How to convert array to string in php

Question

How can I do to dislay players list without array?

<?php
require __DIR__ . '/MinecraftQuery.class.php';

$Query = new MinecraftQuery( );

try
{
    $Query->Connect( 'localhost', 25565 );
    $players=print_r( $Query->GetPlayers( ));

}
catch( MinecraftQueryException $e )
{
    echo $e->getMessage( );
}

?>

`print_r` is only for debugging purposes. It prints to the screen, and has no return value. If you pass `true` as the second value, then it'll return a string and not print anything. I think you want something like `implode(',', $Query->GetPlayers())`. — gen_Eric, May 05 '14 at 18:51

You can use implode() to create a list separated by the character(s) of your choosing:

// comma spearated
echo implode(',', $players);  
// John,Brian,Matthew

// <br> after each one but the last
echo implode('<br>', $players);
// John<br>Brian<br>Matthew

it doesn't works Result Warning: implode() [function.implode]: Invalid arguments passed in C:\WebServ\httpd\mq\show.php on line 13 – user3605495 May 05 '14 at 18:57
Then `$players` is not an array – John Conde May 05 '14 at 18:58
I know ,it is a function, but it returns value what I want to implode – user3605495 May 05 '14 at 19:00
`$players` is **not** a function. It is a data type of some sort. Maybe an object. Maybe a string. Maybe something else. But it is not an array or function. – John Conde May 05 '14 at 19:01
public function GetPlayers( ) { return isset( $this->Players ) ? $this->Players : false; } – user3605495 May 05 '14 at 19:03
What can I do to get that result on the website: Player1, Player2? – user3605495 May 05 '14 at 19:04
I don't know. I don't know what data type `$players` is. Do `var_dump($players)` and post the output in your question. – John Conde May 05 '14 at 19:06
where I should put it? – user3605495 May 05 '14 at 19:07
After `$players=print_r( $Query->GetPlayers( ));` – John Conde May 05 '14 at 19:10
It returns bool(true) – user3605495 May 05 '14 at 19:13
That means you don't have a list of players. You have something that returns true or false. You need to review the code to find out how to get an array of layers names as that code won't do it. Once you do that my code will work for you. – John Conde May 05 '14 at 19:14
Wait, I forgot something – user3605495 May 05 '14 at 19:15
I don't enter the server Now it returns Array ( [0] => Player1 ) bool(true) – user3605495 May 05 '14 at 19:17
My code should work for the array although there is only one player listed so you won't actually see anything happen. – John Conde May 05 '14 at 19:18
May I send you all the code of MineQuery.class === Code === http://wklej.to/WfKnQ – user3605495 May 05 '14 at 19:20
