I'm working on a personal project to get used to PHP, and I seem to be
stuck at the moment on a class I'm writing. Here is the code for the
class, with a comment highlighting where it dies when a function is
called externally from the code that instantiates the class:

$rowCount = $resultSet->num_rows;
if ($rowCount 0)
{
$i = 0;
while ($i < $rowCount)
{
$rows[$i] = $resultSet->fetch_assoc();
$i++;
}
$resultSet->free();
return $rows;
}

// TODO: report an empty set
$resultSet->free();

$resultSet->free();
return;

The error log seems to be claiming that $databaseConnection is
undefined on that line of code. Is there maybe something syntactic
that I'm missing? I've tried replacing all 3 references to
$databaseConnection in the class functions with
$this->$databaseConnection, but that didn't seem to change anything.

the way you did it in constructor the variable databaseConnection has
scope only in that particular method, you should use
@ $this->databaseConnection = new mysqli("this", "is", "fake", "data");
and allways reference that property via $this->databaseConnecion...
you were using local variables where you really needed class properties
