用法
抽象示例
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');
更具体的示例
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
可以作为一个数组使用,因为它实现了 ArrayAccess
接口
// 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']);
/
也可以用作路径分隔符
$data->set('a/b/c', 'd'); echo $data->get('a/b/c'); // "d" $data->get('a/b/c') === $data->get('a.b.c'); // true
