I have an application I am writing in PHP5, using the CodeIgniter framework. I have it running on both Windows (using Xampp) and Ubuntu (using standard Apache, PHP, MySQL stack).
I have a form, that takes XML, parses it (using simpleXML) and posts the results into a database.
On Windows - no problem, works as intended.
On Linux - big problem. It errors out.
I have double checked the XML, and it's fine.
I removed a large amount of the XML, and it seems that it is OK.
I think it's related to the size of the XML string being posted from the form, but am not sure. Again, on Windows it's OK - on Linux, it errors out.
The size of the data posted in the form is ~160k (yeah, that's a lot of text, but it's automated - AND it's gonna eventually be about 200k).
The error is below.
Any help much appreciated.
Fatal error: Uncaught exception 'Exception' with message 'String could not be parsed as XML' in /var/www/ci/system/application/controllers/system.php:49 Stack trace: #0 /var/www/ci/system/application/controllers/system.php(49): SimpleXMLElement->__construct('') #1 [internal function]: System->add_system() #2 /var/www/ci/system/codeigniter/CodeIgniter.php(233): call_user_func_array(Array, Array) #3 /var/www/ci/index.php(115): require_once('/var/www/ci/sys...') #4 {main} thrown in /var/www/ci/system/application/controllers/system.php on line 49
Line 49 looks like this:
$xml = new SimpleXMLElement($this->input->post('form_systemXML'));
EDIT - FIXED
Found the issue. Suhosin is installed on Ubuntu. in the file /etc/php5/apache2/conf.d/suhosin.ini, I enabled the line suhosin.post.max_value_length = 65000 and changed the value to 195000. Restarted Apache, and all good. Thanks for the pointers guys.
It seems like you're running the Suhosin PHP extension. Please have a look at the configuration documentation at: http://www.hardened-php.net/suhosin/configuration.html.
The relevant option seems to be (I've never used the Suhosin extension): suhosin.post.max_value_length and/or suhosin.request.max_value_length
