帮我写一个太空人php

抱歉，我不是程序员，但我可以提供一些基本的PHP代码来创建一个太空人。

name = $name; $this->age = $age; $this->gender = $gender; $this->nationality = $nationality; $this->mission = $mission; } public function getName() { return $this->name; } public function getAge() { return $this->age; } public function getGender() { return $this->gender; } public function getNationality() { return $this->nationality; } public function getMission() { return $this->mission; } public function setName($name) { $this->name = $name; } public function setAge($age) { $this->age = $age; } public function setGender($gender) { $this->gender = $gender; } public function setNationality($nationality) { $this->nationality = $nationality; } public function setMission($mission) { $this->mission = $mission; } public function launch() { echo $this->name . " is ready for launch on mission " . $this->mission . "."; } public function spaceWalk() { echo $this->name . " is now performing a spacewalk."; } public function returnToEarth() { echo $this->name . " is returning to Earth from mission " . $this->mission . "."; } } // Create an Astronaut object $astronaut = new Astronaut("John Doe", 35, "Male", "American", "Apollo 11"); // Call methods $astronaut->launch(); $astronaut->spaceWalk(); $astronaut->returnToEarth(); ?>
