PHP fopen（）工作不正确

Question

I try to open a file but output of file is not correct,because output is half-part of data in a file. I don't know solutions to resolve this problem

  <?php
    $handle = fopen("data/weather.arff", "r");
            while ($buffer = fgetc($handle)) {
                $result .= $buffer;
            }
    echo $result;
  ?>

Answer 1

I don't know Why I couldn't comment.(maybe lack of reputation). Have you used the "b" binary mode?!
Like this:

<?php
$handle = fopen("http://www.example.com/", "rb");
$contents = '';
while (!feof($handle)) {
  $contents .= fread($handle, 8192);
}
fclose($handle);
?>

Source function.fread
