Convert windows newlines to unix newlines

This tutorial will show you how to convert windows system newlines
in UNIX system newlines. I hope will help you.

Here is some script from real live

This PHP Script allows you to upload a text file in with windows newline
characters, it wil then remove the "/r" char and output the newtext file to the browser.

   
<?php    
if ($_FILES['parse_file'] != "") {
    
    $file = file($_FILES['parse_file']['tmp_name']);
    $counter = count($file);
    $fp = fopen('newtext.txt', 'w+');    
    for ($x=0; $x <= $counter; $x++)
    {                            
        if(stristr($file[$x], "\r"))
        {
            fputs($fp, str_replace("\r", '', $file[$x]));
        }                    
                        
    }
    header('Location: newtext.txt');
    
} else {
    ?>
    <form enctype="multipart/form-data" method="post" action="#">
    <input type="hidden" name="MAX_FILE_SIZE" value="25000">
    <p><strong>File to Upload:</strong><br>
<input type="file" name="parse_file" size="30"></p>
<input type="submit" name="submit" value="submit">
</form>
   <?php        

}
?>
