Json

Sanitizer that keeps only syntactically valid JSON strings.

This sanitizer does not decode, normalize, or re-encode JSON. It returns the original string when json_validate() accepts it, returns null for invalid JSON, and preserves null input as null. That makes it suitable for fields that store raw JSON while still rejecting malformed payloads.

• Full name: \PhalconKit\Filter\Sanitize\Json
