如何为PHP配置引导程序
我只是试图从PHP和Bootstrap开始，但由于某种原因，我的网站无法识别引导程序。它不使用其设计，而是简单的HTML。这就是我的 index.php看起来像：
<!DOCTYPE html>
<html lang="en">
<head>
<link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-0evHe/X+R7YkIZDRvuzKMRqM+OrBnVFBL6DOitfPri4tjfHxaWutUpFmBp4vmVor" crossorigin="anonymous">
<title></title>
</head>
<body>
<script src="https://cdn.jsdelivr.net/npm/@popperjs/[email protected]/dist/umd/popper.min.js" integrity="sha384-Xe+8cL9oJa6tN/veChSP7q+mnSPaj5Bcu9mPX5F5xIGE0DVittaqT5lorf0EI7Vk" crossorigin="anonymous"></script>
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.min.js" integrity="sha384-kjU+l4N0Yf4ZOJErLsIcvOU2qSb74wXpOhqTvwVx3OElZRweTnQ6d31fXEoRD1Jy" crossorigin="anonymous"></script>
</body>
</html>
这就是我要用作组件的页面的外观：
<form role="form" method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>">
<div class="form-group row">
<label for="inputEmail" class="col-sm-2 col-form-label">Email</label>
<div class="col-sm-10">
<input type="email" class="form-control" id="inputEmail" name="email" placeholder="Email">
</div>
</div>
<div class="form-group row">
<label for="inputUser" class="col-sm-2 col-form-label">User Name</label>
<div class="col-sm-10">
<input type="text" class="form-control" id="inputUser" name="user" placeholder="Username">
</div>
</div>
<div class="form-group row">
<label for="inputPassword3" class="col-sm-2 col-form-label">Password</label>
<div class="col-sm-10">
<input type="password" class="form-control" id="inputPassword" name="password" placeholder="Password">
</div>
</div>
<div class="form-group row">
<div class="offset-sm-2 col-sm-10">
<input type="submit" value="Sign in" name="submit" class="btn btn-
primary"/>
</div>
</div>
</form>
有人可以看我的错误并告诉我它有什么问题吗？
I just tried to start with php and bootstrap but for some reason my website does not recognize bootstrap. It does not use it's design but rather simple html. This is how my
index.php looks like:
<!DOCTYPE html>
<html lang="en">
<head>
<link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-0evHe/X+R7YkIZDRvuzKMRqM+OrBnVFBL6DOitfPri4tjfHxaWutUpFmBp4vmVor" crossorigin="anonymous">
<title></title>
</head>
<body>
<script src="https://cdn.jsdelivr.net/npm/@popperjs/[email protected]/dist/umd/popper.min.js" integrity="sha384-Xe+8cL9oJa6tN/veChSP7q+mnSPaj5Bcu9mPX5F5xIGE0DVittaqT5lorf0EI7Vk" crossorigin="anonymous"></script>
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.min.js" integrity="sha384-kjU+l4N0Yf4ZOJErLsIcvOU2qSb74wXpOhqTvwVx3OElZRweTnQ6d31fXEoRD1Jy" crossorigin="anonymous"></script>
</body>
</html>
And this is how my page looks which I want to use as a component:
<form role="form" method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>">
<div class="form-group row">
<label for="inputEmail" class="col-sm-2 col-form-label">Email</label>
<div class="col-sm-10">
<input type="email" class="form-control" id="inputEmail" name="email" placeholder="Email">
</div>
</div>
<div class="form-group row">
<label for="inputUser" class="col-sm-2 col-form-label">User Name</label>
<div class="col-sm-10">
<input type="text" class="form-control" id="inputUser" name="user" placeholder="Username">
</div>
</div>
<div class="form-group row">
<label for="inputPassword3" class="col-sm-2 col-form-label">Password</label>
<div class="col-sm-10">
<input type="password" class="form-control" id="inputPassword" name="password" placeholder="Password">
</div>
</div>
<div class="form-group row">
<div class="offset-sm-2 col-sm-10">
<input type="submit" value="Sign in" name="submit" class="btn btn-
primary"/>
</div>
</div>
</form>
Could someone look at my error and tell me what is wrong with it?

From what you posted, nothing is wrong.
You may want to check your internet connection and perhaps browser. It works quite okay upon trying it here. If it persists, try downloading the bootstrap zip package, open it in your project directory and link it to your page manually.
