Description:
------------
Hi.

The issue was initially caught when I used '\t' rather than "\t".

The source for fputcsv reports notices when you use a delimiter or an enclosure of > 1 character. But fgetcsv doesn't report this.

The following patch should fix this.

Reproduce code:
---------------
<?php
error_reporting(E_ALL);
++$dummy; // Proof of notices working.

// Store CSV like data in temporary file.
$fp = tmpfile();

// Real data I've been given - yeuch!
fwrite($fp,  <<< END_DATA

END_DATA
);

// Reset the file pointer.
fseek($fp, 0, SEEK_SET);

// Get data and report the number of 
$a = array
	(
	fgetcsv($fp, 8192, '``'), // Expect notice - php_error_docref(NULL TSRMLS_CC, E_NOTICE, "delimiter must be a single character")
	fgetcsv($fp, 8192, '`', '\t'), // Expect notice - php_error_docref(NULL TSRMLS_CC, E_NOTICE, "enclosure must be a single character");
	fgetcsv($fp, 8192, '`', '\t'), // Expect notice - php_error_docref(NULL TSRMLS_CC, E_NOTICE, "enclosure must be a single character");
	fgetcsv($fp, 8192, '`', '\t'), // Expect notice - php_error_docref(NULL TSRMLS_CC, E_NOTICE, "enclosure must be a single character");
	fgetcsv($fp, 8192, '`', "\t"), // Nothing wrong with this one.
	);
foreach($a as $b)
	{
	// Each row has 23 values.
	echo count($b), ' ', $b[2], "\n";
	}
fclose($fp);
?>

Expected result:
----------------
Notices about enclosure or delimiter not being a single character like fputcsv

Actual result:
--------------
