CURL doesn't return any output when reading URL

I am reading a CSV file which contain URLs. I am trying to output the result of those URLs but facing strange issue. I can't seem to understand why this code doesn't print variable $output when you try to print item which is on first line.

This is my CSV file containing two records:

www.serverfault.com
www.stackoverflow.com

This is my code

<?php
$myfile = fopen("products.csv", "r") or die("Unable to open file!");

    while(!feof($myfile))
    {
        $myline = fgets($myfile);

        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $myline);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        $output = curl_exec($ch);
        curl_close($ch);

        if($myline == "www.serverfault.com")
        {
            echo $output;
        }
    }
?>

Notice in CSV file the first record is www.serverfault.com and it never prints the $output. If I move this record to second line then it prints $output but then it doesn't print $output for www.stackoverflow.com which is on first line now.

What's going on?

You're just assuming success. curl_exec returns boolean false on failure, which prints as a zero-length string.

Add this:

if($output === false) {
     die(curl_error($ch));

}

And don't forget to check for whitespace (e.g. linebreaks) on your string. Your $myline might actually be www....com\n or similar.
