有几种不同的方式可以使用PHP显示html。通常,您将使用echo命令输出一些内容。这将被web浏览器看到,然后它将格式化它。

<?php get_header(); ?>

<div class="content">

    <div class="content_botbg">

        <div class="content_res">

            <!-- full block -->
            <div class="shadowblock_out">

                <div class="shadowblock">

                            <?php if ( !empty( $post->post_parent ) ) : ?>

打破 PHP 输出限制

除了使用 echoprint 等函数外,你还可以结束脚本,脚本结束后的所有内容将作为普通 HTML 输出到浏览器。你还可以在关闭 PHP 标签后随时重新启动脚本。是不是有点困惑?其实很简单。

假设你有一个 for 循环来输出从 1 到 5 的数字:

<?php
 
echo("<ul>");
for($x = 1; $x < 6; $x++)
{
  echo("<li>" . $x . "</li>");
}
echo("</ul>");
 
?>

虽然对于输出大量内容的较大页面,我通常会使用模板,但我们稍后会讲到。记得你所有的 PHP 脚本都是以 <?php 开头并以 ?> 结尾吗?这些标签并不一定要是文件的开头和结尾。实际上,PHP 处理结束和重新启动脚本的方式就像所有内容都位于 ?><?php 标签之间,并且这些内容都在 echo 语句内部一样。

因此,你可以做如下操作:

<ul>
 
 <?php
 for($x = 1; $x < 6; $x++)
 {
 ?>
  <li><?= $x ?></li>
 <?php
 }
 ?>
 
</ul>

这实际上是输出脚本中变量的一个非常常见的方法,特别是在变量周围有大量 HTML 的情况下。如前所述,我个人很少这样做,因为我认为对于较小的脚本,使用 echo 可以让代码更简洁(对于较大的脚本,我会使用模板)。然而,为了覆盖大部分语言功能,这也是你可以使用的另一种方法。
