fgetcsv seems to handle newlines within fields fine. So in fact it is not reading a line, but keeps reading untill it finds a \n-character that's not quoted as a field.
Example:
<?php
$handle = fopen("test.csv", "r");
while (($data = fgetcsv($handle)) !== FALSE) {
var_dump($data);
}
?>
Returns:
array(3) {
[0]=>
string(5) "col 1"
[1]=>
string(4) "col2"
[2]=>
string(4) "col3"
}
array(3) {
[0]=>
string(29) "this
is
having
multiple
lines"
[1]=>
string(8) "this not"
[2]=>
string(13) "this also not"
}
array(3) {
[0]=>
string(13) "normal record"
[1]=>
string(19) "nothing to see here"
[2]=>
string(7) "no data"
}
This means that you can expect fgetcsv to handle newlines within fields fine. This was not clear from the documentation.
