Auto populate if row isn't long enough

[Blackhawkso]

I am having to ingest a CSV that is created by an external source and all but the last row has 4 sections.

Foo,Bar,Baz,Pineapple
Foo,Bar,Baz,Pineapple
Foo,Bar,Baz,Pineapple
*END*

Unfortunately the external system signs off the end of the file with

*END*

Is there a way that I can tell your code to just add blank fields to the end to give it the correct amount of fields so the file can be processed?

Hmm.. The code uses fgetcsv and fputcsv. So, consumption of such a file should not be an issue. Then, the final task is to delete the last line from the generated csv. This can be accomplished like so:

$filename = 'foo_bar.csv';
$arr = file($filename);   //read the file into an array
array_pop($arr);          //remove the last element
file_put_contents($filename, $arr);  //write back

Please let me know if I misunderstood your requirements.
