No need to quote the *values*, they are sent as text. Not sure what 
you're doing with -alpha-, I assume it is a variable as well...

The safe syntax is

  echo "<iframe id=x1 
src='audiox1.php?asong={$number}&name={$alpha}'></iframe>";
 
> No need to quote the *values*, they are sent as text.

Utter nonsense.  Depending on the version of HTML and the attribute value, 
attribute values MUST be quoted.  The safe approach is to *always* quote 
attribute values, it certainly is when attribute values or parts of those 
are generated like here.  Since double-quoting is more common than single-
quoting, double-quoting as it was done by the OP actually is the safe 
approach.

You might have misread the original code, which is actually equivalent to

  echo '<iframe id="x1" src="audiox1.php?asong='
    . $number
    . '" name="alpha"></iframe>';

if we assume that the line-break after “$number.'"” was accidental 
originally or was inserted when you quoted the original code.

In particular, in your code the value of $alpha must be *URI-encoded* or the 
URI-reference that is the attribute value is invalid or the entire HTML 
fragment could become invalid (or code-injected) if $alpha contains space or 
special characters.  Other generated attribute values, unless it is certain 
that code injection is impossible (for example with int values), SHOULD be 
htmlspecialchars()'d.

Does it look like one?  RTFM.

Actually, that is the safe *PHP* syntax (after the line-break is removed).  
HTML requires another change:

  echo "<iframe id=x1"
     . " src='audiox1.php?asong={$number}&amp;name={$alpha}'></iframe>";

AISB, conversion of ”&” to “&amp;” or &#38; can and should be done with 
PHP's htmlentities() or htmlspecialchars(), respectively.  And “echo” should 
not be used like above, but like below:

  <iframe id="x1" src="audiox1.php?asong=<?php echo $number; 
?>&amp;name=<?php echo htmlspecialchars($alpha); ?>"></iframe>

PHP 5.4 and PHP < 5.4 with corresponding php.ini configuration support

  <iframe id="x1" src="audiox1.php?asong=<?= $number ?>&amp;name=<?= 
    htmlspecialchars($alpha) ?>"></iframe>

and

  <iframe id="x1" src="audiox1.php?asong=<%= $number %>&amp;name=<%=
    htmlspecialchars($alpha) %>"></iframe>
  
respectively.  Usually you would use a template engine or the MVC pattern:

  <iframe id="x1"
          src="audiox1.php?asong=<?= $this->number ?>&amp;name=<?=
            $this->escape($this->alpha) ?>"></iframe>

This is explained and recommended in the first chapter of the PHP manual.

BULLSHIT!
target="alpha" is a valid attribute, it is not a value.
And there is no $ needed in the values section.

   What in the world are you talking about? This has nothing to do with 
the -target- attribute. You said 'At least the first number is now 
displayed.' so I thought you would eventually substitute "alpha" with 
some variable content so I suggested it that way, also fixing your URL 
by adding the '&' between them.

It is a Valid attribute with a value specified.

What is the “values section”?

You would use “target="alpha"” to display the result of navigation or form 
submission in an “iframe” element with “name="alpha"” instead of the source 
window, as the OP apparently intended.  ISTM you need to brush up on your 
HTML knowledge quite a bit.

Norman, you've become confused by Richard's string quoting.

His php strings are single quoted and he uses double quotes for his html.

This means that php variable translation does not take place in the 
strings.

In his initial example, name="alpha" was an attribute of the iframe, not 
part of the query string of the src url.

This is why he has to replace songid with

'.$songid.' 

instead of 

$songid

Initially he said he was using this:

<iframe id="x1" src="audiox1.php?asong=songid" name="alpha"></iframe>

But he typically omitted to tell us whether this was in a heredoc or echo 
with single quoted strings (or even a nowdoc).

In a heredoc, he could use $songid ( or even {$songid} ) but if it was an 
echo with single quotes, he would need to use '.$songid.'

Subsequently he said '.$songid.' worked, so I deduce backwards from that 
that richard was using single quoted php string with echo.

This is an example of classic richard, he feeds you half the problem and 
the nature of the original problem only becomes clear after you've solved 
for all possible variations and he's picked the solution that works. It 
would be so much easier if he would learn to ask the right question, but 
that's probably a lost cause now.

Mind you, I suspect so is his website. I still haven't worked out what 
niche he expects to fill that isn't already fully covered by a 
combination of you tube and wikipedia.

   Yes, I actually see that now, but then again I usually keep my -id- 
and -name- attributes together at the beginning of a tag. Is it required 
no, but it sure does make for a bit of consistency when I'm looking for 
bugs in the same typical places for the same types of data. It was a 
misunderstanding on my part. As a general rule I shy away from doing a 
lot of concatenation and "\" escaping as much as I possibly can. I also 
try to sway others from it as well but, to each their own. It makes code 
painful to debug.
