I am relatively new to OOP in general so this question may sound dumb but
In this documentation: Query Performance and Prefetching
To quote that text, "
The $db->setPrefetch() call is used to set the prefetch value. The microtime() calls are used to show how long the report took to generate.
A new Db::fetchRow() method is used to get one row at a time. It is called in a loop after the query has been run"
Why the does it use the scope resolution operator? Isn't it used for just static methods and overridden methods.
I do not see any static declaration when this method is entered into class.
To quote the method declaration:
/** * Fetch a row of data. Call this in a loop after calling Db::execute() * * @return array An array of data for one row of the query */
public function fetchRow() {
$row = oci_fetch_array($this->stid, OCI_ASSOC + OCI_RETURN_NULLS);
return($row);
}
Am I missing something really trivial thing about this concept?
Thank you.
