} elseif (Isallowed ($username, $page)) {
return TRUE;
} else {
return FALSE;

The web site of the server suddenly looks like this. Inexplicably suddenly this is the case. View the IUSR anonymous account, found it belongs to the Guests group, the site also allows anonymous access. No problem. Picture
The server happens to have a virus that is caused by the virus. Then try to change the partition, or not. It is important to try the following methods:
Create an account number that belongs to the Guests group. In IIS, replace the anonymous account in the Web site with a new
Oracle instance checks the quota. For activities that are assigned to a user scenario, only those activities that use space in the tablespace are counted in the limit. Activities that do not use space in the allocated tablespace, such as creating views or using temporal tablespace, do not affect quotas. Quotas are added when you use the purge clause to delete objects owned by a user, or when objects owned by users are automatically purged in the Recycle Bin.6. Apply the principle of least privi

Understanding OAuth 2.0 and oauth2.0
OAuth is an open network standard for authorization. It is widely used all over the world. The current version is version 2.0.
This article provides a concise and plain explanation of the OAuth 2.0 design concept and operation process. The main reference material is RFC 6749.
I. Application scenarios
To understand the applicability of OAuth, let me give a hypothetical example.
There is a "cloud printing" website that can print photos of users stored in Google

:
$ Array = ["key" => "value", "array" => [1, 2, 3, 4];$ Json = json_encode ($ array );Echo "{$ json} \ n ";
$ Object = json_decode ($ json );Print_r ($ object );
Output:
The code is as follows:
{"Key": "value", "array": [1, 2, 4]}StdClass Object([Key] => value[Array] => Array([0] => 1[1] => 2[2] => 3[3] => 4))
It is worth noting that json_decode () returns an object rather than an array by default. to return an array, set the second parameter to true.
