DOMChildNode::before — Adds nodes before the node

Description

public DOMChildNode::before(DOMNode|string ...$nodes): void

Adds the passed nodes before the node.

Parameters

nodes: Nodes to be added before the node. Strings are automatically converted to text nodes.

Return Values

No value is returned.

Errors/Exceptions

DOM_HIERARCHY_REQUEST_ERR: Raised if the parent is of a type that does not allow children of the type of one of the passed nodes, or if the node to put in is one of this node's ancestors or this node itself.
DOM_WRONG_DOCUMENT_ERR: Raised if one of the passed nodes was created from a different document than the one that created this node.

Changelog

Version	Description
8.3.0	Calling this method on a node without a parent is now a no-op to align the behaviour with the DOM specification. Previously this threw a DOMException with code `DOM_HIERARCHY_REQUEST_ERR`.
