Headers already sent on CLI ?

[NorbertH]

Hi all ,

I get a "Headers already sent" when i call PW from the commandline. If i start output before including PW.
I know that is an Issue if doing output in a webbrowser before starting the actual session but i did not expect this in a CLI call.

Here is the script: 

<?php  namespace ProcessWire;

$path = "../../index.php";
$path = realpath($path);

echo ("\nPath: " .$path. "\n");
include $path;

Here is the Error:

I am not sure but shouldn't the session be started when running from CLI ?

Anyone solved this one? I want to bootstrap PW from an external console tool - a task runner.

I had a look and only thing I found is to add a $config->sessionAllow = false; in site/config.php. So this is not usable since it will disable sessions for the web site too.

Why not just including PW API at start of your main script?

EDIT:

@Ivan Gretsky Or you create a new include file (copy of index.php), like index-cli.php, to disallow sessions:

<?php namespace ProcessWire;

if (!defined("PROCESSWIRE")) define("PROCESSWIRE", 300); // index version
$rootPath = __DIR__;
if (DIRECTORY_SEPARATOR != '/') $rootPath = str_replace(DIRECTORY_SEPARATOR, '/', $rootPath);
$composerAutoloader = $rootPath . '/vendor/autoload.php'; // composer autoloader
if (file_exists($composerAutoloader)) require_once($composerAutoloader);
if (!class_exists("ProcessWire\\ProcessWire", false)) require_once("$rootPath/wire/core/ProcessWire.php");
$config = ProcessWire::buildConfig($rootPath);

$config->sessionAllow = false; // DISALLOWING SESSIONS <==============

// Rest of file...
