文本文件 - 定义占位符，通过PHP读取 - 在网站上生成HTML/CSS

您需要解析文件的内容：

<?php
$tokens = array(
  'title'    => array('type' => 'multi-line', 'tag' => 'h1'),
  'break'    => array('type' => 'single',  'tag' => 'br'),
  'headline' => array('type' => 'single',  'tag' => 'hr')
);
$currentToken = null;
// Loop
foreach (file('input.txt') as $line) {
  if(strlen($line)==0)//empty case
    continue;
  //check tags
  if(preg_match('/[(w+)]/', $line, $match)){
    if(isset($tokens[strtolower($match[1])])) {
      //multi-line case
      if($currentToken != null and $currentToken['type'] == 'multi-line') {
        echo "</{$currentToken['tag']}>"; //close multi-line Tag
      }
      $currentToken = $tokens[strtolower($match[1])];
      //single and multi-line
      echo ( $currentToken['type'] == 'single')?
        "n<{$currentToken['tag']}/>": // print a single tag
        "<{$currentToken['tag']}>"     //open multiline tag
      ;
    }
  } else {
    echo $line;
  }
}

<?php
$fp = fopen('/tmp/test.txt','r');
while(!feof($fp))
{
    $content = trim(fgets($fp,4096));
    if(!$content) continue;
    //see if this is a tag? if it is, set the tag name;
    if(preg_match('/[(w+)]/', $content,$match))
    {
        $tagname = $match[1];
    }
    else//if it is not a tag,then its the content.
    {
        $tagname = $tagname ? $tagname : 'div';
        echo "<{$tagname}>{$content}</{$tagname}>n";
    }
}
