Dot Access Data
, (*1)
Given a deep data structure, access data by dot notation., (*2)
Requirements
For PHP (5.3+) please refer to version 1.0., (*3)
Usage
Abstract example:, (*4)
use Dflydev\DotAccessData\Data;
$data = new Data;
$data->set('a.b.c', 'C');
$data->set('a.b.d', 'D1');
$data->append('a.b.d', 'D2');
$data->set('a.b.e', ['E0', 'E1', 'E2']);
// C
$data->get('a.b.c');
// ['D1', 'D2']
$data->get('a.b.d');
// ['E0', 'E1', 'E2']
$data->get('a.b.e');
// true
$data->has('a.b.c');
// false
$data->has('a.b.d.j');
// 'some-default-value'
$data->get('some.path.that.does.not.exist', 'some-default-value');
// throws a MissingPathException because no default was given
$data->get('some.path.that.does.not.exist');
A more concrete example:, (*5)
use Dflydev\DotAccessData\Data;
$data = new Data([
'hosts' => [
'hewey' => [
'username' => 'hman',
'password' => 'HPASS',
'roles' => ['web'],
],
'dewey' => [
'username' => 'dman',
'password' => 'D---S',
'roles' => ['web', 'db'],
'nick' => 'dewey dman',
],
'lewey' => [
'username' => 'lman',
'password' => 'LP@$$',
'roles' => ['db'],
],
],
]);
// hman
$username = $data->get('hosts.hewey.username');
// HPASS
$password = $data->get('hosts.hewey.password');
// ['web']
$roles = $data->get('hosts.hewey.roles');
// dewey dman
$nick = $data->get('hosts.dewey.nick');
// Unknown
$nick = $data->get('hosts.lewey.nick', 'Unknown');
// DataInterface instance
$dewey = $data->getData('hosts.dewey');
// dman
$username = $dewey->get('username');
// D---S
$password = $dewey->get('password');
// ['web', 'db']
$roles = $dewey->get('roles');
// No more lewey
$data->remove('hosts.lewey');
// Add DB to hewey's roles
$data->append('hosts.hewey.roles', 'db');
$data->set('hosts.april', [
'username' => 'aman',
'password' => '@---S',
'roles' => ['web'],
]);
// Check if a key exists (true to this case)
$hasKey = $data->has('hosts.dewey.username');
Data may be used as an array, since it implements ArrayAccess interface:, (*6)
// Get
$data->get('name') === $data['name']; // true
$data['name'] = 'Dewey';
// is equivalent to
$data->set($name, 'Dewey');
isset($data['name']) === $data->has('name');
// Remove key
unset($data['name']);
/ can also be used as a path delimiter:, (*7)
$data->set('a/b/c', 'd');
echo $data->get('a/b/c'); // "d"
$data->get('a/b/c') === $data->get('a.b.c'); // true
