Bug description: mysqli_insert_id with mysqli_multi_query returns wrong value
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);
?>
Expected result:
----------------
INSERT INTO test () VALUES('','test');INSERT INTO test ()
VALUES('','test');SELECT * FROM test LIMIT 3;SELECT * FROM test LIMIT 2
