|
This is used to append 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 objects,
|
|
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.

<para>
|
|
The merge parameter respects array keys, so if you merge two
|
|
numerically indexed arrays, they may overwrite each other or result in
|
|
non-sequential keys. This is unlike the array_merge() function of PHP
|
|
which wipes out numerical keys and renumbers them.
