[PHP] interpreting variables containing in another variable

[ROBERT MCPEAK]

I've got a variable - $email_body, that contain's other variables.  For example, echo 
$email_body, might look like this:

$name, $address, $phone, $blah


I want those variables to interpreted with corresponding values set earlier in the 
script.  So, in effect, where name=bob, address=101 east main, phone=555-, and 
blah=foo, echo $email_body would look like this:

bob, 101 east main, 555-, foo


Any suggestions?

Thanks in advance.

-Bob

Not sure what your saying, but like:

$email_body = $name . ,  . $address . ,  . $phone . ,  . $blah;

?

Check out the eval() function:

http://www.php.net/manual/en/function.eval.php

Also, you might want to consider altering your approach slightly. For
example, maybe something like this would be more appropriate:

$email_body = $name, $address, $phone, $blah;

If you echo $email_body in this case, it will output:

bob, 101 east main, 555-, foo

Good luck.

That's what eval() is for. eval() evaluates syntactically correct PHP code.

What you need to do is

$email_body = str_replace('', '\', $email_body);
global $php_error;
$php_error = null;
@eval(\$email_body = \$email_body\;);
if ($php_error) die ($php_error);

Of course all double quotes need to be escaped beforehand, as the example
shows. The error handling here is somewhat useless but demonstrates the idea.
