That is as expected, you're setting the value of asong in the query
string to the text value songid.
Depending on how you're generating the string:
<iframe id="x1" src="audiox1.php?asong=songid" name="alpha"></iframe>
and assuming that $songid is a php variable containing the numeric songid
that you want to pass, you may wish to replace songid in the above
construction with one of:
' . $songid . '
$songid
{$songid}
I also suggest that you read
http://www.php.net/manual/en/language.types.string.php
very carefully. There are some very important comments there about what
happens inside different types of string literal depending on the quoting
methods used.
