通过php中的foreach访问多个变量

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

如果所有阵列具有相同的密钥，然后

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