如何在firebase数据库中更新status = 0,其中status = 1。
我试过的是:
<?php
require __DIR__.'/vendor/autoload.php';
use Kreait\Firebase\Configuration;
use Kreait\Firebase\Firebase;
$firebase = new Firebase('LINK', $configuration);
$users = $firebase->get('/users');
for ($i=0; $i < count($users) ; $i++) {
$data = array('status' => '0');
$nodeUpdateContent = $firebase->update(['status' => '1'],$users[$i].'/presence/status');
print_r($nodeUpdateContent);
}
?>
但是当我在firebase数据库中看到它时,它没有更新任何东西。为什么这样?
我关注此链接:Firebase-php
使用以下链接更新数据:Update-data
我进入$users
:
<?php
[1] => Array
(
[presence] => Array
(
[loginTimestamp] => 1460117596561
[status] => 1
)
)
[2] => Array
(
[presence] => Array
(
[loginTimestamp] => 1460117596561
[status] => 1
)
)
[3] => Array
(
[presence] => Array
(
[loginTimestamp] => 1460117596561
[status] => 1
)
)
?>
我得到了回复:
$ nodeUpdateContent = $ firebase-&gt; update([&#39; status&#39; =&gt;&#39; 1&#39;],$用户[$ i]于&#39; /存在/状态&#39);
Array
(
[status] => 1
)
Array
(
[status] => 1
)
Array
(
[status] => 1
)
Array
(
[status] => 1
)
Array
(
[status] => 1
)
It is just printing the status which value is 1, but not updating it.
编辑:
getting error here: Array to string conversion --> $nodeUpdateContent = $firebase->update(['status' => '1'],$users[$i].'/presence/status');
答案 0 :(得分:0)
请查看我创建的以下git
根据上面的git,
$updated_json = array(
"loginTimestamp" => 1460117596561,
"status" => 2,
);
这是在第一个位置更新
$fboject->path = "/users/1";
$fboject->updateData($updated_json);
