PHP页面无法在Bluemix上运行，但是在我的本地Web服务器上可以正常工作

Question

I'm trying to run this code

include 'safe/DAL.php';
$feedback = getAllCups();
if ($feedback != "Error.") {
    for ($x = 0; $x < count($feedback); $x++) {
    $tmp_cup = $feedback[$x];
    echo '<a href="#" class="list-group-item">';
    echo '<h4 class="list-group-item-heading">';
    echo $tmp_cup->getCupName() . ', ' . $tmp_cup->getYear();
    echo '</h4>';
    echo '<p class="list-group-item-text">Vinnare: Inte avslutad ännu</p>';
    echo'</a>';
    }
} else {
    echo '<a href="#" class="list-group-item">';
    echo'<h4 class="list-group-item-heading">Inga cuper hittades</h4>';
    echo'</a>';
}

on my bluemix app (which works fine on my local webserver, when I'm debugging)

It shows nothing, and stops any other code from being shown after this code.

I've tried to enable error reporting like this

error_reporting(E_ALL);

but this also, does not show anything.

Why does it work on my local webserver, but not on bluemix?

Answer 1

Likely, the answer to your problem lies in some error being generated by Bluemix or your code. In a production system, you don't want to output stack traces and other system errors to potential clients, so Bluemix generally forces errors to be logged only to log files.

From your command line, log in to Bluemix using the cf tool, then run this command to get the most recent logs from your app: cf logs <app_name> --recent .

The result should show you which file and line is causing the app crash (which may in fact be something within DAL.php).
