Library with common utility classes for Neo4j
Installation

composer require graphaware/neo4j-common
Graph
Label
Object representation of a Node Label.
use GraphAware\Common\Graph\Label; $label = new Label("User"); echo $label->getName(); // Returns (string) "User" // or static construction $label = Label::label("User");
Node
Object Representation of a Node. The node object extends PropertyBag
.
use GraphAware\Common\Graph\Node; $node = new Node(1, array("User", "Person")); $node->getId(); // Returns (int) 1 $node->getLabels(); // Returns an array of \GraphAware\Common\Graph\Label objects
Relationship
Object Representation of a Relationship. The relationship object extends PropertyBag
.
use GraphAware\Common\Graph\Relationship; $rel = new Relationship(1, RelationshipType::withName("RELATES"), $node, $node2); echo $rel->getType(); // Returns (string) "RELATES" var_dump($rel->isType(RelationshipType::withName("RELATES"))); // Returns (bool) true
Direction (Enum) : representation of a Relationship Direction
use GraphAware\Common\Graph\Direction; $direction = new Direction(Direction::INCOMING); echo $direction; // Returns (string) "INCOMING" // Or static call construction $direction = Direction::OUTGOING; echo $direction; // Returns (string) "OUTGOING"
Valid values are INCOMING
, OUTGOING
and BOTH
.
RelationshipType
Object representation of a relationship type.
use GraphAware\Common\Graph\RelationshipType; $relType = RelationshipType::withName("FOLLOWS"); echo $relType->getName(); // Returns (string) "FOLLOWS" echo (string) $relType; // implements __toString method : Returns (string) "FOLLOWS"
Cypher
Statement and StatementCollection
Utility classes representing Cypher's statements. Both Statement

Contains also StatementInterface
and StatementCollectionInterface
used in most GraphAware's PHP libraries.
Statement
Represents a Cypher statement with a query and an array of parameters. Also the Statement accepts a tag
argument default to null;
use GraphAware\Common\Cypher\Statement; $statement = Statement::create("MATCH (n) WHERE id(n) = {id} RETURN n", array("id" => 324)); echo $statement->getQuery(); // Returns (string) "MATCH (n) WHERE id(n) = {id} RETURN n" echo count($statement->getParameters()); // Returns (int) 1
StatementCollection
Represents a collection of Statement
objects. Is also Taggable.
use GraphAware\Common\Cypher\Statement GraphAware\Common\Cypher\StatementCollection; $collection = new StatementCollection(); $collection->add(Statement::create("MATCH (n) RETURN count(n)")); print_r($collection->getStatements()); echo $collection->isEmpty();
