Name
append() — append an element to an assigned array
Description
void append(mixed var);void append(string varname,
mixed var,
bool merge);
If you append
to a string value, it is converted to an array value and then
appended to. You can explicitly pass name/value pairs, or associative
arrays containing the name/value pairs. 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 PHP
array_merge() function
which wipes out numerical keys and renumbers them.
Example 13.1. append
<?php
// This is effectively the same as assign()
$smarty->append('foo', 'Fred');
// After this line, foo will now be seen as an array in the template
$smarty->append('foo', 'Albert');
$array = array(1 => 'one', 2 => 'two');
$smarty->append('X', $array);
$array2 = array(3 => 'three', 4 => 'four');
// The following line will add a second element to the X array
$smarty->append('X', $array2);
// passing an associative array
$smarty->append(array('city' => 'Lincoln', 'state' => 'Nebraska'));
?>
