title: Eliminating carriage returns from a CSV file in PHP
body: <p>I'm trying to write a php file to eliminate carriage returns in a CSV file.  I am trying to first read from the original CSV file containing the carriage returns in column 1.  Next, trim or eliminate the carriage returns and then write the corrected string into a new CSV file. But I'm having some trouble on how to specifically do that. I received an error on this program and I'm not sure what's the problem with this code.
  What am I missing here?  Any suggestions?</p>
  
  <p>Here is my original code:</p>
  
  <pre><code>&lt;?php
  $file_read = fopen('testCarriageFile.csv', "r");
  $file_write = fopen('testCarriageFile2.csv', "w+");
  while(!feof($file_read)) {
      $file_trim = trim($file_read, "\r");
      fwrite($file_write, $file_trim);
  }
  fclose($file_read);
  fclose($file_write);
  ?&gt;
  </code></pre>
