I have a code where a csv file is uploaded ,the data is extracted from it and uploaded to database.Everything works fine,but how can i skip the empty rows and continue reading the rows with data in it.
This is the code where i extract data from csv file
if (($source = fopen( $csv_file, "r")) !== FALSE)
{
//read data from excel
while (($data = fgetcsv($source, 1000, ",")) !== FALSE)
{
$question=$data[0];
$point=$data[1];
$header=$data[2];
$footer=$data[3];
$type_value=$data[4];
$group_name=$data[5];
echo $question;
}// while end
}

if ($data[0] == NULL)
continue;
This is because fgetcsv returns a non-empty array with a null element inside.

If you use PHP's SplFileObject instead of the basic fgetcsv() function, it has built-in options to skip empty lines:
$file = new SplFileObject($csv_file);
$file->setFlags(SplFileObject::READ_CSV SplFileObject::SKIP_EMPTY | SplFileObject::DROP_NEW_LINE);
foreach ($file as $data) {
...
}

Try this
if (($source = fopen( $csv_file, "r")) !== FALSE)
{
// read data from excel
while (($data = fgetcsv($source, 1000, ",")) !== FALSE)
{
if ((string) $data[0] != '0' and empty($data[0]))
{
continue;
}
$question = $data[0];
$point = $data[1];
$header = $data[2];
$footer = $data[3];
$type_value = $data[4];
$group_name = $data[5];
echo $question;
}
}

Try it with
if ($data === null) continue;
I didn't test it, but I sthink it should work.
