PHP; assigning fgets() output to an array

问题

I am attempting to assign the string returned by the fgets() function to an array in PHP. I have tried test strings and they work fine. I have also made sure that fgets() is returning items, but still no joy. Thinking that it may be a timing issue, I had the function run onload and that didn't work. My code is below; any help on this would be much appreciated.

function createDataArray()
    {
        global $resultsArray;

        $i = 0;
        $file = fopen("downloads/E0.csv","r");

        while(! feof($file))
        {
            $line = fgets($file, 4096);
            $resultsArray[$i] = $line; //This isn't working. Something is wrong with $line. It is a string, but it doesn't get assigned to the array.
            $i = $i + 1;
        }
        fclose($file);
    }

回答1:

PLEASE return the array; do not use globals.

This fix should work:

function createDataArray()
    {
        $resultsArray = array();

        $file = fopen("downloads/E0.csv","r");

        while(! feof($file))
        {
            $line = fgets($file, 4096);
            $resultsArray[] = $line; 
        }
        fclose($file);

        return $resultsArray;
    }
