   PHP数组 怎么从指定位置开始查询?

  $arr = array("a"=>1, "b"=>2, "c"=>3, "d"=>4, "e"=>5);

  比如我想从c开始循环,怎么写?

  ------解决方案--------------------

  這個好點。

  $arr = array("a"=>1, "b"=>2, "c"=>3, "d"=>4, "e"=>5);

  $index = array_search('c',array_keys($arr));

  $arr1 = array_slice($arr, $index);

  foreach($arr1 as $key=>$val){

  echo $key.'='.$val.'

  ';

  }
