It's my understanding that as long as the reference is a variable or a
function, the only difference is the removal of the '&' symbol when calling a
function that receives the reference:
logic that remains the same:
function foo( &$some_var ) { // receives reference
$some_var = 'some value';
}
allowed old calling syntax:
$my_var = 'original value';
foo( &$my_var ); // obvious it's being passed as a reference
New syntax:
$my_var = 'original value';
foo( $my_var ); // still a reference, just no special syntax when calling
I've been running Drupal 6 in php 5.4, and only had to make a few adjustments
like the above to run the latest D6 version. (I get a number of other warnings
from other php changes, but this one seems fixed by the above.)
