Name

appendByRef() — 引用追加

说明

void appendByRef(string varname,
                 mixed var,
                 bool merge);

append() 一样,把值追加到数组,但以引用的方式来传递值。

技术说明

在PHP5中,appendByRef()在大部分时候都是没有必要的。只当你希望在模板中可以修改某个PHP数组的值,才有可能会使用到appendByRef(),当然更好的方法是通过传递对象、改变对象的成员变量来达到目的。

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 14.5. appendByRef()


<?php
// 追加键值对
$smarty->appendByRef('Name', $myname);
$smarty->appendByRef('Address', $address);
?>

   

参见 append(), assign()getTemplateVars().
