多个变量通过php中的foreach访问

Question

foreach ($courses as $course, $sections as $section, $example as $example)

任何添加超过2的方法？

我只知道2个变量的解决方案。

foreach (array_combine($courses, $sections) as $course => $section)

Answer 1

如果所有数组都有相同的键，那么

foreach ($courses as $key => $course)
{
    echo $sections[$key], $example[$key];
}
