Question

I have this method in my db class

public function query($queryString)     {        if (!$this->_connected) $this->_connectToDb(); //connect to database        $results = mysql_query($queryString, $this->_dbLink) or trigger_error(mysql_error());        return mysql_num_rows($results) > 0 ? mysql_fetch_assoc($results) : false;                  } 

This works great for queries that return 1 row, but how can I get an array returned something like this?

$array[0]['name'] = 'jim' $array[0]['id'] =  120 $array[1]['name'] = 'judith'  $array[1]['ID'] = 121 

Now I know I could use a while loop to insert this data into the array like so, but I was wondering if PHP could do this with an internal function? I havn’t been able to find on the docs what I’m after.

The reason I don’t want to run the while within the method is because I am going to reiterate back over the array when it’s returned, and I’d rather not run through the results twice (for performance reasons).

Is there a way to do this? Do I have a problem with my general query method design?

Thank you muchly!

public function query($queryString)     {          if (!$this->_connected) $this->_connectToDb(); //connect to database          $results = mysql_query($queryString, $this->_dbLink) or trigger_error(mysql_error());          $data = array();         while($row = mysql_fetch_assoc($results))          {                $data[] = $row;          }         return $data;      } 

this will always return an array.

EDIT: I didn’t read the question well. If you realy don’t want to use the loop then I would do this:

public function query($queryString)     {          if (!$this->_connected) $this->_connectToDb(); //connect to database          return mysql_query($queryString, $this->_dbLink) or trigger_error(mysql_error());      } 

then loop over it, however I would just use the loop.
