php数组转换字符串及复选框如何勾选中，应用到函数 implode  explode

复选框被选中后如何保存数据，表单提交过来为数组，要转换字符串 用到函数implode

if(!empty($_POST[\'yuyan\'])){
$bbyuyan=implode(",", $_POST[\'yuyan\']);
}

if(!empty($_POST[\'fenge\'])){
$bbfenge=implode(",", $_POST[\'fenge\']);
}

if(!empty($_POST[\'biaoqian\'])){
$bbbiaoqian=implode(",", $_POST[\'biaoqian\']);
}

复选框显示如何被勾选，这时候要把字符串转换数组 用到函数 explode

if(!empty($users[\'yuyan\'])){
$users[\'yuyan\']=explode(",",$users[\'yuyan\']);
}

if(!empty($users[\'fenge\'])){
$users[\'fenge\']=explode(",",$users[\'fenge\']);
}

if(!empty($users[\'biaoqian\'])){
$users[\'biaoqian\']=explode(",",$users[\'biaoqian\']);
}

复选框如何被显示，下面实例

<input name="biaoqian[]" value="晚上可录" type="checkbox" {#foreach item=biaoqian1 from=$users.biaoqian#}{#if $biaoqian1 eq "晚上可录"#} checked="checked" {#/if#}{#/foreach#}/>晚上可录
<input name="biaoqian[]" value="周六可录" type="checkbox" {#foreach item=biaoqian1 from=$users.biaoqian#}{#if $biaoqian1 eq "周六可录"#} checked="checked" {#/if#}{#/foreach#}/>周六可录
<input name="biaoqian[]" value="周日可录" type="checkbox" {#foreach item=biaoqian1 from=$users.biaoqian#}{#if $biaoqian1 eq "周日可录"#} checked="checked" {#/if#}{#/foreach#}/>周日可录
<input name="biaoqian[]" value="起录价低" type="checkbox" {#foreach item=biaoqian1 from=$users.biaoqian#}{#if $biaoqian1 eq "起录价低"#} checked="checked" {#/if#}{#/foreach#}/>起录价低

复选框要比单选框要复杂些，单选框跟普通表单一样，这里不说了
