我现在就用PHP读取这个记事本，因为这个里有好段，每段前都有一个标题，我现在就想通过前面的标题，读取出不同的内容。


请高手给出指教。

逻辑不对，[email protected]
修改如下：

PHP code

";        echo $buffer."
";    }else{        echo "This is body
";        echo $buffer."
";    }}fclose($fp); //关闭文件流?>
------解决方案--------------------
[email protected]，用这个来分隔，注意 @ 要顶格

PHP code

$find = 'about'; //要找的标题$file_name="dir.txt";  $fp=fopen($file_name,'r');$title = '';$content = '';while($buffer = fgets($fp,1024)) //文件不一定要读完{  if($buffer{0} == '@') { //检查是否为标题    if($title == $find) break; //是要的则退出    $title = trim($buffer, '@'.PHP_EOL); //保存标题    $content = ''; //清空内容  } else $content .= $buffer; //保存内容}fclose($fp); //关闭文件流echo content."
";
------解决方案--------------------
如果标题有固定规律的话,读一行,然后检查是不是标题

比如这一行要没有空格 长度少一多少 等等
