here's the function (taken off the website he quoted):
<?php
function prepareSQL($queryString, $paramArr) {
foreach (array_keys($paramArr) as $paramName) {
if (is_int($paramArr[$paramName])) {
$paramArr[$paramName] = (int)$paramArr[$paramName];
}
elseif (is_numeric($paramArr[$paramName])) {
$paramArr[$paramName] = (float)$paramArr[$paramName];
}
elseif (($paramArr[$paramName] != 'NULL') and
($paramArr[$paramName] != 'NOT NULL')) {
$paramArr[$paramName] =
mysql_real_escape_string(stripslashes($paramArr[$paramName]));
$paramArr[$paramName] = '\''.$paramArr[$paramName].'\'';
}
}
return preg_replace('/\{(.*?)\}/ei','$paramArr[\'$1\']', $queryString);
}
