Passing by refrence in FOREACH

[moishy]

I have a problem when passing by refrence using FOREACH():

[PHP]
foreach ($array as &$value)
{if ($value <= 0)
{$value+=12;}}
[/PHP]

It should have worked, but I got a error:

Parse error: syntax error, unexpected '&', expecting T_VARIABLE or '$'

It even worked on a local testing server!

[PHP]
foreach ($array as &$value)
{if ($value <= 0)
{$value+=12;}}
[/PHP]

foreach reference work on/for PHP5, as long as i know.

So what is a loophole for earlier versions?
