<?php

//assume you have these set somewhere

$sqlcall = new SQLCall($db_user, $db_password, $db_host, $db_name);

//"true" as a parameter to this method will print out the error message
//if any exists. Method returns true or false so can be used in conditionals.
$sqlcall->hadErrors(true);

//set up a select statement to show off the goods
$sqlcall->doSelect("SELECT id, member_id AS mid FROM visitors", false);

"This select retrieved " . $sqlcall->getFieldCount() . " columns per row.<BR>";

while(

//The beauty of simplicity - the object sets member variables corresponding
  //to the names of each of the columns in the result set, so that you can
  //simply do $sqlcall-><column name> to access the result. Notice how
  //aliases are handled seamlessly
 
print "ID: $sqlcall->id, Member ID: $sqlcall->mid<BR>";

 
//all results are also available as $sqlcall->f<n> where n is a 1-based
  //index. This is good for generic processing.
 
print "Alternative (should be the same output): ID: $sqlcall->f1, Member ID: $sqlcall->f2<BR>";

//while

//There is no column "x" in this table - expect an error here.
//The error is written into a comment in the source HTML.
