What is a PHP trait?
Traits ¶ Traits are a mechanism for code reuse in single inheritance languages such as PHP. A Trait is intended to reduce some limitations of single inheritance by enabling a developer to reuse sets of methods freely in several independent classes living in different class hierarchies.
Why namespace is used in PHP?
In the PHP world, namespaces are designed to solve two problems that authors of libraries and applications encounter when creating re-usable code elements such as classes or functions: Name collisions between code you create, and internal PHP classes/functions/constants or third-party classes/functions/constants.
What is namespace example?
In computing, a namespace is a set of signs (names) that are used to identify and refer to objects of various kinds. Prominent examples for namespaces include file systems, which assign names to files. Some programming languages organize their variables and subroutines in namespaces.
Can namespace and class have same name?
The Framework Design Guidelines say in section 3.4 “do not use the same name for a namespace and a type in that namespace”. That is: namespace MyContainers. List { public class List { … } }
Which is this operator called?
Logical (or Relational) Operators:
Operator | Description | Example |

|| | Called Logical OR Operator. If any of the two operands is non zero then then condition becomes true. | (A || B) is true. |
What are the names of objects in space?
Galaxies. There are many other objects in our solar system as well as the planets and their moons.

Mercury.
What are some cars with space names?
Honda CR-V – 35.3 cubic feet.
Who invented the first spacecraft?
No one person invented the first spacecraft, but rather it was the work of a very large team. The first ship to safely put a man in space and orbit the earth was Vostok 1 , piloted by Yuri Gagarin in 1961. Sergei Korolëv was the lead designer of the Soviet space program at the time, but many other people were involved in the process.
