You'll need to switch to ``smiley_js()`` instead. +Database drivers 'mysql', 'sqlite', 'mssql', 'pdo/dblib' +======================================================== + +The **mysql** driver utilizes the old 'mysql' PHP extension, known for its aging code base and +many low-level problems. The extension is deprecated as of PHP 5.5 and CodeIgniter deprecates +it in version 3.0, switching the default configured MySQL driver to **mysqli**. + +Please use either the 'mysqli' or 'pdo/mysql' drivers for MySQL. The old 'mysql' driver will be +removed at some point in the future. + +The **sqlite**, **mssql** and **pdo/dblib** (also known as pdo/mssql or pdo/sybase) drivers +all depend on PHP extensions that for different reasons no longer exist since PHP 5.3. + +Therefore we are now deprecating these drivers as we will have to remove them in one of the next +CodeIgniter versions. You should use the more advanced, **sqlite3**, **sqlsrv** or **pdo/sqlsrv** +drivers respectively. + +.. note:: These drivers are still available, but you're strongly encouraged to switch to other ones + sooner rather than later. + Security helper do_hash() ========================= |
