Answer 2

就是key:value
能否把email分开
ewr: [email protected];[email protected]
sdfsdf: [email protected];[email protected]

Answer 3

1.php：
<?php
require "SmartyConfig.php";
$a = array('ewr'=>array('[email protected]','[email protected]'),
           'sdfsdf' => array('[email protected]','[email protected]'));
$smarty->assign("arr",$a);
$smarty->display("1.htm");
?>1.htm：
<{foreach from=$arr key=K item=V}>
  <{assign var="tag" value=""}>
  <{$K}>:
  <{foreach from=$V key=k item=v}>
    <{$tag}><{$v}>
    <{assign var="tag" value=";"}>
  <{/foreach}>
  <br/><br/>
<{/foreach}>结果：
ewr: [email protected] ;[email protected] sdfsdf: [email protected] ;[email protected]

Answer 4

$a = array('ewr'=>array('[email protected]','[email protected]'),
           'sdfsdf' => array('[email protected]','[email protected]'));
$tag = ";";
foreach($a as $key => $val)
{
$email[] = $key.":".implode ($tag,$val);
}
echo $email[0]."\n";
echo $email[1];
exit;=======也可以用 array_keys()

Answer 5

多查查手册嘛，:),楼上两位已经点明了。
1. php
==========
foreach($a as $key=>$value)
{
echo $key.':'.implode(';',$value).'<br>';
}2. smarty
============
foreach($a as $key=>$value)
{
$arr[$key] = implode(';',$value).'<br>';
}
$smarty->assign("arr",$arr);tpl:
{foreach item=v from=$arr key=k}
{$k}:{$v}
{/foreach}

Answer 6

多谢了，结合smarty 和php 的 $email[$key] = implode ($tag,$value);Array
(
    [ewr] => [email protected];[email protected];[email protected]
    [213] => [email protected];[email protected]
    [sdfsdf] => [email protected];[email protected]
)OK了
smarty 中不可以用impolde吧，，smarty知识太匮乏了，，
