I needed a list of transactions in CSV format for a given Bitcoin or Namecoin address, but I couldn't find anything that would directly give me the list (especially in the format I wanted), so I cooked up some code.
Requirements (or at least what is known good without code modification):
I made one PHP file and a SQL function for the bitcoin-abe database based on the SQL in the bitcoin-abe python code.
txs.php:
<?php
include 'bitcoin.inc';
$addr = $_GET['address'];
// Can't do the following because Namecoin addresses will fail this
// if (Bitcoin::checkAddress($addr) == false) exit("ERROR: Not a valid address.");
exec("sudo -u nope /path/cgi-bin/abe");
$dbconn = pg_connect("host=nope dbname=nope user=nope password=nope");
$params = array(Bitcoin::addressToHash160($addr));
$result = pg_query_params($dbconn, "SELECT * FROM GetTransactions($1)", $params);
$arr = pg_fetch_all($result);
pg_close($dbconn);
if ($arr) {
$out = fopen('php://output', 'w');
fputcsv($out, array_keys($arr[0]));
for ($i = 0; $i < count($arr); $i++) {
fputcsv($out, $arr[$i]);
}
fclose($out);
} else {
echo("ERROR: No results.");
}
?>
GetTransactions.sql:

EDIT: Added command to txs.php for updating the abe database before returning data and example output.
