append()
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')); ?>
