extends ASNObject
in package
implements
Countable, ArrayAccess, Iterator, Parsable
Class ASNObject is the base class for all concrete ASN.1 objects.
Interfaces, Classes, Traits and Enums
- Countable
- ArrayAccess
- Iterator
- Parsable
- The Parsable interface describes classes that can be parsed from their binary DER representation.

- fromBinary() : Construct|static
- Parse an instance of this class from its binary DER encoded representation.
- getBinary() : string
- Encode this object using DER encoding.
- getChildren() : array<string|int, ASNObject>
- getContent() : mixed
- Return the content of this object in a non encoded form.
- getFirstChild() : ASNObject
- getIdentifier() : string
- Returns all identifier octets. If an inheriting class models a tag with the long form identifier format, it MUST reimplement this method to return all octets of the identifier.
- getIterator() : mixed
- getNumberOfChildren() : mixed
- getObjectLength() : mixed
- Returns the length of the whole object (including the identifier and length octets).
- getType() : int
- Return the object type octet.

Return values
mixed —fromBinary()
Parse an instance of this class from its binary DER encoded representation.
public
static fromBinary(string &$binaryData[, int &$offsetIndex = 0 ]) : Construct|static
Parameters
- $binaryData : string
- $offsetIndex : int = 0
Tags
Return values
Construct|static —getBinary()
Encode this object using DER encoding.
public
getBinary() : string
Return values
string —the full binary representation of the complete object
getChildren()
public
getChildren() : array<string|int, ASNObject>
Return values
array<string|int, ASNObject> —getContent()
Return the content of this object in a non encoded form.
public
getContent() : mixed

Return values
string —Identifier as a set of octets
getIterator()
public
getIterator() : mixed
