更新後にこの問題に直面していますdatabase.phpファイルはDBユーザーとパスワードのみを更新します。対面機能mysqli_init mysqliドライバが既にインストールされているのに対し、致命的なエラー

私は、これは同じ問題と重複して質問です知っているソリューション

Codeigniter: fatal error call to undefined function mysqli_init()

については、以下の答えを経ていその後

| DATABASE CONNECTIVITY SETTINGS 
| ------------------------------------------------------------------- 
| This file will contain the settings needed to access your database. 
| 
| For complete instructions please consult the 'Database Connection' 
| page of the User Guide. 
| 
| ------------------------------------------------------------------- 
| EXPLANATION OF VARIABLES 
| ------------------------------------------------------------------- 
| 
| ['dsn']  The full DSN string describe a connection to the database. 
| ['hostname'] The hostname of your database server. 
| ['username'] The username used to connect to the database 
| ['password'] The password used to connect to the database 
| ['database'] The name of the database you want to connect to 
| ['dbdriver'] The database driver. e.g.: mysqli. 
|   Currently supported: 
|    cubrid, ibase, mssql, mysql, mysqli, oci8, 
|    odbc, pdo, postgre, sqlite, sqlite3, sqlsrv 
| ['dbprefix'] You can add an optional prefix, which will be added 
|    to the table name when using the Query Builder class 
| ['pconnect'] TRUE/FALSE - Whether to use a persistent connection 
| ['db_debug'] TRUE/FALSE - Whether database errors should be displayed. 
| ['cache_on'] TRUE/FALSE - Enables/disables query caching 
| ['cachedir'] The path to the folder where cache files should be stored 
| ['char_set'] The character set used in communicating with the database 
| ['dbcollat'] The character collation used in communicating with the database 
|    NOTE: For MySQL and MySQLi databases, this setting is only used 
|    as a backup if your server is running PHP < 5.2.3 or MySQL < 5.0.7 
|    (and in table creation queries made with DB Forge). 
|    There is an incompatibility in PHP with mysql_real_escape_string() which 
|    can make your site vulnerable to SQL injection if you are using a 
|    multi-byte character set and are running versions lower than these. 
|    Sites using Latin-1 or UTF-8 database character set and collation are unaffected. 
| ['swap_pre'] A default table prefix that should be swapped with the dbprefix 
| ['encrypt'] Whether or not to use an encrypted connection. 
| 
|   'mysql' (deprecated), 'sqlsrv' and 'pdo/sqlsrv' drivers accept TRUE/FALSE 
|   'mysqli' and 'pdo/mysql' drivers accept an array with the following options: 
| 
|    'ssl_key' - Path to the private key file 
|    'ssl_cert' - Path to the public key certificate file 
|    'ssl_ca'  - Path to the certificate authority file 
|    'ssl_capath' - Path to a directory containing trusted CA certificats in PEM format 
|    'ssl_cipher' - List of *allowed* ciphers to be used for the encryption, separated by colons (':') 
|    'ssl_verify' - TRUE/FALSE; Whether verify the server certificate or not ('mysqli' only) 
| 
| ['compress'] Whether or not to use client compression (MySQL only) 
| ['stricton'] TRUE/FALSE - forces 'Strict Mode' connections 
|       - good for ensuring strict SQL while developing 
| ['ssl_options'] Used to set various SSL options that can be used when making SSL connections. 
| ['failover'] array - A array with 0 or more data for connections if the main should fail. 
| ['save_queries'] TRUE/FALSE - Whether to "save" all executed queries. 
|    NOTE: Disabling this will also effectively disable both 
|    $this->db->last_query() and profiling of DB queries. 
|    When you run a query, with this setting set to TRUE (default), 
|    CodeIgniter will store the SQL statement for debugging purposes. 
|    However, this may cause high memory usage, especially if you run 
|    a lot of SQL queries ... disable this to avoid that problem. 
| 
| The $active_group variable lets you choose which connection group to 
| make active. By default there is only one group (the 'default' group). 
| 
| The $query_builder variables lets you determine whether or not to load 
| the query builder class. 
*/
