PHP database connection class

Question

I am trying to get a users ID from a database within a class, but I have very little to no experience with classes, how could I go about getting the uid from the DB and then

Answer 1

There is a problem with the way your code is written, not with the class. Take a closer look at this line:

$array = mysql_fetch_array($result);

This is the first time variable $result appears on the function. Therefore, it is not possible to communicate with the database.

A possible pseudo-code would be:

• connect to the DB server
• query the database
• fetch the results
• return the uid field.

Have a look at the relevant documentation first:

• http://php.net/manual/en/function.mysql-connect.php
• http://www.php.net/manual/en/function.mysql-query.php
• http://www.php.net/manual/en/function.mysql-fetch-array.php
