sql - php to return id using Scope_identity -

searching other articles have come conclusion need use scope_identity() return value of primary key gets generated when insert row ms sql table. not clear me php need return value. being new, have gotten away until borrowing code predecessor run sql queries, have been situations returning results array using while loop. please advise correct code.

$query = "insert mytable (title,author)           values('".sql_safe($title)."', '"sql_safe($author)."'); select scope_identity() myid;";  $result = odbc_exec($con1, $query); 

until have ever needed use

while($row = odbc_fetch_array($result)){ } 

but correct way of referring myid ?

$query ="        insert powerview.dl_documentlist (title,liveversion,author,location,locked,lockedbyid)                 values('".sql_safe($title)."',1.0,'".sql_safe($author)."','".sql_safe($location)."','1',".$lockedbyid.");                  select scope_identity() id;                 return;              ";      $result = mssql_query($query);           $result = mssql_fetch_object($result);      $docid = $result->id;
