Json Schema Validation in PHP

I'm looking for a class that checks if a JSON object is valid based on a JSON Schema file, as described here:
http://davidwalsh.name/json-validation
I found only this, but it doesn't seem to be active
http://sourceforge.net/projects/jsonschemaphpv/
Any ideas?

You just want to make sure the format of the object is what you want it to be?

You could do a recursive comparison function like this:
Code: Select all
function validateObject($object, stdClass $pattern) {
if (!is_object($object) || !($object instanceof stdClass)) {
return false;
}
foreach ($pattern as $key => $property) {
if (!isset($object->$key)) {
return false;
} else {
if (is_object($property)) {
return validateObject($object->$key, $property);
}
}
return true;
}
}
Not tested. Just pass it the object, and an object to compare against.

It's more complicated than that.
See the first link I posted here.

Oh, I see. Hm, sorry, I don't know of any projects that do that. If you find one, please let us know though.
