[Database class] checking values going into db

[Paul S. Wang]

Dear DB class,

Please note that it is important when inserting and updating
tables that the values going into the DB are correct.
This is especially true if the values are strings from command-line
input (or web form input).

For example if you enter a -2 or a "FOO" string into a qty field,
you would be very sorry.

Here are some PHP functions that can help:

<?php
$str = '232.98 The';
echo floatval($str);   // 232.98
echo "\n";
echo intval($str);     // 232
?>

Paul
