在數組會話中存儲值-數組僅存儲最新值

Question

$user = hobaa;
$usernames = array();
$usernames['name'] = $user;


print_r($usernames['name']);

會發出類似

Array ( [name] => hobaa )

和print_r($usernames); 會把這個發出hobaa

如何使其保存多個值？

試着

$users = array("hobaa","test");
foreach($users as $user) {
    $usernames = array();
    $usernames['name'][] = $user;
   }
    print_r($usernames['name']);

但這只需要最后一個值。

請幫忙。 謝謝！

Answer 1

從此代碼：

foreach($users as $user) {
    $usernames = array();
    $usernames['name'][] = $user;
   }

從循環中刪除此行：

$usernames = array();

並將其放在循環上方，例如：

$usernames = array();
foreach($users as $user) {
    $usernames['name'][] = $user;
   }

然后再試一次。 在每次迭代中re-initializing數組時。

就像是：

$users = array("hobaa","test");
// a new usernames array to use
$usernames = array();
// 
foreach($users as $user) {
    array_push($usernames, $user);
}

print_r($usernames);

會給：

Array ( [0] => hobaa [1] => test ) 

Answer 3

在循環外定義$usernamse變量。 使用以下代碼：

$users = array("hobaa","test");
$usernames = array();
foreach($users as $user) {
    $usernames['name'][] = $user;
}
print_r($usernames['name']);
