StrObj

StrObj reads, writes and validates nested PHP arrays, objects and JSON documents through slash-separated paths such as order/items/0/sku. It has no runtime dependencies beyond the JSON extension, so it fits any framework or plain PHP application.

use StrObj\StringObjects;

$order = StringObjects::instance($json);

$order->get('order/items/0/sku');         // "A-1"
$order->get('order/note', 'n/a');         // "n/a" — the field is missing
$order->set('order/shipping/city', 'Ankara');
$order->isValid();                        // checks the configured rules

Behaviors

StringObjects::instance() has two behaviors, selected with the behavior option:

• Consistent (the default) — stored values are returned exactly as stored, defaults apply only to missing or rejected values, values are detached from the input, and configuration is checked strictly.
• Legacy (['behavior' => Behavior::LEGACY]) — keeps the 2.x results that existing applications rely on.

See Migration from 2.1 for the differences.
