怎么把两个函数分开,然后可以得到$str的返回值。


回复讨论(解决方案)

        public function huancheng($key)        {             global $str;             $key="永兴村到山水人家";             $str="";             $keys=explode('到',$key);             $json = @file_get_contents("http://api.map.baidu.com/direction/v1?mode=transit&origin=".$keys[0]."&destination=".$keys[1]."&region=舟山&output=json&ak=gfPnxaaiPyNIhM7c3eZ1kmEL");             $ar = json_decode($json,true);             array_walk_recursive($ar, 'funv');             return $str;            }         function funv($v, $k)          {           global $str;           if($k == 'stepInstruction')            {$str.= strip_tags($v);}          }

为什么要抱着 php 5.2 不放呢?

别岐视php5.2.
第一次见有人这样写东西
public function huancheng($key)
{

function funv($v, $k)
{

}
return $str;
}

代码看不懂。不好意思。

        public function huancheng($key)        {             global $str;             $key="永兴村到山水人家";             $str="";             $keys=explode('到',$key);             $json = @file_get_contents("http://api.map.baidu.com/direction/v1?mode=transit&origin=".$keys[0]."&destination=".$keys[1]."&region=舟山&output=json&ak=gfPnxaaiPyNIhM7c3eZ1kmEL");             $ar = json_decode($json,true);             array_walk_recursive($ar, 'funv');             return $str;            }         function funv($v, $k)          {           global $str;           if($k == 'stepInstruction')            {$str.= strip_tags($v);}          }

为什么要抱着 php 5.2 不放呢?

主要bae上不支持啊,另外你这样写也报错的Warning: array_walk_recursive() [function.array-walk-recursive]: Unable to call funv()

如果 funv 是作为类的方法出现的,则应
array_walk_recursive($ar, array($this, 'funv'));

如果 funv 是作为类的方法出现的,则应
array_walk_recursive($ar, array($this, 'funv'));

老大,你太给力了!!!!
