App Context API for PHP SDK

This page describes App Context (formerly Objects v2). To upgrade from Objects v1, refer to the migration guide.

App Context provides easy-to-use, serverless storage for user and channel data you need to build innovative, reliable, scalable applications. Use App Context to easily store metadata about your application users and channels, and their membership associations, without the need to stand up your own databases.

PubNub also triggers events when object data is changed: set, updated, or removed from the database. At the same time, making a request to set the same data that already exist, doesn't trigger any event. Clients can receive these events in real time and update their front-end application accordingly.

User

Get Metadata for All Users

Returns a paginated list of UUID Metadata objects, optionally including the custom data object for each.

Method(s)

To Get All UUID Metadata you can use the following method(s) in the PHP SDK:

getAllUUIDMetadata()
    ->includeFields(Array[String => Boolean])
    ->filter(String)
    ->sort(String | Array[String])
    ->limit(Integer)
    ->page(Array[String => String])
    ->sync()

* required

Parameter	Description
`includeFields()` Type: Array[String => Boolean] Default: n/a	Include respective additional fields in the response. Key value array where keys are one of `totalCount` or `customFields` and value is a boolean. Set `customFields` to fetch `custom` fields or not. Set `totalCount` to request `totalCount` to be included in paginated response. By default, `totalCount` is omitted.
`filter()` Type: String Default: n/a	Expression used to filter the results. Only objects whose properties satisfy the given expression are returned. The filter language is defined here.
`sort()` Type: String or Array[String] Default: n/a	String or Array of String property names to sort by, and an optional sort direction. Available options are `id`, `name`, and `updated`. Use `asc` or `desc` to specify sort direction, or omit to take the default sort direction (ascending). For example: `name:asc`
`limit()` Type: integer Default: `100`	Number of objects to return in response. Default is `100`, which is also the maximum value.
`page()` Type: Array[String => String] Default: n/a	Use for pagination. Key value array where keys are one of `next` or `prev` and value is a random string returned from the server, indicating a specific position in a data set. Set `prev` to a previously-returned string for fetching the previous page. Set `next` to a previously-returned string for fetching the next page.
