php - fgetcsv() notice: "escape must be a single character" with 'µ'


When I usefgetcsv() withescape =µ like this

$filename = 'test.csv';
$handle = fopen($filename, 'r');
$a = fgetcsv($handle, 0, ';', '"', 'µ');

php outputs a notice

Notice: fgetcsv() [function.fgetcsv]: escape must be a single character in myPhpFile.php on line 23





µ isn't a standard Ascii character. Which means that PHP sees it as an UTF-8 encoded character which are 16 bits while Ascii is 8 bits. Hence the multiple characters. You should use something else.
