I just realised that a bit of PHP doesn’t execute correctly on one server,

I just realised that a bit of PHP doesn’t execute correctly on one server, but it does on another.

They’re both running Ubuntu 10.04 with PHP PHP 5.3.2 (PHP 5.3.2-1ubuntu4.2 with Suhosin-Patch (cli) (built: May 13 2010 20:03:45))

I’m testing using:

$f = function() {};

var_dump($f);
die();

On the server that works, the result is:

object(Closure)#1 (0) { }

On the one that doesn’t, the result is:

UNKNOWN:0

What am I missing?

[edit]

There seems to be an issue with having 2 closures in the same file:

<?php
$f = function() {};
$f2 = function() {};

var_dump($f);
var_dump($f2);
die();

Outputs:

UNKNOWN:0
object(Closure)#1 (0) {}

After some more Googling combined with ircmaxell’s tip at phpinfo, I got a hint at eaccelerator.

The server that ran the code correctly was running eaccelerator 0.9.6.1, the one that didn’t work was using 0.9.6.
