PHP 表单按钮？
在 php 中制作表单，但“发送”按钮在浏览器中看起来像垃圾（它只是一个深灰色背景，顶部有“发送”），这以前从未发生过，而且它总是一个漂亮的圆形按钮“弹出”屏幕上，是一个明显的按钮！
Making a form in php, but the "Send" button looks like crap in the browser (its just a dark grey background with "send" on top) this has never happened before, and it was always a nice rounded button that "popped" of the screen, and was an obvious button!

您熟悉 Chrome 的开发人员工具或 Firefox 的 Firebug 吗？如果不是：两者都有方便的工具，可以让您“检查”元素并查看正在应用哪些 CSS 规则。我敢打赌，CSS 规则太宽泛，并且无意中适用于您的输入按钮。
您是否使用 CSS 重置文件？这些有时会很痛苦。不管怎样，CSS Normalize 可能会有所帮助

Are you familiar with Chrome's developer tools, or Firebug for Firefox? In case not: Both have handy tools that let you "inspect" elements and see what CSS rules are applying. I would place my bet that there is a CSS rule that is too broad, and inadvertently applies to your input button.
Are you using a CSS reset file? Those can occasionally be a pain. Either way, a CSS Normalize will probably be of help

让 PHP 在 HTML 中生成一个按钮，然后设置该按钮在单击时执行您想要的 PHP 功能。
Make PHP generate a button in HTML, then set the button to perform the PHP function you want when it's clicked.
