[PHP] How to print variable name and contents

[nntp.charter.net]

I want to write a trace procedure and call it with variable names, and I am 
having trouble with the syntax.  My goal is to have a procedure that will 
echo lines such as:

Trace: $myvar="the contents of $myvar

My attempt that didn't work is to write a function:

function my_trace($m){
   echo ("\n<br>TRACE: $m = ");
   eval("\$t=\"$m\";");
   echo($t."<br>\n");
 }

and call it with statements like:

my_trace("\$my_var");
my_trace("\$_ENV[\"COMPUTERNAME\"]");

What am I doing wrong, and how should this be done?  Also, should I post to 
a different group?

Thanks,
Gil Grodsky
