php中调用其他文件中的函数解决办法
php中调用其他文件中的函数
例如:我在common.php中写了一个函数
function get_provide_name($provide, &$pname)
{
if($provide == 0)
{
$pname = "中国移动";
}
else if($provide == 1)
{
$pname = "中国联通";
}
else if($provide == 2)
{
$pname = "中国电信";
}
else
{
$pname = "未知";
}
}
我在a.php中调用这个函数:
get_provide_name($provide, $pname);
如下使用:
总是显示方框。是为什么。
我现在只能把这些公共函数拷贝到 a.php中才会正常。
------解决方案--------------------
显示方框???查一下两个文件的编码
------解决方案--------------------
方框如一万米答案
其他建议
第一个 函数使用返回值不要使用&$
第二个 用switch 来控制吧 别这么 if if if 了...
$provide=intval($provide);
switch($provide):
case 0:
return "中国移动";
break;
case 1:
xxxx
break;
...
