Description:
------------
I am executing a loop of 4 statements: 2 INSERTS returning insert IDs and 2 SELECTS.  The last 2 SELECTS both show insert IDs equal to the value of the last successful INSERT.  I believe the appropriate behavior should be that mysqli_insert_id return a value of zero or null for the SELECTs.

Reproduce code:
---------------
<?php
$server='localhost';
$user='parkdomains';
$pass='$p@rkpl@ce$';
$database='ParkDomains';

###CONNECT TO DATABASE
$dbconn=mysqli_init();
mysqli_options($dbconn,MYSQLI_OPT_CONNECT_TIMEOUT,8);
//mysqli_real_connect($dbconn,$server,$user,$pass,$database,null,null,MYSQLI_CLIENT_FOUND_ROWS);
mysqli_real_connect($dbconn,$server,$user,$pass,$database,null,null,MYSQLI_CLIENT_FOUND_ROWS);
if(mysqli_connect_errno()){
	printf("Can't connect to the MySQL Server (".$server."): %s\n", mysqli_connect_error()); 
}
@mysqli_select_db($dbconn,$database);
if(mysqli_error($dbconn)) $ReportError(sprintf("Can't select the MYSQL database (".$database."): %s\n", mysqli_error($dbconn)),1);


###OUR SQL STATEMENTS###
$sql_statements_statements=array();
$sql_statements[]="INSERT INTO test () VALUES('','test')";
$sql_statements[]="INSERT INTO test () VALUES('','test')";
$sql_statements[]="SELECT * FROM test LIMIT 3";
$sql_statements[]="SELECT * FROM test LIMIT 2";

###COMBINE THEM INTO ONE###
$query=implode(';',$sql_statements);
echo $query."<BR>\n";

$ret=array();
reset($sql_statements);
if(mysqli_multi_query($dbconn,$query)){
	do{
		$obj=new stdClass();
		list(,$obj->sql)=each($sql_statements);
		$res=mysqli_store_result($dbconn);
		$obj->affected_rows=mysqli_affected_rows($dbconn);
		$obj->last_insert_id=mysqli_insert_id($dbconn);
		if($res){
			if(mysqli_num_rows($res)>0){
				while ($row=mysqli_fetch_row($res)){
					$obj->result[]=$row;
				};
				mysqli_free_result($res);
			}
		}
		$ret[]=$obj;
	}while(mysqli_next_result($dbconn));
}
echo "<pre>";
print_r($ret);
?>

----------------
