		0 ignored issues – show Bug introduced 2016-06-12 15:57 UTC by Report Bug Copy Issue Report The property `_formatter` does not exist. Did you maybe forget to declare it? In PHP it is possible to write to properties without declaring them. For example, the following is perfectly valid PHP code: class MyClass { } $x = new MyClass(); $x->foo = true; Generally, it is a good practice to explictly declare properties to avoid accidental typos and provide IDE auto-completion: class MyClass { public $foo; } $x = new MyClass(); $x->foo = true; Loading history...

		0 ignored issues – show Documentation introduced 2016-06-12 15:57 UTC by Report Bug Copy Issue Report `$tokens` is of type `object<Kadet\Highlighter\Parser\Tokens>`, but the function expects a `object<Kadet\Highlighter...enIterator>\|string\|null`. It seems like the type of the argument is not accepted by the function/method which you are calling. In some cases, in particular if PHP’s automatic type-juggling kicks in this might be fine. In other cases, however this might be a bug. We suggest to add an explicit type cast like in the following example: function acceptsInteger($int) { } $x = '123'; // string "123" // Instead of acceptsInteger($x); // we recommend to use acceptsInteger((integer) $x); Loading history...
