sqlsrv_fetch_array() expects parameter 1 to be resource, object given - sql-server

Question

Good Day,
I was looking for the solution of this code. But unfortunately I couldn`t fix it hope someone can enlighten me on this matter.
function getCharactersBySerial($serial)
{
$charinfo = "";
$i = 0;
$CI =& get_instance();
$CI->mssql = $CI->load->database( 'world', TRUE );
$char_result = $CI->mssql->query("SELECT * FROM RF_World.dbo.tbl_base WHERE Serial= $serial and DCK='0'");
while ($character = sqlsrv_fetch_array($char_result))
{
$charinfo['Serial'] = $character['Serial'];
$charinfo['Name'] = $character['Name'];
$charinfo['AccountSerial'] = $character['AccountSerial'];
$i = 1;
return $charinfo;
}
if ($i == 0 ) {
return "None";
}
}
and this is the other one they have both same errors
function getCharactersGuildBySerial($serial)
{
$charinfo = "";
$i = 0;
$CI =& get_instance();
$CI->mssql = $CI->load->database( 'world', TRUE );
$char_result = $CI->mssql->query("SELECT B.Name, L.id FROM tbl_base as B INNER JOIN tbl_general as G ON G.Serial = B.Serial INNER JOIN tbl_Guild as L ON L.Serial = G.GuildSerial WHERE B.Serial= $serial and B.DCK='0'");
while ($character = sqlsrv_fetch_array($char_result))
{
$charinfo['GuildName'] = $character['id'];
$charinfo['Name'] = $character['Name'];
$i = 1;
return $charinfo;
}
if ($i == 0 ) {
$charinfo['Name'] = 'None';
return $charinfo;
}
}

I just fund out the error was because of my Condition and it only appears if the query doesn`t have a result. Please check below for the fix that I did:
function getCharactersBySerial($serial)
{
$charinfo = "";
$i = 0;
$CI =& get_instance();
$CI->mssql = $CI->load->database( 'world', TRUE );
$char_result = $CI->mssql->query("SELECT * FROM RF_World.dbo.tbl_base WHERE Serial= $serial and DCK='0'");
if($char_result->num_rows()<=0){
return 'None';
}else{
while ($character = sqlsrv_fetch_array($char_result))
{
$charinfo['Serial'] = $character['Serial'];
$charinfo['Name'] = $character['Name'];
$charinfo['AccountSerial'] = $character['AccountSerial'];
$i = 1;
return $charinfo;
}
}
}
and
function getCharactersGuildBySerial($serial)
{
$charinfo = "";
$i = 0;
$CI =& get_instance();
$CI->mssql = $CI->load->database( 'world', TRUE );
$char_result = $CI->mssql->query("SELECT B.Name, L.id FROM tbl_base as B INNER JOIN tbl_general as G ON G.Serial = B.Serial INNER JOIN tbl_Guild as L ON L.Serial = G.GuildSerial WHERE B.Serial= $serial and B.DCK='0'");
if($char_result->num_rows()<=0){
$charinfo['Name'] = 'None';
return $charinfo;
}else{
while ($character = sqlsrv_fetch_array($char_result))
{
$charinfo['GuildName'] = $character['id'];
$charinfo['Name'] = $character['Name'];
$i = 1;
return $charinfo;
}
}
}
