It's commonly seen in OOP (Object Oriented Programming)
and allows you access to an objects data by name of the
entity within the structure.
I find it really useful for mysql/php work.
$result = mysql_query("SELECT * From Personal_Details WHERE
USER_ID='12345'") ;
$data = mysql_fetch_object($result) ;
print "My name: " . $data->full_name . " and email are : " .
$data->email_addr . "<BR>" ;
And full_name and email_addr are field names in the
database table... so you don't need to worry about $data[0] being the
field
you expect it to be should you go an change the table layout with ALTER
TABLE.
