尝试这个 ：

<?php
$page = "";
if(isset($_GET["page"]) && $_GET["page"] != "") {
$page = $_GET["page"];
}
?>

<div class="container">
<nav class="navbar navbar-inverse">
    <div class="container-fluid">
        <div class="navbar-header">
                <a class="navbar-brand" href="/womsy/home.php">Womsy</a>
        </div>
            <ul class="nav navbar-nav">
                <li <?php if ($page == "home") { echo "class='active'";} ?>><a href="?page=home">Home</a></li>
                <li <?php if ($page == "blog") { echo "class='active'";} ?>><a href="?page=blog">Blog</a></li>
                <li <?php if ($page == "projects") { echo "class='active'";} ?>><a href="?page=projects">Projects</a></li>
                <li <?php if ($page == "contact") { echo "class='active'";} ?>><a href="?page=contact">Contact</a></li>
                <li <?php if ($page == "about") { echo "class='active'";} ?>><a href="?page=about">About</a></li>
            </ul>
    </div>
</nav>

你需要修复你的if块

if ($page = "home")

至

if ($page == "home")

---

我认为你有一个错误

<?php if ($page = "home") {class=active;} else {echo "Failed to load active class."} ?>

应该

<?php if ($page == "home") {class=active;} else {echo "Failed to load active class."} ?>
