PHP Array Usage _php tutorial

Array ([0] = = Array ([userid] = 1 [Username] = Liu Zhenpeng [status] = 0 [Userpwd] =) [1] = = Array ([user ID] + 2 [Username] = + Liu [status] = 0 [Userpwd] = [2] = = Array ([userid] + 3 [username] + Liu Bong [Status] = 0 [Userpwd] = [3] = = Array ([userid] = 4 [Username] = admin [status] + 0 [userpwd] = >) [4] = = Array ([userid] = [Username] + admin [status] = 0 [userpwd] = =) [5] = = Array ([US Erid] = [Username] + admin [status] + 0 [userpwd] = [6] = = Array ([userid] [username] =& Gt LIUZP [status] = 0 [Userpwd] = [7] = = Array ([userid] = [Username] = LZP [status] = 0 [USERPW D] =))

for ($j =0; $j<>

}

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