Question

I have inherited a client site which crashes every 3 or 4 days. It is built using the zend-framework with which I have no knowledge.

The following code:

<?php     // Make sure classes are in the include path.    ini_set('include_path', ini_get('include_path') . PATH_SEPARATOR . 'lib' . PATH_SEPARATOR . 'app' . DIRECTORY_SEPARATOR . 'classes');      // Use autoload so include or require statements are not needed.     require_once 'Zend/Loader.php';     Zend_Loader::registerAutoload();      // Run the application.     App_Main::run('production'); 

Is causing the following error:

 [Tue Sep 02 12:58:45 2008] [error] [client 78.***.***.32] PHP Warning: require_once(Zend/Loader.php) [function.require-once]: failed to open stream: No such file or directory in /srv/www/vhosts/example.co.uk/httpdocs/bootstrap.php on line 6  [Tue Sep 02 12:58:45 2008] [error] [client 78.***.***.32] PHP Fatal error: require_once() [function.require]: Failed opening required 'Zend/Loader.php' (include_path='.:.:/usr/share/php5:/usr/share/php5/PEAR') in /srv/www/vhosts/example.co.uk/httpdocs/bootstrap.php on line 6  

I don’t even know where to begin trying to fix this. My level of knowledge of PHP is intermediate but like I said, I have no experience with Zend. Also, contacting the original developer is not an option.

The interesting thing is that even though the code is run every time a page of the site is hit the error is only happening every now and then.

I believe it must be something to do with the include_path but I am not sure.

Answer 1

for a start I think your include path should maybe have a trailing slash. Here is an example of mine :

    set_include_path('../library/ZendFramework-1.5.2/library/:../application/classes/:../application/classes/excpetions/:../application/forms/');  

You bootstrap file will be included by another file (probably an index.php file). This means that if your include path is relative (as mine is) instead of absolute, then the path at which Loader.php is looked for changes if the file including bootstrap.php changes.

For example, I have two index.php files in my Zend app, one for the front end, and one for the admin area. These index files each need there own bootstrap.php with different relative paths in because they are included by different index files, which means they have to be relative to the original requested index file, not the bootstrap file they are defined within.

This could explain why your problem is intermittent, there could be another file including the bootstrap somewhere that is only used occasionally. I’d search through all the sites files for ‘bootstrap.php’ and see all the places which are including / requiring this file.
