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。
------解决方案--------------------
逻辑不对,explode之后的数组元素是不包含@的
修改如下:
<?php $file_name="dir.txt"; $fp=fopen($file_name,'r'); while(!feof($fp)) //文件全部要读完 { $buffer=fgets($fp); //获得一行,不要加长度 if(preg_match('/\s*@/i', $buffer)){// 用正则 echo "This is title<br>"; echo $buffer."<br>"; }else{ echo "This is body<br>"; echo $buffer."<br>"; } } fclose($fp); //关闭文件流 ?> <br><font color="#e78608">------解决方案--------------------</font><br> //标题前加个@符号,用这个来分隔,注意 @ 要顶格<br><br>
$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."<br>"; <br><font color="#e78608">------解决方案--------------------</font><br>如果标题有固定规律的话,读一行,然后检查是不是标题<br><br>比如这一行要没有空格 长度少一多少 等等 <br><font color="#e78608">------解决方案--------------------</font><br>帮忙顶下....<br> <div class="clear"> </div>
