			0 ignored issues – show Bug introduced 2016-04-16 12:59 UTC by Report Bug Copy Issue Report The expression `$spaces` of type `null\|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 Unused Code introduced 2016-04-08 13:26 UTC by Report Bug Copy Issue Report The assignment to `$sys` is unused. Consider omitting it like so `list($first,,$third)`. This checks looks for assignemnts to variables using the `list(...)` function, where not all assigned variables are subsequently used. Consider the following code example. <?php function returnThreeValues() { return array('a', 'b', 'c'); } list($a, $b, $c) = returnThreeValues(); print $a . " - " . $c; Only the variables `$a` and `$c` are used. There was no need to assign `$b`. Instead, the list call could have been. list($a,, $c) = returnThreeValues(); Loading history...
