【问题描述】：

在我正在处理的网站中，我包含页眉和页脚。我希望能够在网站的每个页面上使用不同的元描述，但这让我感到困惑。标题工作正常，但我想知道这是否是因为涉及引号。

header.php 代码为：

<!DOCTYPE html>

<head>

<meta charset="UTF-8">  
<title><?php echo $title; ?></title>
<meta name="description" content="<?php echo $desc; ?>">
<meta name="keywords" content="neurologist, neurologic, neurology, nervous system, brain, seizure, epilepsy, carpal tunnel, seattle, ballard, washington, wa, king county, swedish hospital">

index.php 代码是：

<?php include ("header.php"); ?>
<?php $title = "Neurologic Clinic | Dr. Hal Rappaport | Seattle Neurologist"; ?>
<?php $desc = "Dr. Hal Rapport is a neurologist located in Seattle's Ballard neighborhood. He specializes in neurologic conditions and disorders and is also a certified psychologist"; ?>

感谢您提供的任何帮助。

【问题讨论】：

在您分配给$title和$desc的标题之后包括

标签： php html include

【解决方案1】：

这是因为你在包含头之后分配你的变量，所以改为

<?php $title = "Neurologic Clinic | Dr. Hal Rappaport | Seattle Neurologist"; ?>
<?php $desc = "Dr. Hal Rapport is a neurologist located in Seattle's Ballard neighborhood. He specializes in neurologic conditions and disorders and is also a certified psychologist"; ?>
<?php include ("header.php"); ?>

【解决方案2】：

首先，定义 $title、$desc。然后包含标头

<?php
    $title = "title";
    $desc = "description";

    include("header.php");
?>

【解决方案3】：

您无需在每一行中都调用<?php ?>。

<?php
$title = "Neurologic Clinic | Dr. Hal Rappaport | Seattle Neurologist";
$desc = "Dr. Hal Rapport is a neurologist located in Seattle's Ballard neighborhood. He specializes in neurologic conditions and disorders and is also a certified psychologist";
include ("header.php");
?>
