推荐答案
看起来像javascript给我？这听起来像是你需要javascript的东西。 PHP无法单独执行此操作，因此如果您不想使用javascript，则需要使用AJAX。主持人应尽快将其移至javascript论坛。
Looks like javascript to me? And it sounds like something you would need javascript for anyway. PHP cannot do this alone, so if you don''t want to use javascript you will need AJAX. A moderator should move this to the javascript forum soon.

这与PHP有什么关系？
我会把它移到JavaScript论坛。
