在 PHP 中,处理复杂数据结构的常用方法是使用数组和对象
- 创建一个包含多个数组的数组(二维数组):
$students = [ ['name' => 'Alice', 'age' => 20, 'major' => 'Computer Science'], ['name' => 'Bob', 'age' => 22, 'major' => 'Mathematics'], ['name' => 'Charlie', 'age' => 21, 'major' => 'Physics'] ];
- 遍历这个二维数组并显示每个学生的信息:
foreach ($students as $student) { echo "Name: " . $student['name'] . "
"; echo "Age: " . $student['age'] . "
"; echo "Major: " . $student['major'] . "
"; }
- 使用对象表示数据结构。首先,创建一个表示学生的类:
class Student {
public $name;
public $age;
public $major;
public function __construct($name, $age, $major) {
$this->name = $name;
$this->age = $age;
$this->major = $major;
}
public function display() {
echo "Name: " . $this->name . "
";
echo "Age: " . $this->age . "
";
echo "Major: " . $this->major . "
";
}
}
- 创建一个包含多个学生对象的数组:
$students = [ new Student('Alice', 20, 'Computer Science'), new Student('Bob', 22, 'Mathematics'), new Student('Charlie', 21, 'Physics') ];
- 遍历学生对象数组并调用每个对象的
display
方法:
foreach ($students as $student) { $student->display(); }
这些示例展示了如何使用 PHP 处理复杂数据结构并显示其内容。你可以根据需要调整代码以适应不同的数据结构和显示需求。
