ArchivesPHP MySQL Database Class
April 19th, 2005A class for very basic MySQL database connectivity. Written to reduce redundant code in my own projects aswell as aid in debugging and error reporting during the developement phase. Currently connects to a database, execute external files containing SQL commands, insert and update from an array of key => value pairs, insert and update with sql command, query (one result), query (multiple rows), and dump a select query to a table. The zip file contains the class aswell as a demonstration script.

Hi,
Your script is working for me but I can't find which database was used to create the table users in ! I'm new to MySQL. Could you help me out with this?

Hi,
The script works perfectly fine on my PC, but online I get a "no database selected" error. I think it has something to do with the MySQL version of the server being quite old (3.23).
Could you tell me what I should change within the script?

Are you sure you typed the database name correctly? Are you sure there is a database setup online?

Good job, a nice handy class, i will use it on my scripts.
I found kind of bug, at select, when query fails, row_count remains the same, i think it`s better to set it to 0 ;
if (!$r) {
$this->last_error = mysql_error();
$this->row_count = 0;
return false;
}

Very nice class.
I would suggest that you consider developing another flavour that uses MySqli.
As for this one, there is just one missing thing in it, ESCAPING strings. You can add a public function that can be used to escape values before being put into a query.

The same error as Diego had:

$data = array(
'id' => '',
'timestamp' => '',
'txn_id' => 'ok',
'verify_sign' => 'verified',
);
$id = $db->insert_array('ipns', $data);
if (!$user_id) $db->print_last_error(false);
$db->print_last_query();
$db->dump_query("SELECT * FROM ipns WHERE id=$id");
produces the insert SQL of:
INSERT INTO ipns (id,timestamp,txn_id,verify_sign) VALUES (,,'ok','verified')
wheras it needs to be:
INSERT INTO ipns (id,timestamp,txn_id,verify_sign) VALUES ('','','ok','verified')
for the cases where the variable is set, but has no value.
