MysqlndUhConnection::stmtInit — Initializes a statement and returns a resource for use with mysqli_statement::prepare

说明

public resource MysqlndUhConnection::stmtInit ( mysqlnd_connection $connection )

Initializes a statement and returns a resource for use with mysqli_statement::prepare.

Resource of type Mysqlnd Prepared Statement (internal only - you must not modify it!). The documentation may also refer to such resources using the alias name mysqlnd_prepared_statement.

范例

Example #1 MysqlndUhConnection::stmtInit() example

  <?php
 class  proxy  extends  MysqlndUhConnection  {
 public function  stmtInit ( $res ) {
   printf ( "%s(%s)\n" ,  __METHOD__ ,  var_export ( func_get_args (),  true ));
   var_dump ( $res );
   $ret  =  parent :: stmtInit ( $res );
   printf ( "%s returns %s\n" ,  __METHOD__ ,  var_export ( $ret ,  true ));
   var_dump ( $ret );
  return  $ret ;
 }
}
 mysqlnd_uh_set_connection_proxy (new  proxy ());
 $mysqli  = new  mysqli ( "localhost" ,  "root" ,  "" ,  "test" );
 $stmt  =  $mysqli -> prepare ( "SELECT 1 AS _one FROM DUAL" );
 $stmt -> execute ();
 $one  =  NULL ;
 $stmt -> bind_result ( $one );
 $stmt -> fetch ();
 var_dump ( $one );
 ?>

以上例程会输出：

proxy::stmtInit(array (
  0 => NULL,
))
resource(19) of type (Mysqlnd Connection)
proxy::stmtInit returns NULL
resource(246) of type (Mysqlnd Prepared Statement (internal only - you must not modify it!))
int(1)
