<?php
// initialize array
$vals = array();
// Fetch data from database, put them into associative array
//
// I am assuming the SQL will be something like:
// SELECT comparableValue, otherInformation1, otherInformation2 FROM
sometable
//
// Thus. when fetching result:
// $temp[0] = comparableValue
// $temp[1] = otherInformation1
// $temp[2] = otherInformation2
//
// With associative array, the newer values will always
// re-write the older value. See example
//
// Say you fecth the row, it returned array('value1', 'someinfo',
'someinfo')
// I will put them into assoc array, where 'value1' will be the key.
// The next fetch, it returns array('value1', 'someinfoagain',
'someinfotoo')
// If I put them into the same associative array, with the same key,
// it will over-write the previous value.
// and so on.
//
// Try first. If still don't understand. please ask again in ng
//
// PS. for Craig. 2 pass loop is not an elegant solution. But it's just
an advice
//
while ($temp = fetch_row_from_db()) $vals[$temp[0]] = $temp;
// This just dump the whole array to screen
var_dump($vals);
