+# JSON Structure PHP SDK
+
+A PHP SDK for JSON Structure schema and instance validation.
+
+## Requirements
+
+- PHP 8.1 or higher
+- BCMath extension (for large integer validation)
+- JSON extension
+
+## Installation
+
+### Via Composer
+
+```bash
+composer require json-structure/sdk
+```
+
+### Manual Installation
+
+Clone the repository and run:
+
+```bash
+cd php
+composer install
+```
+
+## Usage
+
+### Schema Validation
+
+Validate a JSON Structure schema document:
+
+```php
+ 'https://example.com/person.struct.json',
+ '$schema' => 'https://json-structure.org/meta/core/v0/#',
+ 'name' => 'Person',
+ 'type' => 'object',
+ 'properties' => [
+ 'name' => ['type' => 'string'],
+ 'age' => ['type' => 'int32'],
+ 'email' => ['type' => 'string']
+ ],
+ 'required' => ['name']
+];
+
+$validator = new SchemaValidator(extended: true);
+$errors = $validator->validate($schema);
+
+if (count($errors) === 0) {
+ echo "Schema is valid!\n";
+} else {
+ echo "Schema validation errors:\n";
+ foreach ($errors as $error) {
+ echo " - " . $error . "\n";
+ }
+}
+```
+
+### Instance Validation
+
+Validate a JSON instance against a JSON Structure schema:
+
+```php
+ 'https://example.com/person.struct.json',
+ '$schema' => 'https://json-structure.org/meta/core/v0/#',
+ 'name' => 'Person',
+ 'type' => 'object',
+ 'properties' => [
+ 'name' => ['type' => 'string'],
+ 'age' => ['type' => 'int32'],
+ 'email' => ['type' => 'string']
+ ],
+ 'required' => ['name']
+];
+
+$instance = [
+ 'name' => 'John Doe',
+ 'age' => 30,
+ 'email' => 'john@example.com'
+];
+
+$validator = new InstanceValidator($schema, extended: true);
+$errors = $validator->validate($instance);
+
+if (count($errors) === 0) {
+ echo "Instance is valid!\n";
+} else {
+ echo "Instance validation errors:\n";
+ foreach ($errors as $error) {
+ echo " - " . $error . "\n";
+ }
+}
+```
+
+### Extended Validation
+
+Enable extended validation features (conditional composition, validation keywords):
+
+```php
+ 'https://example.com/user.struct.json',
+ '$schema' => 'https://json-structure.org/meta/core/v0/#',
+ '$uses' => ['JSONStructureValidation'],
+ 'name' => 'User',
+ 'type' => 'object',
+ 'properties' => [
+ 'username' => [
+ 'type' => 'string',
+ 'minLength' => 3,
+ 'maxLength' => 20,
+ 'pattern' => '^[a-zA-Z][a-zA-Z0-9_]*$'
+ ],
+ 'age' => [
+ 'type' => 'int32',
+ 'minimum' => 0,
+ 'maximum' => 150
+ ]
+ ],
+ 'required' => ['username']
+];
+
+// Validate schema
+$schemaValidator = new SchemaValidator(extended: true);
+$schemaErrors = $schemaValidator->validate($schema);
+
+if (count($schemaErrors) > 0) {
+ echo "Schema errors: " . count($schemaErrors) . "\n";
+}
+
+// Validate instance
+$instance = [
+ 'username' => 'johndoe',
+ 'age' => 30
+];
+
+$instanceValidator = new InstanceValidator($schema, extended: true);
+$instanceErrors = $instanceValidator->validate($instance);
+
+if (count($instanceErrors) === 0) {
+ echo "Valid!\n";
+}
+```
