Try this ... is not really a bug because a "_" can be part of a variable-name.

$var1="1";
$var2="2";

echo "$var1-$var2". "\n<br>";
//delivers: 1-2

echo "$var1_$var2" . "\n<br>";
//delivers: 2 ????????????????

echo "$var1\_$var2". "\n<br>";
//delivers: 1\_2

Yes, exactly: this is not really a bug because a "_" can be
part of a variable-name.
