Yapılandırma yönergelerinin kısa açıklamalarını aşağıda bulabilirsiniz.
mysqli.allow_local_infile
    bool
   Allow accessing, from PHP's perspective, local files with LOAD DATA statements
mysqli.local_infile_directory
    string
   Allows restricting LOCAL DATA loading to files located in this designated directory.
mysqli.allow_persistent
    bool
   Enable the ability to create persistent connections using mysqli_connect().
mysqli.max_persistent
    int
   Maximum of persistent connections that can be made. Set to 0 for unlimited.
mysqli.max_links
    int
   The maximum number of MySQL connections per process.
mysqli.default_port
    int
   
     The default TCP port number to use when connecting to
     the database server if no other port is specified. If
     no default is specified, the port will be obtained
     from the MYSQL_TCP_PORT environment
     variable, the mysql-tcp entry in
     /etc/services or the compile-time
     MYSQL_PORT constant, in that order. Win32
     will only use the MYSQL_PORT constant.
    
mysqli.default_socket
    string
   The default socket name to use when connecting to a local database server if no other socket name is specified.
mysqli.default_host
    string
   The default server host to use when connecting to the database server if no other host is specified.
mysqli.default_user
    string
   The default user name to use when connecting to the database server if no other name is specified.
mysqli.default_pw
    string
   The default password to use when connecting to the database server if no other password is specified.
mysqli.reconnect
    int
   Automatically reconnect if the connection was lost.
Bilginize: This php.ini setting had been ignored by the mysqlnd driver, and was removed as of PHP 8.2.0.
mysqli.rollback_on_cached_plink
    bool
   If this option is enabled, closing a persistent connection will rollback any pending transactions of this connection before it is put back into the persistent connection pool. Otherwise, pending transactions will be rolled back only when the connection is reused, or when it is actually closed.
   Users cannot set MYSQL_OPT_READ_TIMEOUT through an API 
   call or runtime configuration setting. Note that if it were possible there
   would be differences between how libmysqlclient and 
   streams would interpret the value of MYSQL_OPT_READ_TIMEOUT.
