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] => ) )
下面是对二维数组的用法
for($i=0;$i
for($j=0;$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";
}
