Problem extracting values from mysql

[system]

I have included this snippet from my class. The method getAllReelTest() selects products with a specific category number from a MYSQL db.

This is the function stored in (reelClass) class. The class has various static variables ie table1, table2, table3 etc
[php]
reelClass{
static $table3 =‘itm_details’;

public function getAllReelTest($category){
$sql = “SELECT * FROM '”.self::$table3 ."’
WHERE itm_cat = ‘" . $category . "’
ORDER
BY id
ASC";

		$stmt = mysqli_query($this->connection,$sql);
	        while($result = mysqli_fetch_array($this->connection,$stmt))
                   {
		print_r($result);
		}

}
[/php]

code to instantiate the class and call the method
[php]
$reel = new reelClass();
$reel->getAllReelTest(2)
[/php]

The error I am getting is as follows.
mysqli_fetch_array() expects parameter 1 to be mysqli_result, object given
I think this is probably because i have written my sql wrong in some way. Please can someone help?

Change:
[php]while($result = mysqli_fetch_array($this->connection,$stmt))[/php]

to:
[php]while($result = mysqli_fetch_array($stmt))[/php]
