Modify as follows:

PHP code

  "; Echo $ buffer ."
";} Else {echo" This is body
"; Echo $ buffer ."
";}} Fclose ($ fp); // close the file stream?>

PHP code
   
   
$ Find = 'about'; // the title to be found $ file_name = "dir.txt"; $ fp = fopen ($ file_name, 'r'); $ title = ''; $ content = ''; while ($ buffer = fgets ($ fp, 1024) // The file does not have to be read {if ($ buffer {0} = '@') {// check whether the title is if ($ title = $ find) break; // if yes, exit $ title = trim ($ buffer ,'@'. PHP_EOL); // save the title $ content = ''; // clear the content} else $ content. = $ buffer; // save content} fclose ($ fp); // close the file stream echo content."
";
------ Solution --------------------
If the title is fixed, read a row and check whether the title is correct.

For example, the length of a line is less than one space.
