实现这个结果你可以做

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

只适用于两个数组

Is it possible to have a foreach loop in PHP with multiple "index" variables, akin to the following (which doesn't use correct syntax)?

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

If not, is there a good way to achieve the same result?

to achieve just that result you could do

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

but that only works for two arrays
