The mysqli_num_rows() function is an inbuilt function in PHP 
which is used to return the number of rows present in the result set. 
It is generally used to check if data is present in the database or not. 
To use this function, it is mandatory to first set up the connection with the MySQL database.
	// Setting up connection with database Geeks 
	$con = mysqli_connect("localhost", "root", "", "testing"); 
	// Check connection 
	if (mysqli_connect_errno()) { 
		echo "Database connection failed."; 
	// Fetch Query
	$query = "SELECT Username, Password FROM users"; 
	// Execute the query and store the result set 
	$result = mysqli_query($con, $query); 
	if ($result) { 
		// it return number of rows in the table. 
		$row = mysqli_num_rows($result); 
		if ($row) { 
			 	printf("Number of row in the table : " . $row); 
		// close the result. 

// Output : Number of row in the table : 5
