false输出sql数据库substr_count

Question

what is my mistake?

$abfrage = "SELECT Antwort FROM EINTRAGEN";
$ergebnis = mysql_query($abfrage);
while($row = mysql_fetch_object($ergebnis))
{
$myString = "$row->Antwort";
$substr = "Ja";
$count = substr_count($myString, $substr);
echo $count;
}

The content of my database "Antwort" is: Nein, Ja, Nein

My problem ist, that the content of $count "0 1 0" is - why not only "1"?

Answer 1

Because substr_count is returning always an integer

echo $count ? $count : '';
