I need to write a method to return the number of rows I have in my table. This code I've written so far;

<pre><?php  
     class Database
{
	
	private $connected=false;
	private $user,$pass,$host;
	private $db;
	private $result=array();
	
	public function initialize($user, $pass, $host)
	{
	 $this->user=$user;
	 $this->pass=$pass;
	 $this->host=$host;
	 return $this;
		
    }
	
  function connect($dbname)
  
  {
   $this->db=mysql_connect($this->host,$this->user,$this->pass) or
   die('<h1>Unable to connect to database</h1>' . mysql_error()); 
   mysql_select_db($dbname) or die('<h1>Unable to select database</h1>' . mysql_error());
   return $this;
  }
  
  function query($sqlstring)
  {
	$query= mysql_query($sqlstring,$this->db) or die('<h1>Unable to query database</h1>' . mysql_error());  
	while($record=mysql_fetch_assoc($query)){
		$this->result[]=$record;
	}
	return $this->result;
  }

  /*function numRows($sq)
  {
    $this->$query="select count(*) as numRows from members";
  }*/

}

$db = new Database();
print_r($db->initialize("root","project","localhost")->connect("mmsplus")->
        query("SELECT count(*) as num FROM members"));

?></pre>

So far this does the work but I need a separate method for the counting, any help is appreciated.

The option I would choose is a property last_count. Before the return in your query function you could do

$this->last_count = count($this->result);

Side note: At this point the query function does not reset your result property. Should you execute two queries after one another, result would contain both.

Use count function on result set. It will give you the total number of records.

$query= mysql_query($sqlstring,$this->db) or die('<h1>Unable to query database</h1>' . mysql_error());
echo mysql_num_rows($query);

mysql_num_rows is return the number of records in your table

Thanks folks, I managed to get what I wanted. Below is the full code:

<pre><?php  
     class Database
{
	
	private $connected=false;
	private $user,$pass,$host;
	private $db;
	private $result=array();
        
	
	public function initialize($user, $pass, $host)
	{
	 $this->user=$user;
	 $this->pass=$pass;
	 $this->host=$host;
	 return $this;
		
    }
	
  function connect ($dbname)
  
  {
   $this->db=mysql_connect($this->host,$this->user,$this->pass) or
   die('<h1>Unable to connect to database</h1>' . mysql_error()); 
   mysql_select_db($dbname) or die('<h1>Unable to select database</h1>' . mysql_error());
   return $this;
  }
  
  function query ($sqlstring)
  {     $this->result = array(); //resets the array anytime a query is run
	$query= mysql_query($sqlstring,$this->db) or die('<h1>Unable to query database</h1>' . mysql_error());  
	while($record=mysql_fetch_assoc($query)){
		$this->result[]=$record;
	}
       // echo mysql_num_rows($query) . "<br />";// counts the total number of rows
	return $this->result;
  }
// An alternative to display numRows is to write a method

    function numRows($table)
    {
        $result = $this->query("select count(*) as totalRows from $table");
         return $result[0]['totalRows'];// it will start counting from the first array in the table
    }

  
}

$db = new Database();
print_r($db->initialize("root","project","localhost")->connect("mmsplus")->
        query("SELECT * FROM members"));
echo $db->numRows('members');
