fgetcsv skip blank lines in file

Question

I have this script that I did, it basically grabs all the files in my "logs" folder and merge them all in one array file, my only problem is that, sometimes the script breaks if there is blank line or empty line! how can I tell it to automatically skip blank empty lines and go to next? blank lines are not necessarily at the top or bottom! could be in the middle of the csv file

<?php
    $csv = array();
    $files = glob('../logs/*.*');
    $out = fopen("newfile.txt", "w");

    foreach($files as $file){
        $in = fopen($file, "r");

    while (($result = fgetcsv($in)) !== false)

        {   
            $csv[] = $result;
        }

        fclose($in);
        fclose($out);
    }

    print json_encode(array('aaData' => $csv ));
?>

As you can read in the documentation for fgetcsv():

A blank line in a CSV file will be returned as an array comprising a single null field, and will not be treated as an error.

Checking for that before adding it to your data array should be sufficient:

while (($result = fgetcsv($in)) !== false) {
    if (array(null) !== $result) { // ignore blank lines
        $csv[] = $result;
    }
}
