正文概述
  1. for($i=0;$i<count($array);$i++) 
  2. { 
  3. for($j=0;$j<count($array[$i]);$j++) 
  4.   { 
  5.      echo $array[$j][userid]; 
  6.   } 
  7. } 

因为它是个多维数组,一般用

  1. foreach ($arr as $key => $value) { 
  2.     echo "Key: $key; Value: $value
    n"
    ; 
  3. } 
  4. Array ( [0] => Array ( [userid] => 1 [username] => 刘振鹏 [status] => 0 [userpwd] => ) [1] => Array ( [userid] => 2 [username] => 刘鹏飞 [status] => 0 [userpwd] => ) [2] => Array ( [userid] => 3 [username] => 刘朋 [status] => 0 [userpwd] => ) [3] => Array ( [userid] => 4 [username] => admin [status] => 0 [userpwd] => ) [4] => Array ( [userid] => 11 [username] => admin [status] => 0 [userpwd] => ) [5] => Array ( [userid] => 12 [username] => admin [status] => 0 [userpwd] => ) [6] => Array ( [userid] => 13 [username] => liuzp [status] => 0 [userpwd] => ) [7] => Array ( [userid] => 14 [username] => lzp [status] => 0 [userpwd] => ) )
