MysqlndUhConnection::init — Initialize mysqlnd connection
说明
public MysqlndUhConnection::init ( mysqlnd_connection$connection
) : bool
Initialize mysqlnd connection. This is an mysqlnd internal call to initialize the connection object.
Note:
Failing to call the parent implementation may cause memory leaks or crash PHP. This is not considered a bug. Please, keep in mind that the mysqlnd library functions have never been designed to be exposed to the user space.

Otherwise, returns FALSE
范例
Example #1 MysqlndUhConnection::init() example
<?php
class proxy extends MysqlndUhConnection {
public function init($res) {
printf("%s(%s)\n", __METHOD__, var_export(func_get_args(), true));
$ret = parent::init($res);
printf("%s returns %s\n", __METHOD__, var_export($ret, true));
return $ret;
}
}
mysqlnd_uh_set_connection_proxy(new proxy());
$mysqli = new mysqli("localhost", "root", "", "test");
?>
以上例程会输出：
proxy::init(array ( 0 => NULL, )) proxy::init returns true
