void append mixed var void append string varname mixed var void append string varname mixed var boolean merge This is used to append an element to an assigned array. 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. 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. // passing name/value pairs $smarty->append("Name","Fred"); $smarty->append("Address",$address); // passing an associative array $smarty->append(array("city" => "Lincoln","state" => "Nebraska"));
