Notes
PerformanceSpeed-wise, the function is identical to mysql_fetch_array
, and almost as quick as mysql_fetch_row
(the difference is insignificant).Note
mysql-fetch-object
is similar to mysql_fetch_array
, with one difference - an object is returned, instead of an array. Indirectly, that means that you can only access the data by the field names, and not by their offsets (numbers are illegal property names).Note
Field names returned by this function are case-sensitive.Note
This function sets NULL fields to the PHP NULL
value.
