Ok, I can live with the embedded newlines in fgetcsv even though I think it is wrong. No other app will read a csv file this way. MySQL for example exports a literal \n for newlines and translates them on import rather than embedding them.
But, I do think the length should be respected no matter what:
data:
-----------------
6,7,8,line1
1,2,3,"line2
2,4,5,line3
2,4,5,line3
2,4,5,line3
2,4,5,line3
2,4,5,line3
2,4,5,line3
2,4,5,line3
2,4,5,line3
2,4,5,line3
2,4,5,line3
2,4,5,line3
2,4,5,line3
2,4,5,line3
2,4,5,line3
2,4,5,line3
script:
---------------
$fp=fopen("test.csv", "r");
while($line=fgetcsv($fp, 24)){
print_r($line);
}
Nothing after that quote gets read. Even after 24 bites have been read.
It would seem to me that the code which reads an additional line if an embedded newline is reached should not issue an FP_FGETS with len but should use len-strlen(temp). This would make the length param make more sense. And then if len was met it should terminate the record and start all over.
The code in this function is less that understandable with all the great names like buff and temp floating around. I tried looking at it but will leave it to the guys who wrote it.
