App Context API for PubNub 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 set or removed from the database. Clients can receive these events in real time and update their front-end application accordingly.

Set `prev` to a previously-returned string for fetching the previous page. Set `next` to a previously-returned string for fetching the next page.

API limits

To learn about the maximum length of parameters used to set channel members metadata, refer to REST API docs.

Basic Usage

$response = $pubnub->setMembers()
    ->channel("channel")
    ->uuids([
        "uuid",
        [ id => "uuid1" ],
        [ id => "uuid2", custom => [ hello => "world" ]]
    ])
    ->custom([
        "a" => "aa",
        "b" => "bb",
    ])
    ->includeFields([ "totalCount" => true, "customFields" => true, "customUUIDFields" => true, "UUIDFields" => true ])
    ->sync();

Response

The setMembers() operation returns a PNMembersResult which contains the following fields:

`getData()`	Array[PNMembersResultItem]	List of member metadata results
`getTotalCount()`	Integer	Number of items returned in the data
`getPrev()`	String	Random string returned from the server, indicating a specific position in a data set. Used for backward pagination, it fetches the previous page, enabling access to earlier data.
`getNext()`	String	Random string returned from the server, indicating a specific position in a data set. Used for forward pagination, it fetches the next page, allowing you to continue from where you left off.

Data is an array of PNMembersResultItem which contains the following fields:

Parameter	Type	Description
`getUUID()`	PNMember	UUID metadata
`getCustom()`	String	stdClass object containing your custom fields
`getUpdated()`	String	The last updated date and time
`getETag()`	String	The entity tag

Channel is a PNMember which contains the following fields:

Parameter	Type	Description
`getId()`	String	Unique user identifier
`getName()`	String	Display name for the user
`getExternalId()`	String	User's identifier in an external system
`getProfileUrl()`	String	The URL of the user's profile picture
`getEmail()`	String	The user's email address
`getCustom()`	stdClass	Object containing your custom fields
`getUpdated()`	String	The last updated date and time
`getETag()`	String	The entity tag

Remove Channel Members

Remove members from a Channel.

Method(s)

To Remove Channel Members you can use the following method(s) in the PHP SDK:

removeMembers()
    ->channel(String)
    ->uuids(Array[String])
    ->includeFields(Array[String => Boolean])
    ->filter(String)
    ->sort(String | Array[String])
    ->limit(Integer)
    ->page(Array[String => String])
    ->sync();

Parameter	Type	Required	Default	Description
`channel()`	String	Yes		Unique channel identifier
`uuids()`	Array[String]	Yes		Array of members to remove from the channel
`custom()`	Array or StdClass	Yes		Object of key-value pairs with supported data types.
`includeFields()`	Array[String => Boolean]	Optional		Include respective additional fields in the response. Key value array where keys are one of `totalCount`, `customFields`, `customUUIDFields` or `UUIDFields` and value is a boolean. Set `customFields` to fetch `custom` fields or not. Set `customUUIDFields` to fetch `custom` UUID fields or not. Set `UUIDFields` to fetch UUID fields or not. Set `totalCount` to request `totalCount` to be included in paginated response. By default, `totalCount` is omitted.
`filter()`	String	Optional		Expression used to filter the results. Only objects whose properties satisfy the given expression are returned. The filter language is defined here.
`sort()`	String or Array[String]	Optional		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()`	integer	Optional	`100`	Number of objects to return in response. Default is `100`, which is also the maximum value.
`page()`	Array[String => String]	Optional		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.

Basic Usage

App Context Filtering Language Definition

The filtering language for App Context is similar to the stream filtering language.

Note the following:

Date/time properties, such as updated, must be compared to valid date/time strings formatted according to ISO 8601.
The LIKE operator supports wildcards denoted by the * character. A wildcard matches any sequence of arbitrary Unicode characters, including the empty sequence. The literal asterisk is matched when escaped using the backslash (\) character.
Values used with LIKE must be properly encoded just like any other string value. Thus, in order to escape an asterisk, the raw value must contain \\*.
The entire expression must be properly URL-encoded when used in the query string.

Custom property filtering

You can't filter by custom properties.

<expression>           ::= <and_expression> ( "||" <and_expression> )*
<and_expression>       ::= <binary_condition> ( "&&" <binary_condition> )*
<binary_condition>     ::= "!" <binary_condition> | "(" <expression> ")" | <relational_condition>
<relational_condition> ::= <property_path> <relational_operator> <value>
<property_path>        ::= <property_name> ( "." <property_name> )*
<property_name>        ::= <identifier> | "[" <string> "]"
<value>                ::= <string> | <number> | "true" | "false" | "null"

Tokens

<identifier>           ::=  <letter> | "$" | "_" ( <letter> | "$" | "_" | <digit> )*
<relational_operator>  ::= "==" | "!=" | "<=" | ">=" | "<" | ">" | "LIKE"
<string>               ::= <double_quote> ( "\" <double_quote> | "\" <special_char>
                            | "\" "u" <hex_digit> <hex_digit> <hex_digit> <hex_digit>
                            | <unicode_char> - <double_quote> - "\" )* <double_quote>
show all 26 lines

Sample object filtering operations

The following date/time comparison returns results that were modified on or after August 31st, 2019 (UTC):

updated >= "2019-08-31T00:00:00Z"

The following wildcard expression returns results whose name starts with the letter X:

name LIKE 'X*'

The following escaped wildcard expression returns results whose name contains an asterisk:

name LIKE '*\\**'
