Expressions

php-cypher-dsl can be used to build complex queries in Cypher.

Examples

To match only movies released in the 1990s:

$released = variable("nineties")->property("released");
$expression = $released->gte(1990)->and($released->lt(2000));

$this->assertSame("((nineties.released >= 1990) AND (nineties.released < 2000))", $expression->toQuery());

To match all actors except Tom Hanks:

$name = variable("actor")->property("name");
$expression = $name->notEquals("Tom Hanks");

$this->assertSame("(actor.name <> 'Tom Hanks')", $expression->toQuery());

Raw expressions

It is possible to use raw text in an expression.

$released = variable("nineties")->property("released");
$expression = $released->gte(1990)->and(Query::rawExpression("(nineties IS NOT NULL)"));

$this->assertSame("((nineties.released >= 1990) AND (nineties IS NOT NULL))", $expression->toQuery());
