I have following json pattern

{"property":[{"id":"1","name":"Property 1"},{"id":"2","name":"Property 2"}]}

How can i validate json schema? Thanks in advance.

Do you want to verify the syntax or the content (property names and types)? — mcrumley

Use json_decode($string); to convert the JSON string into native PHP. If NULL is returned the string cannot be decoded. You can then use json_last_error() to get the error code, which may be helpful.

For strict JSON validation, you must use is_object($result) || is_array($result). Simple values like strings or numbers are allowed by json_decode() and many other parsers but are not strictly valid JSON. For looser validation checking for NULL is fine.
