I find that my IDE catches most of the typos before I even try to run the page.
I use Netbeans 6.5 with the PHP extension, but there are alternatives...

Generally it's not worth the trouble, but you could cache in the session...
Remember that PHP is largely stateless, so one page call knows nothing of any
other page calls. This is different to Java, where you can hold state in the
underlying virtual machine and recover it later...

With PostgreSQL (and probably MySQL too) you can do either a prepared statement
(see http://www.php.net/manual/en/function.pg-prepare.php) and then execute
that, or a simpler parameterised query (see
Something like

$sql = 'SELECT * FROM user WHERE username=$1';
$params = Array('pete');
$result = pg_query_params($sql,$params);

That way you get the safest handling of values without any tedious messing about
with manually escaping strings.
I suspect that under the hood it actually prepares a statement and then executes
it, but I might be wrong...
