问题描述
我有一个大表单，我可以从 firebug 看到所有元素的值都被正确发送，但是当我打印_r($_POST) 时，只显示了 1000 个变量.我的 max_post_size 设置为 25M，所以我知道这不是问题，我在 php.ini 中搜索了诸如post"和max"之类的关键字，但没有找到任何内容.
I've got a large form and I can see from firebug that all of the elements' values are being sent properly, but when I print_r($_POST) there are only 1000 variables displayed. My max_post_size is set to 25M so I know that's not the issue and I searched through my php.ini for keywords like 'post' and 'max' and I didn't find anything.
1000 仅是我传递的元素的 1/4 左右，所以显然这对我来说是一个很大的问题，我非常感谢我能得到的任何帮助.
1000 is only about 1/4 of the elements that I'm passing so obviously this is a pretty big issue for me, I really appreciate any help I can get.
