Data.PHPSession.Types

Types used for representing PHP data types from encoding and decoding a PHP session.

PHP session types

type PHPSessionVariableList = [(ByteString, PHPSessionValue)]

Holds the "top-level" session variables and their value contents.

data PHPSessionClassName

Represents the name of a PHP class.

data PHPSessionValue

PHPSessionValue Represents a PHP value, which may be a number, string, array, object, boolean, null, or references.

• PHPSessionValueArray represents an array as a list of key-value pairs of values of type PHPSessionValue.
• PHPSessionValueObject is similar to PHPSessionValueArray but also includes a class name of type PHPSessionClassName.
• PHPSessionValueObjectSerializeable represent objects of which their classes implement Serializeable to handle their own serialization and don't use the normal serialization format for its contained objects.
• PHPSessionValueBool, PHPSessionValueInt, PHPSessionValueFloat, PHPSessionValueNull, and PHPSessionValueString represent basic types boolean, integer, floats, null and string respectively.
• PHPSessionValueFloat stores the number representation as an Either Int Double to preserve instances where the number representation is actually an integer. It should be noted that the re-encoded value is usually rounded unlike PHP's representation.
• PHPSessionValueMisc stores a few other types such as references and values which follow the general serialization format but aren't recognized by the decoder. A list of PHPSessionAttr provides the information for reconstructing the serialized representation when re-encoding this type of value.

data PHPSessionAttr

PHPSessionAttr are values associated with PHPSessionValueMisc to inspect and generally re-encode the necessary information for that value.

PHPSessionAttrInt Int

PHPSessionAttrFloat Double

PHPSessionAttrNested [PHPSessionValue]

data PHPSessionDecodingError

PHPSessionDecodingError are error types that can be returned if decoding did not succeed. They are returned by the Either versions of the decoding functions.

• PHPSessionStringEmpty is given if the decoder got an empty byte sequence.
• PHPSessionCouldntDecodeSerializablePast is given if the decoding does not succeed while in the particular byte sequence for a class that implements Serializable.
• PHPSessionCouldntDecodeObjectPast is given if the decoding does not succeed while in the particular byte sequence for a PHP object value.
• PHPSessionCouldntDecodeStringPast is given if the decoding does not succeed while in the particular byte sequence for a PHP string.
• PHPSessionCouldntDecodePast is given if the decoding does not succeed while decoding common byte sequences which are composed mainly of PHPSessionAttr forms.
• PHPSessionValueNotFullyDecoded is given if the byte sequence is not fully decoded to a PHPSessionValue when using decodePHPSessionValue or decodePHPSessionValueEither.
• PHPSessionNotFullyDecoded is given.if the byte sequence is not fully decoded to a PHPSessionVariableList when using decodePHPSession or decodePHPSessionEither.
