<?php
$myfile = fopen("include/webdictionary.txt", "r") or die("Unable to open file!");

// Output one line until end-of-file
while(!feof($myfile)) {
  echo fgets($myfile) . "<br>";
}
fclose($myfile);
?>

• The feof() function checks if the "end-of-file" (EOF) has been reached.
• The feof() function is useful for looping through data of unknown length.
• The example above reads the "webdictionary.txt" file line by line, until end-of-file is reached.
