This is used to
|
|
<link linkend="api.append">append</link> values to the templates by reference.
|
|
If you append a variable by reference then change its
|
|
value, the appended value sees the change as well. For
|
|
<link linkend="advanced.features.objects">objects</link>,
|
|
append_by_ref() also avoids an in-memory copy of the appended object.
|
|
See the PHP manual on variable referencing for an in-depth
|
|
explanation. If you pass the optional third parameter of true,
|
|
the value will be merged with the current array instead of appended.
