appendByRef() — append values by reference
void appendByRef(string varname,
mixed var,
bool merge);
This is used to
append() values
to the templates by reference.
With the introduction of PHP5, appendByRef() is not necessary for most
intents and purposes. appendByRef() is useful if you want a PHP array index value
to be affected by its reassignment from a template. Assigned object properties behave
this way by default.
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 PHP
array_merge() function
which wipes out numerical keys and renumbers them.
Example 14.5. appendByRef
<?php
// appending name/value pairs
$smarty->appendByRef('Name', $myname);
$smarty->appendByRef('Address', $address);
?>
