| * Introduce and use a proper ZPP check for ''int|float|string'' <php>$start</php> and <php>$end</php> parameters, this will cause <php>TypeError</php>s to be thrown when passing objects, resources, and arrays to <php>range()</php>. It will also cause a deprecation warning to be emitted when passing ''null''. | * Introduce and use a proper ZPP check for ''int|float|string'' <php>$start</php> and <php>$end</php> parameters, this will cause <php>TypeError</php>s to be thrown when passing objects, resources, and arrays to <php>range()</php>.
