fgetcsv() Skip empty rows

[code green]

I am trying to skip empty rows in a csv file
The manual states

Note:
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.

But none of these tests seem to work.
Anybody know why
[PHP]while(($data = fgetcsv($this->handle)) !== false)
{
if(!is_null($da ta[0])) #no
if(!empty($data )) #no
if(!empty($data[0])) #no
{[/PHP] And variations thereof

Hi.

You are testing to see if there is a null, right?
That is, if the field is null, you want the if to evaluate true?
If so, why do you flip the result of the if statement?

Testing this on my own, the empty function worked perfectly.
Even a simple boolean check against the empty array element worked.

The is_null function doesn't work, however. This would be due to the fact that it apparently only checks for a variable set with the NULL constant, which the fgetcsv doesn't do for empty cells.

All of this worked for me:

if($_v == null)
if(empty($_v))
if(!$_v);
 

If that isn't working for you, could there be a problem with the CSV data?

Edit:
Ok, so I kind of missed the point there. Was thinking about empty cells :P

But, with completely empty rows, these three still worked for me:

if($data[0] != null) {
  # Show row
}
if($data[0]) {
  # Show row
}
if(!empty($data[0])) {
  # Show row
}

Thanks for the Edit. You nearly lost me there Atli.
Did some testing. These are the results

[PHP]FAILED
if(!is_null($da ta[0]))
if(!empty($data ))
if(($data))
if(!is_null($da ta))
if($data != null)

WORKED
if(!empty($data[0]))
if($data[0] != null)
if($data[0])
if(!empty($data[0])) [/PHP]
Conclusion
Looks pretty obvious that the first element must be tested.
The NULL value in element 0 means an empty element but a non-empty array.
I didn't realise this was the case.
Don't know whats going on with is_null

I suppose if($data[0] != null) is the safest to use just in case the first column of a row is empty.

ADDITION
[PHP] if($data[0] !== null)
if(!($data[0] === null))[/PHP] Don't work
