function get_lm($need_zhlm){ $top_nav_name=array(array(url=>u( radelist,set), ame=>淘宝联盟设置),array(url=>u(mall,set), ame=>综合联盟),array(url=>u(paipai_order,set), ame=>拍拍易推广设置)); $zhlm=$webset[zhlm]; $need_zhlm=0; if($zhlm[open]==1){ $need_zhlm=1; $top_nav_name=array_merge($top_nav_name,array(array(url=>u(mall,duomai_set), ame=>多麦联盟),array(url=>u(mall,weiyi_set), ame=>唯一联盟),array(url=>u(mall,wujiumiao_set), ame=>59秒联盟),array(url=>u(mall,yiqifa_set), ame=>亿起发联盟),array(url=>u(mall,linktech_set), ame=>领科特联盟),array(url=>u(mall,chanet_set), ame=>成果联盟),array(url=>u(mall,yqh_set), ame=>一起惠),array(url=>u(ijia,set), ame=>全网搜索))); } return $top_nav_name;}

zhlm为数据库字段，我希望$need_zhlm在数据库zhlm字段为0时赋值为0，zhlm字段为1时赋值为1，请帮我看看这样写是否正确

$webset 是哪里来的？最好依照SOLID 原则啦，貌似你的代码隔离性不好啊

理论上你那样写是没问题的

但既然是作为一个参数,我更愿意这样写

function get_lm($need_zhlm = 0) { $top_nav_name = array(array(url => u( radelist, set), ame => 淘宝联盟设置), array(url => u(mall, set), ame => 综合联盟), array(url => u(paipai_order, set), ame => 拍拍易推广设置)); $zhlm = $webset[zhlm]; if ($zhlm[open] == 1) { $need_zhlm = 1; $top_nav_name = array_merge($top_nav_name, array(array(url => u(mall, duomai_set), ame => 多麦联盟), array(url => u(mall, weiyi_set), ame => 唯一联盟), array(url => u(mall, wujiumiao_set), ame => 59秒联盟), array(url => u(mall, yiqifa_set), ame => 亿起发联盟), array(url => u(mall, linktech_set), ame => 领科特联盟), array(url => u(mall, chanet_set), ame => 成果联盟), array(url => u(mall, yqh_set), ame => 一起惠), array(url => u(ijia, set), ame => 全网搜索))); } return $top_nav_name; }

直接在参数里写好默认值

还有,正如jp928所说,$webset这个变量从哪里来的,难道是个在函数外部的全局变量?

function get_lm($need_zhlm=0){ $top_nav_name=array(array(url=>u( radelist,set), ame=>淘宝联盟设置),array(url=>u(mall,set), ame=>综合联盟),array(url=>u(paipai_order,set), ame=>拍拍易推广设置)); $zhlm=$webset[zhlm]; $need_zhlm=0; if($zhlm[open]==1){ $need_zhlm=$need_zhlm; //我希望$need_zhlm在数据库zhlm字段为0时赋值为0，zhlm字段为1时赋值为1,你这样不就行了???直接赋值 $top_nav_name=array_merge($top_nav_name,array(array(url=>u(mall,duomai_set), ame=>多麦联盟),array(url=>u(mall,weiyi_set), ame=>唯一联盟),array(url=>u(mall,wujiumiao_set), ame=>59秒联盟),array(url=>u(mall,yiqifa_set), ame=>亿起发联盟),array(url=>u(mall,linktech_set), ame=>领科特联盟),array(url=>u(mall,chanet_set), ame=>成果联盟),array(url=>u(mall,yqh_set), ame=>一起惠),array(url=>u(ijia,set), ame=>全网搜索))); } return $top_nav_name;}
