Matrix version: 2.2.2.1
EE Version: v2.2.2
PHP Version 5.4.13
When I save an image to a File field, it properly saves and publishes the content. But when I return to the entry to Edit it, the matrix file data is gone.
Our server was recently force-migrated which bumped up the PHP version a bit.
Anything else I should check?
In case this helps anyone else out there I fixed it with the same versions of EE (2.2.2) and Matrix (2.2.2.1) as the OP and with php 5.4.x and php5.5.x.
Essentially I did a diff between the latest version of Matrix (2.5.10) and a couple of older ones and tracked it down to these two parts.

Replace this:
if ($this->_data_exists($data))
{
if (is_array($data))
{
$filedir = $data['filedir'];
$filename = $data['filename'];
}
else if (preg_match('/^{filedir_([0-9]+)}(.*)/', $data, $matches))
{
$filedir = $matches[1];
$filename = $matches[2];
}
}
With this:
if ($data)
{
if (is_array($data) && ! empty($data['filedir']) && ! empty($data['filename']))
{
$filedir = $data['filedir'];
$filename = $data['filename'];
}
else if (is_string($data) && preg_match('/^{filedir_([0-9]+)}(.*)/', $data, $matches))
{
$filedir = $matches[1];
$filename = $matches[2];
}
}

Line: 1820
After this: $field_id = $this->settings['field_id'];
Add this:
if (empty($data))
{
$data = array();
}
Often problems like this are caused by the PHP Suhosin security patch, which has a configuration option to limit the number of POST variables in a single request. If you have a long publish page or lots of matrix fields it is easy to exceed this limit if it's set too low.
The way to check this is to look at your PHP Info (under Tools > Utilities > PHP Info in the CP) and search for Suhosin or configuration options like suhosin.post.max_vars. Ideally this would be set very high (say 2000+).
I was having the same issue with the following versions:
EE 2.7.2 Matrix 2.5.9 PHP 5.4.17
Upgrading to Matrix 2.5.10 fixed my issue.
