Solution 1

See here: PHP: PDO::prepare - Manual[^]

Quote:
Return Values
If the database server successfully prepares the statement, PDO::prepare() returns a PDOStatement object. If the database server cannot successfully prepare the statement, PDO::prepare() returns false or emits PDOException (depending on error handling).

So for some reason prepare is returning false
And the reason why is probably that dot...

SQL

status FROM ".$this->foodItemsTable)

Thank you.. After removing the (dot) I still get another error (syntax error , unexpected $this (T_VARIABLE),expecting')' in line 12)

By looking at the documentation for PHP, it seems the concatentation operator requires a space before and after it:

$stmt = $this->conn->prepare("SELECT id, name, price, description, images, vendor_name, vendor_address, status FROM " . $this->foodItemsTable);

Sorry this my original Code:

PHP

class Food {    
   
    private $foodItemsTable = 'food_items'; 
    private $conn;
    
    public function __construct($db){
        $this->conn = $db;
    }       
    
    public function itemsList(){        
        $stmt = $this->conn->prepare("SELECT id, name, price, description, images, vendor_name, vendor_address, status FROM food_items ORDER BY rand()");               
        $stmt->execute();           
        $result = $stmt->get_result();      
        return $result; 
    }
}
