PHP error while creating array

I apologize in advance because I am very new to programming and I am in a rush to get this completely as I am working on a deadline this is also my first time using this webpage or virtually any forum.

I need to create a simple array and loop in PHP that stores and prints the name of 3 tennis players.

My code looks like this:

html>
  <head>
    <title>Tennis Players Array</title>
  </head>
  <body>
  <form action="" method="POST">
	<input type="text" name="name">
	<input type="submit" value = "submit">
</form>
    <p>
		<?php
			$request = $_SERVER['REQUEST_METHOD'];
			$name = $_POST['name'];
				if ($request == 'GET')
				{
					// Do Nothing
				}
				else if ($request == 'POST')
				{
					$TennisPlayers = array("Roger Federer", "Rafael Nadal", "Novak Djokovic");
					echo $TennisPlayers;
				}
		?>
	</p>
  </body>
</html>
Run code


I am getting an error when running the code:

"Note: Convert array to string in C: \ xampp \ htdocs \ Problem3 \ ProblemThree.php on line 19"

Line 19

echo $TennisPlayers;
Run code


And that probably won't be the only bug if fixed.

Look, I understand you are not going to give me a straight answer to this question, and I appreciate it, although I would really like to help him with that. PS Sorry for such a question, rookie. Thank!:)

Because you can't echo

a array

to print the array you need to use print_r

or var_dump

. But in your case, you need to show the values ​​so that you can use them like



echo implode(',',$TennisPlayers);
+2

You cannot print an array, you need to code the array to get each element:

foreach ( $TennisPlayers as $single_player ) {

    echo $single_player . '<br>';

}


This code will print:

Roger Federer
Rafael Nadal
Novak Djokovic

You must use print_r or var_dump if you want to show the array. You cannot use echo.

 // doesn't work
echo $TennisPlayers;

// works
var_dump($TennisPlayers);

// works
echo '<pre>';
print_r($TennisPlayers);
echo '</pre>';
