QUESTION external text file

[jwzumwalt]

A complete example would be...

PHP Code:

<?php


  $filename = "test.dat";
  
  while (1) {
    $filecontents = read_file($filename);
    $content = htmlspecialchars($filecontents, ENT_COMPAT, 'utf-8', false);
    echo $content;   
    flush();
    ob_flush();    
    sleep(60);  // read temperature every 60 seconds
  }

  /* +-------------------------------------------------------+
     |                  read file - function                 |
     |  file can be any qualified path including web urls.   |
     |  $filename = "http://www.example.com/some/file.txt"   |
     +-------------------------------------------------------+ */    
  function read_file($filename) {
    if (file_exists($filename)) {
      $filedata = file_get_contents($filename);
      return $filedata;
    } else {
      echo "File not found";
    }
  }

?>
