升级到ubuntu 14.04后使用aigaion2开发PHP

Question

I have been using the web based bibliography management system aigaion2 for some years, accumulating thousands of references & linked pdf files. However after upgrading from ubuntu 12.04 to 14.04 - with a change in the version of PHP - this fails to give me a log-in screen. There are 2 warning messages;

I am at a loss how to deal with this - does anybody have this working with a recent PHP version or might have any idea how to fix this. From the aigaion website, it seems the package does not have any active maintainers any longer.

A PHP Error was encountered

Severity: Warning

Message: Creating default object from empty value

Filename: gettext/gettext.inc

Line Number: 195

A PHP Error was encountered

Severity: Warning

Message: Cannot modify header information - headers already sent by (output started at /data1/aigaion2/codeigniter/libraries/Exceptions.php:166)

Filename: helpers/url_helper.php

Line Number: 541

I'm trying to use Aigaion too. I got some errors. You will find new release here : On source.forge : Source.Forge This release replaces old php "commands" to some new ones eregi to preg_replace split to explode, etc.

It seems that a 2.5 beta exists : Release 2.5 beta I'll check today.

For your problem, I did a small update in the module aigaion2\\aigaionengine\\libraries\\gettext\\gettext.inc ligne 193

function _bind_textdomain_codeset($domain, $codeset) {
  global $text_domains;
  /*
   * MVT 150505 : Add !isset due to warning errors
   * It is a temporary features. It should be better
   * to migrate to a new PHP Release
   * Tested with Xamp / Php 5.6.8
   * I did this patch in order to use Aigaion with no errors
   * I don't have a large knowledge in PHP. Sorry
   */
  if (!isset($text_domains[$domain]))
        $text_domains[$domain] = new stdClass();
  $text_domains[$domain]->codeset = $codeset;

}

I found an answer here : Empty objects

This should be a little patch...
