This library implements Neo4J connectivity via its REST API.

Examples

--------

Running a query can be done via `open()` (which yields one record at a time) or `query()` (which collects the results in an array):

```php

use com\neo4j\Graph;

use util\cmd\Console;

$g= new Graph('http://user:[email protected]:7474/db/data');

$q= $g->open('MATCH (t:Topic) RETURN t.name, t.canonical');

foreach ($q as $record) {

  Console::writeLine('#', $record['t.canonical'], ': ', $record['t.name']);

}

```

To retrieve single results (or *NULL* if nothing is found), use `fetch()`:

```php

if ($topic= $g->fetch('MATCH (t:Topic{id:%s}) RETURN t', $id)) {

  Console::writeLine('Found topic ', $topic);

}

```

Formatting parameters uses *printf*-like format tokens. These will take care of proper escaping and type casting:

```php

use com\neo4j\Graph;

use util\cmd\Console;

$g= new Graph('http://user:[email protected]:7474/db/data');

$g->query('CREATE (p:Person) SET t.name = %s, t.id = %d', $name, $id);

```

Batch statements can be executed via the `execute()` method.

Format characters

-----------------

* `%s`: Format a string

* `%d`: Format a decimal number

* `%f`: Format a floating point numer

* `%b`: Format a boolean

* `%v`: Copy value into parameter

* `%l`: Copy label into query

* `%c`: Copy literal into query

* `%%`: A literal percent sign

Positional parameters (starting at 1) may be used, e.g. `%2$s`.
