city[x] [y] 
x储存省的id
y储存x省的城市的id
如果city[x]下没有数据  
说明省是空的 可以删除
反之不能           怎么解?


回复讨论(解决方案)

count(city[x]) == 0

count(city[x]) == 0


这是能删除的语句么?    能不能写个全面点的。谢谢

foreach($city as $key->$item) {  if(count($itrm) <== 0) unset($city[$key]);}

foreach($city as $key->$item) {  if(count($itrm) <== 0) unset($city[$key]);}


谢谢哈  很好   但是我想说一下您那个代码是不是有地方写错了   ,哈哈
