Question

Running Zend Framework on PHP 5.1.6 - patch or fix for ksort()?

Answer 1

+2 A:

I suppose you could change the inheritance of Zend_View_Helper_Placeholder_Container or Zend_View_Helper_Placeholder_Container_Abstract to supply your own implementation of ArrayObject::ksort. Something like:

class CompatibilityArrayObject extends ArrayObject {
    public function ksort () {
        // here be dragons
    }
}


abstract class Zend_View_Helper_Placeholder_Container_Abstract
extends CompatibilityArrayObject {
    ...
}

You don't know how many more problems there are though. If the requirement says PHP 5.2.4, that's what you should run it on.

@deceze - thanks, this is the sort of thing I was wondering about. But I am sure many people find themelves in this boat; RHEL 5 is going to be the standard in many enterprise environments for a good time to come. I was hoping someone could direct me to a complete solution; I don't want to reinvent the wheel extending ZF, since after all the entire point of ZF is to avoid reinventing the wheel

Answer 2

+2 A:

Hi,

I had the same issue today. I found solution in this blog post.

Add the following snippet in /Zend/View/Helper/Placeholder/Container/Abstract.php:

/**
* Sort the array by key
*
* @return array
*/
public function ksort()
{
    $items = $this->getArrayCopy();
    return ksort($items);
}

+1 But the core issue remains: You don't know how many more incompatibilities there are.

@deceze - the core issue is that the ZF team in their ivory tower decided to break compatibility with earlier PHP versions, in the full knowledge that there were a great many production environments like the one discussed here where they CANNOT CHANGE THE PHP VERSION installed or they lose the support warranties from Red Hat and their hosting provider. They won't upgrade the PHP, so the alternatives are patch ZF to work or rewrite the app without ZF. Which would you rather do in my place?

@Flubba The problem with patching is that it's hard to know when it's done. You will need to do a lot of testing to make sure you patched every missing requirement. I'm not saying it's not the solution, I'm just pointing out the drawbacks. You're stuck in a pretty bad place, so you need to weigh all pros and cons. How hard would it be to port the application to an older version of ZF? That may be a task with a better definable scope.

@deceze - thanks... I'm not disagreeing with your appraisal of the drawbacks. I'll consider downgrading the ZF to an earlier version but at the moment patching is less work and timescales are tight. This resource looked useful: http://zfcompat.wolf-u.li/ but it doesn't actually show the minimum required version for Zend_View_Helper, so needs to be taken with a pinch of salt. Thanks for your answer; I've upvoted it but accepted the other one because it linked to actual code. Thanks for your help!
