how to use a second function inside a class?

[BrainPill]

This question is based on the table and class set up in my former posting.

The difference is that I want to have a second function inside the class. 

The name of this second function is: check_amount () . 

I do not see any output or action at all in this function. 

I hope someone can help to make the example work.

Script 1:

 

		<?php 

		$amount = '' ; // 5, 20 , 15, 9 
		$fruit_type = 'grapes'; // grapes , apple, strawberry, banana
		$dbname = "test_fruit";


		include 'fruit-class4a.php';
		$object = new fruit_stock( '$fruit_type','$dbname'); 
		 
		$object -> get_fruit($amount, $fruit_type, $dbname);
		 


		// $object ->get_fruit($amount, $fruit_type, $dbname)->check_amount($amount);
		 

		var_dump($object);

		echo $object -> get_fruit($amount, $fruit_type, $dbname);


		?>

 

Script 2:

 

	<?php 
			
			class fruit_stock {
			 
				var $amount;
				var $dbname;
				
			public function get_fruit($amount, $fruit_type, $dbname) {
				  
			 global $amount; 
			var_dump($fruit_type);
			var_dump($dbname);
		  
		
			include 'login-test.php'; // login credentials
	 
			$conn = new mysqli($servername, $username, $password, $dbname);
	 
			if ($conn->connect_error) {
			die("Connection failed: " . $conn->connect_error);
			}

			// PREPARED 

		if ($stmt = $conn->prepare("SELECT amount FROM fruit WHERE fruit_type = ? ; " )) { 
	 

	 
		$stmt->bind_param('s', $fruit_type); //  
	 
		$stmt->execute();
	   
		$stmt->bind_result($amount);
	 
		 
		 
		 
		while ($stmt->fetch()) {
			
		   var_dump($amount);
		  
			   return $amount;	 
			 
		} 
	}
	 
	} 
			 
		
			public function check_amount($amount) {
			 
			  $amount = $amount + 1;
			 var_dump($amount);
			 return $amount; } } ?>

class whatever {



function func1 {

do stuff
}

function func2 {

do stuff
}



}

object = new whatever(blah,blah2);

object->funct1();
object->funct2();
