Description
void
append_by_ref ( string varname, mixed var [, bool merge])
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.
Technical Note:
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.
Example 13-1. append_by_ref
<?php
// appending name/value pairs
$smarty->append_by_ref('Name', $myname);
$smarty->append_by_ref('Address', $address);
?>
