Here is my solution with getters and setters:
<?php class Student { private $firstName; private $lastName; private $age; private $city; /** * @param mixed $firstName */ public function setFirstName($firstName): void { $this->firstName = $firstName; } /** * @param mixed $lastName */ public function setLastName($lastName): void { $this->lastName = $lastName; } /** * @param mixed $age */ public function setAge($age): void { $this->age = $age; } /** * @param mixed $city */ public function setCity($city): void { $this->city = $city; } /** * @return mixed */ public function getFirstName() { return $this->firstName; } /** * @return mixed */ public function getLastName() { return $this->lastName; } /** * @return mixed */ public function getAge() { return $this->age; } /** * @return mixed */ public function getCity() { return $this->city; } } $command = readline(); $students = []; while ($command !== "end") { $fields = explode(" ", $command); $newStudent = new Student(); $newStudent->setFirstName($fields[0]); $newStudent->setLastName($fields[1]); $newStudent->setAge($fields[2]); $newStudent->setCity($fields[3]); $students[] = $newStudent; $command = readline(); } $city = readline(); foreach ($students as $student) { if ($city == $student->getCity()) { echo $student->getFirstName() . " " . $student->getLastName() . " is " . $student->getAge() . " years old." . PHP_EOL; } }
