - end /* save this file as secret.php and then bring these CONSTANTS into your application using the form: */ require_once("secret.php"); /*This makes changing the database name a snap - if used in the invoking pconnect(): // pconnect, select and query */ if ($link_identifier = mysql_pconnect(DBSERVERHOST, DBUSERNAME, DBPASSWORD)) { if ( mysql_select_db(DBNAME, $link_identifier)) { // your $query and processing here ) /* I also use it to declare database table names, so the user can easily customize their implementation. */ ?> ---- Manual Page -- http://www.php.net/manual/en/function.defined.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+40806 Delete -- http://master.php.net/manage/user-notes.php?action=delete+40806&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+40806&report=yes Search -- http://master.php.net/manage/user-notes.php
