mysqli_stmt_get_result incompatible with recommended config

[dleehr]

Not sure how to phrase this as an issue, but it complicates the installation issues #13 and conflicts with the recommended config in the wiki installation documentation.

The install doc recommends PHP 5.3. Recent changes to address SQL injection #17 have added calls to mysqli_stmt_get_result. This function exists in PHP 5.3 but only with the MySQL native driver (mysqlnd), which is not the default in 5.3.

mysqlnd became the default in PHP 5.4 (CentOS 7), so the official CentOS 5 and 6 packages aren't compatible with this change. There are third-party packages to get PHP 5.3 with mysqlnd, but I'm hesitant to start installing them.

Is there a recommendation on where to get a necessary version of php - I saw previous references to XAMPP but it's not mentioned in the installation documentation anymore.

In the most recent server migration, I've abandoned XAMPP in favor of conventional yum packages under CentOS. After considering the options, I chose to use the Remi yum repository and its packages for php (which include support for mysqlnd). Remi depends on EPEL, so this makes both available under CentOS 5.x:

rpm -Uvh http://ftp.osuosl.org/pub/fedora-epel/5/i386/epel-release-5-4.noarch.rpm
rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-5.rpm

Note that the Remi repository is disabled by default, since it can interfere with same-named packages in the base repos when using yum update, etc. So I enable it as needed for each package:

yum --enablerepo=remi install php-common php-mysqlnd

I think Mark Sutton mentioned php 5.3 was in use on the server, so we'll need to make sure this solution works for him too. (part of #56)

Thanks for the details about additional packages. I used EPEL and IUS to get PHP 5.4 with mysqlnd installed, with some guidance here:

IUS came out of rackspace and there is a mirror at Duke. Also, the package names are designed not to conflict with existing CentOS packages.

I updated the wiki about the PHP 5.4 requirement, with links to remi and ius.

Ah, good to know. The Remi packages (with name collisions) require a certain... vigilance. 😬

The latest code (as of 28d6fb4) should no longer require mysqlnd.
