fgetcsv does NOT get the cells right if the last characte from a cell is \
How to replicate:
//you can also try this with fopen('file.csv')
$body = "\"cell1\",\"cell2\\\",\"cell3\",\"cell4\"";
$filename = 'data://text/plain;base64,'.base64_encode($body);
$fp = fopen($filename,"r");
$a = fgetcsv($fp,10000,',','"');
print_r($a);
This will output
Array
(
[0] => cell1
[1] => cell2\",cell3"
[2] => cell4
)

Sounds reasonable to me. It probably wouldn't hurt to allow the enclosure to
accept an empty string as well.
I'll cook something up for trunk and we can decide whether we want this in 5.3
from there.

Description:
------------
Currently fgetcsv() gives a warning if the escape parameter is set as an empty
string (and the default is a backslash). I have some data that has backslashes
in it and it's not an escape character. Even though most of the times fgetcsv()
reads the data correctly, there is a little chance it will do it wrong if a
backslash is the last character of a multiline cell, which is usually stored
like this:
"\\\line1
line2\\\"
In order to fix that I supply chr(8) as an escape character because I know for
sure the data does not have the character. And if I pass an empty string
instead fgetcsv() will give a warning and refuse to read a line.
I suggest that fgetcsv() does accept an empty string as an escape and do no
escaping in that case, which is quite usual.
For ex., a MySql statement "Load Data Infile ... Into Table" has it as "Escaped
By None" to achieve the same result.
Test script:
---------------
if (!$Handle=fopen("sites.txt", "rb")) return false;
print_r(fgetcsv($Handle, 0, "\t", '"', ""));
fclose($Handle);
Expected result:
----------------
array( ... ) - depends on the input file
Actual result:
--------------
Warning: fgetcsv(): escape must be character in ...
