不能在wordpress functions.php中使用php fopen()函数

I am trying to simple run fopen() in the functions.php, and have also tried it in a test.php wordpress template file.

But it does not work. If I move the test.php file and csv file to a location outside the theme folder then it works first time.

function csv_to_array($filename='', $delimiter=',')
{
    if(!file_exists($filename) || !is_readable($filename))
        return FALSE;

    $header = NULL;
    $data = array();
    if (($handle = fopen($filename, 'r')) !== FALSE)
    {
        while (($row = fgetcsv($handle, 1000, $delimiter)) !== FALSE)
        {
            if(!$header)
                $header = $row;
            else
                $data[] = array_combine($header, $row);
        }
        fclose($handle);
    }
    return $data;
}

echo '<pre>';
var_dump(csv_to_array('csv/nationality-codes.csv'));
echo '</pre>';

This is my folder structure in the theme file...

enter image description here

Any ideas why it does not work?

    You need to use the full file path instead of a relative one.

    Use the WordPress function get_template_directory() to get the path to your template directory. From there add the path to your file.

    Change:

    var_dump(csv_to_array('csv/nationality-codes.csv'));
    

    To:

    var_dump( csv_to_array( get_template_directory() . 'csv/nationality-codes.csv' ) );
