PHP Server Error 500 when Echo doesnt exist? - php

Question

My php code works fine when I add in an echo in a certain spot, but when I remove the simple echo "hello"; line it doesnt load the php page and it just shows Server Error 500.
The following code works:
require 'steam.php';
$steam = new steam();
$api = "FC1D74A835829EB99A571235A499638A";
$query = 'ari9';
$communityID = $steam->getID($query, $api);
$userInfo = $steam->getUserInfo($communityID, $api);
echo "hello";
$info = array(
'communityID' => $communityID,
'steamID' => $steam->$convertToSteamID($communityID),
'personaname' => $userInfo['personaname'],
'profileurl' => $userInfo['profileurl'],
'lastlogoff' => $userInfo['lastlogoff'],
);
foreach ($info as $key => $value) {
if (strlen($value)===0) {
$info[$key] = false;
}
echo $key." -> ".$value."<br>";
}
echo json_encode($info);
And the following code does not work:
require 'steam.php';
$steam = new steam();
$api = "FC1D74A835829EB99A571235A499638A";
$query = 'ari9';
$communityID = $steam->getID($query, $api);
$userInfo = $steam->getUserInfo($communityID, $api);
$info = array(
'communityID' => $communityID,
'steamID' => $steam->$convertToSteamID($communityID),
'personaname' => $userInfo['personaname'],
'profileurl' => $userInfo['profileurl'],
'lastlogoff' => $userInfo['lastlogoff'],
);
foreach ($info as $key => $value) {
if (strlen($value)===0) {
$info[$key] = false;
}
echo $key." -> ".$value."<br>";
}
echo json_encode($info);
and the following code does not work:
require 'steam.php';
$steam = new steam();
$api = "FC1D74A835829EB99A571235A499638A";
$query = 'ari9';
$communityID = $steam->getID($query, $api);
$userInfo = $steam->getUserInfo($communityID, $api);
$info = array(
'communityID' => $communityID,
'steamID' => $steam->$convertToSteamID($communityID),
'personaname' => $userInfo['personaname'],
'profileurl' => $userInfo['profileurl'],
'lastlogoff' => $userInfo['lastlogoff'],
);
foreach ($info as $key => $value) {
if (strlen($value)===0) {
$info[$key] = false;
}
echo $key." -> ".$value."<br>";
}
echo json_encode($info);
echo "Hello";
The first piece of code has the echo on line 9 and the second one is identical to the first except the echo on line 9 is removed. I'm puzzled by this.

The issue is that this $steam->$convertToSteamID is looking for a function with the name of whatever that variables value is. The reason you get the 500 when there isn't an echo is because when you send the echo that serves a 200. There should be events in your log displaying the error. You can't have 2 status codes though on a page.
So just change your function call to:
$steam->convertToSteamID
and you should be fine.
