This library implements Neo4J connectivity via its REST API.

Examples
--------

[](#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):

```
use com\neo4j\Graph;
use util\cmd\Console;

$g= new Graph('http://user:pass@neo4j-db.example.com: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()`:

```
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:

```
use com\neo4j\Graph;
use util\cmd\Console;

$g= new Graph('http://user:pass@neo4j-db.example.com: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
-----------------

[](#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`.
