我之前确实发布了一些东西，这次我将发布所有内容。我收到了错误消息，当我尝试在本地主机上拉它时，它不会显示出来。代码如下：

这是includeindex.php

if ($_POST['submit'] != "") {
    if ($_POST['name'] != "") {
        session_start();
        $_SESSION['name'] = $_POST['name'];
        TopNavigation("PHP Includes Example - ECA236", "PHP Includes", $_SESSION['name']);
    } else {
        header("Location:includindex.php");
        exit;
    }
} else {
    TopNavigation("PHP Includes Example - ECA236", "PHP Includes");
    echo "<div class=\"formtable\">\n";
    echo "<br>";
    echo "<form action=\"" . $PHP_SELF . "\" method=\"post\">\n";
    echo "Please enter your name:<input type=\"text\" name=\"name\">\n";
    echo "<input type=\"submit\" class=\"btnSubmit\" value=\"Enter\" name=\"submit\">\n";
    echo "</form>\n";
    echo "<br>";
    echo "</div>\n";
    Footer();
}

?>

if（$\u POST['submit']！=“”）{
如果（$_POST['name']！=“”）{
会话_start（）；
$_SESSION['name']=$_POST['name']；
TopNavigation（“PHP包括示例-ECA236”、“PHP包括”、$\u会话['name']）；
}否则{
标题（“位置：includindex.php”）；
if ($_POST['submit'] != "") {
    if ($_POST['name'] != "") {
        session_start();
        $_SESSION['name'] = $_POST['name'];
        TopNavigation("PHP Includes Example - ECA236", "PHP Includes", $_SESSION['name']);
    } else {
        header("Location:includindex.php");
        exit;
    }
} else {
    TopNavigation("PHP Includes Example - ECA236", "PHP Includes");
    echo "<div class=\"formtable\">\n";
    echo "<br>";
    echo "<form action=\"" . $PHP_SELF . "\" method=\"post\">\n";
    echo "Please enter your name:<input type=\"text\" name=\"name\">\n";
    echo "<input type=\"submit\" class=\"btnSubmit\" value=\"Enter\" name=\"submit\">\n";
    echo "</form>\n";
    echo "<br>";
    echo "</div>\n";
    Footer();
}

?>

出口
}
}否则{
TopNavigation（“PHP包括示例-ECA236”，“PHP包括”）；
回音“\n”；
回声“
”；
回音“\n”；
echo“请输入您的姓名：\n”；
回音“\n”；
回音“\n”；
回声“
”；
回音“\n”；
页脚（）；
}
?>

这个是头

<?php
function TopNavigation($pagetitle, $pageheading, $username = '') {
    echo "<html>\n";
    echo "  <head>\n";
    echo "  <title>" . $pagetitle . "</title>\n";
    echo "  <link href=\"../style.css\" type=\"text/css\" rel=\"stylesheet\">";
    echo "  </head>\n";
    echo "  <body>";
    echo "      <h1>" . $pageheading . "</h1>\n";
    echo "      <hr>\n";
    echo "      <p class=\"tiny\">" . date("F j,Y") . "</p>";
    if ($username != '') {
        echo "<div align=\"center\">\n";
        echo "<a href=\"includeindex.php\">Use a different name</a> | <a href=\"about.php\">About</a> | <a href=\"signout.php\">Signout</a>\n";
        echo "</div>\n";
        echo "<p>Welcome. " . $username . "!";
    }
}

function Footer() {
    echo "</body>\n";
    echo "</html>\n";
}

?>

这是关于.php的

<?php
session_start();
include("include/header.php");
if (!isset($_SESSION['name'])) {;
    header("Location:includeindex.php");
    exit;
} else {
    TopNavigation("About Me -ECA236", "About Me", $_SESSION['name']);

    echo "<p>Here is a little about me. I am a mother of twin girls who are 9 </p>\"n;
    echo " < p>I been married for 5 years but been with my husband for 11 years </p > \"n;
    echo "<p > I am attending college for Computer Programming and Database Mangament </p > \"n;
    echo "<p > After I get done with this degree I am want to go back for Web Design </p > \"n;
    echo "<p > since half my classes are web design now . I enjoy camping,bon fires and  </p > \"n;
    echo "<p > playing video games, hanging out with friends and family .</p > \"n;
    Footer();
}
?>

这是signout.php

<?php
session_start();
if (isset($_SESSION['name'])) {
    session_destroy();
    session_start();
}
header("Location:includeindex.php");
exit;
?>

我根本无法让它出现和工作。我不知道它为什么不这样做。谁能帮帮我吗

无论我修复了什么，我总是会出错，当你在线查看时，它不会显示出来

下面是我得到的错误：注意：第19行C:\wamp\www\includeindex.PHP中的未定义变量：PHP\u SELF

if ($_POST['submit'] != "") {
    if ($_POST['name'] != "") {
        session_start();
        $_SESSION['name'] = $_POST['name'];
        TopNavigation("PHP Includes Example - ECA236", "PHP Includes", $_SESSION['name']);
    } else {
        header("Location:includindex.php");
        exit;
    }
} else {
    TopNavigation("PHP Includes Example - ECA236", "PHP Includes");
    echo "<div class=\"formtable\">\n";
    echo "<br>";
    echo "<form action=\"" . $PHP_SELF . "\" method=\"post\">\n";
    echo "Please enter your name:<input type=\"text\" name=\"name\">\n";
    echo "<input type=\"submit\" class=\"btnSubmit\" value=\"Enter\" name=\"submit\">\n";
    echo "</form>\n";
    echo "<br>";
    echo "</div>\n";
    Footer();
}

?>

未定义索引：在第4行的C:\wamp\www\includeindex.php中提交

if ($_POST['submit'] != "") {
    if ($_POST['name'] != "") {
        session_start();
        $_SESSION['name'] = $_POST['name'];
        TopNavigation("PHP Includes Example - ECA236", "PHP Includes", $_SESSION['name']);
    } else {
        header("Location:includindex.php");
        exit;
    }
} else {
    TopNavigation("PHP Includes Example - ECA236", "PHP Includes");
    echo "<div class=\"formtable\">\n";
    echo "<br>";
    echo "<form action=\"" . $PHP_SELF . "\" method=\"post\">\n";
    echo "Please enter your name:<input type=\"text\" name=\"name\">\n";
    echo "<input type=\"submit\" class=\"btnSubmit\" value=\"Enter\" name=\"submit\">\n";
    echo "</form>\n";
    echo "<br>";
    echo "</div>\n";
    Footer();
}

?>

警告：include（include/header.php）[function.include]：打开流失败：第3行的C:\wamp\www\about.php中没有这样的文件或目录警告：include（）[function.include]：在第3行的C:\wamp\www\about.php中打开“include/header.php”进行包含（include_path='；C:\php\pear'）失败

致命错误：在第9行的C:\wamp\www\about.php中调用未定义的函数TopNavigation（），

TopNavigation（）函数中的所有echo
语句仍被错误引用。而不是\“n；
，它们应该以\n”结尾
//错了
echo“这里有一点关于我的。我是一个9岁双胞胎女孩的母亲；
//应该是：
echo“这里有一点关于我。我是一个9岁双胞胎女孩的母亲”\n”；
---^^^^
在php.ini中，将display\u errors=Off更改为display\u errors=On
似乎是为了跟进？
