TYPO3 Core

I lost much time figuring out why I get a blank page when I try to access the extension manager or install extensions in Install script.

Although I enabled any possible setting to display errors no errors were thrown so I ended up debugging TYPO3. I set $TYPO3_CONF_VARS['EXT']['extList'] = '' to see if there is a corrupt extension I've installed. But it has not changed anything. I was wondering if there is a corrupt core extension although this typo3 source is used by other websites too.

When I debugged TYPO3 I noticed that it stops the logic after including a specific extension's ext_emconf.php. As it was included with @include the error messages were hidden, but this does not prevent the PHP process to stop. So I got only a blank page.

/**
 * Returns the $EM_CONF array from an extensions ext_emconf.php file
 *
 * @param    string        Absolute path to EMCONF file.
 * @param    string        Extension key.
 * @return    array        EMconf array values.
     */
    public static function includeEMCONF($path, $_EXTKEY) {
        $EM_CONF = NULL;

@include($path);
        if (is_array($EM_CONF[$_EXTKEY])) {
            return self::fixEMCONF($EM_CONF[$_EXTKEY]);
        }
        return FALSE;
    }

The prefix should be removed here. If the file is corrupt, it should be visible. If you want to handle a missing file, PHP offers other ways to fulfill that. is evil.

Here is a small example for @include: https://gist.github.com/939886
