This is used to assign values to the templates by reference.
|
|
If you assign a variable by reference then change its
|
|
value, the assigned value sees the change as well. For
|
|
<link linkend="advanced.features.objects">objects</link>,
|
|
assign_by_ref() also avoids an in-memory copy of the assigned object.
|
|
See the PHP manual on variable referencing for an in-depth
|
|
explanation.
