导读：for ( $i =0; $i count ( $array ); $i ++) { for ( $j =0; $j count ( $array [ $i ]); $j ++) { echo $array [ $j ][userid]; } } 因为它是个多维数组,一般用 foreach ( $arr as $key = $value ){ echo Key:$key;Value:$value n ; } Array([0]=Array([user

for($i=0;$i<count($array);$i++)
{
for($j=0;$j<count($array[$i]);$j++)
{
echo $array[$j][userid];
}
}

因为它是个多维数组,一般用

foreach ($arr as $key => $value) {
echo "Key: $key; Value: $valuen";
}
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] => ) )
