Debug in some cases is not working - possible fix - line 29 in DebugHelper

[tinodj]

Hi, please change this:

php-amqplib/PhpAmqpLib/Helper/DebugHelper.php

Line 29 in 31c6ec8

define('STDOUT', fopen('php://stdout', 'w'));

to:
define('STDOUT', fopen('php://output', 'w'));

It makes things easier when using php-fpm. Output is logged directly on screen, while php://stdout is discarded by default configurations.

This is how php-fpm is configured by default:

; Redirect worker stdout and stderr into main error log. If not set, stdout and
; stderr will be redirected to /dev/null according to FastCGI specs.
; Note: on highloaded environement, this can cause some delay in the page
; process time (several ms).
; Default Value: no
;catch_workers_output = yes

so it sends everything to /dev/null.

However, for debugging purposes it is much better option writing to a file instead on output.
