ENTITY

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
The maximum number of persistent connections that can be made. Set to 0 for unlimited.

mysqli.max_links int
The maximum number of 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.

[!NOTE] This ENTITY 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.
