<br />
Scalar Type Hints:<br />
<br />
1.Type declarations simply means specifying which type of variable is being set instead of allowing PHP to set this automatically.<br />
2.Type declarations can help you define what should occur so that you get the expected results. <br />
3.With PHP 7, by adding scalar type hints and enabling strict requirements, it is hoped that more correct and self-documenting PHP programs can be written. It also gives you more control over your code and can make the code easier to read.<br />
4.By default, scalar type-declarations are non-strict, which means they will attempt to change the original type to match the type specified by the type-declaration.<br />
<br />
Return Type Deceleration:<br />
<br />
1.PHP 7 also supports Return Type Declarations.<br />
2.To specify the return type, we add a colon and then the type right before the opening curly bracket. <br />
3.function add(int $a, int $b): int{<br />
4.The same strictness rules apply as with the type hints: if “strict mode” is disabled, return values that can be converted to the preferred type are allowed. If you enable “strict mode” this code will throw a type error.<br />
<br />
<br />
Anonymous classes<br />
<br />
With anonymous classes you can define a class and instantiate an object inline.<i class="fa fa-language transViewIcon clickable" title="Translation"></i>
