 *   - Parser finds all targeted relationships and outputs them with all intermediate results (looks like a tree).
 *     Resource attributes are already filtered.
 *   - Reply interpreter filters intermediate results and resource relationships and then send it to document.
 *   - The document is just a renderer which saves the input data in one of a few variations depending on settings.

		0 ignored issues – show Bug introduced 2016-11-15 00:32 UTC by Report Bug Copy Issue Report The expression `$traversableData` of type `null\|object\|array` is not guaranteed to be traversable. How about adding an additional type check? There are different options of fixing this problem. If you want to be on the safe side, you can add an additional type-check: $collection = json_decode($data, true); if ( ! is_array($collection)) { throw new \RuntimeException('$collection must be an array.'); } foreach ($collection as $item) { /** ... / } If you are sure that the expression is traversable, you might want to add a doc comment cast* to improve IDE auto-completion and static analysis: /** @var array $collection / $collection = json_decode($data, true); foreach ($collection as $item) { /* .. / } Mark the issue as a false-positive*: Just hover the remove button, in the top-right corner of this issue for more options.

		0 ignored issues – show Bug introduced 2016-02-24 00:46 UTC by Report Bug Copy Issue Report It seems like `$curFrame` defined by `$this->stack->end()` on line `152` can be `null`; however, `Neomerx\JsonApi\Encoder\Parser\Parser::getSchema()` does not accept `null`, maybe add an additional type check? Unless you are absolutely sure that the expression can never be null because of other conditions, we strongly recommend to add an additional type check to your code: /** @return stdClass\|null */ function mayReturnNull() { } function doesNotAcceptNull(stdClass $x) { } // With potential error. function withoutCheck() { $x = mayReturnNull(); doesNotAcceptNull($x); // Potential error here. } // Safe - Alternative 1 function withCheck1() { $x = mayReturnNull(); if ( ! $x instanceof stdClass) { throw new \LogicException('$x must be defined.'); } doesNotAcceptNull($x); } // Safe - Alternative 2 function withCheck2() { $x = mayReturnNull(); if ($x instanceof stdClass) { doesNotAcceptNull($x); } } Loading history...
