Using eval within Wordpress for a function mixed with html

Hi
I want to evaluate the string below within myfunc() and return a result ready to drop into my home page (echo $s;) For reasons I won't bore you with I want to store this fragment in a text file. Have bashed my head with all sorts of variants, but cannot get eval() to work! The bit that works directly in a page is this: '<a rel="external nofollow" href="'.get_bloginfo('wpurl').'/juniors/mirror"><img src="/oldsite/images/junior/.thumbs/.mirror.jpg" alt="mirror.jpg" title="mirror.jpg" width="95%" /></a> <hr />'; How to use eval() to get the proper result from this type of thing: Assuming I read the above fragment from a text file into variable $s function myfunc($s) eval('\$theresult= \$s;') return $s; So any help would be MUCH appreciated! Best regards from the UK!

True - I just quoted what I want as a final evaluated result. eval
assumes the string is php code, and html can be added by dropping out of php , like $s= 'echo "hello";?> html here '; eval($s) but it doesn't like function bloginfo('wpurl') and doesnt like angle brackets in the html much either.

Yes, quite right Otto,
I simplified it for the post and inadvertantly altered it in theprocess - I am indeed returning $theresult in the actual code I am trying out. The key thing is how to eval() a mixture of php and html to get same result as if it was put straight into a php page. I saw on php lots of discussion of eval(), and different ideas, but also comments that none of them worked properly, so thought would ask on the hackers list. just to re-iterate: this following type of code works straight in a page, <a rel="external nofollow" href="'.get_bloginfo('wpurl').'/juniors/mirror"><img src="/oldsite/images/junior/.thumbs/.mirror.jpg" alt="mirror.jpg" title="mirror.jpg" width="95%" /></a> <hr /> so what should it be so that I can pull it in from a text file, or a database, and then eval() it will give same result?

Why don't you just use sprintf?

good point on sprintf() - but assumes that I know the link will always
have the bloginfo() as the variable. I was trying to generalise it so that, for several records in a text file, it would do the whole thing! Thanks for suggestion Does anyone know hwo to combine php functions and html using eval?? I would still like to know.

Not having tested it, But going off what you originally posted:
function getStringFromFile($file) { $s = file_get_contents($file); eval('return ' . $s); } You need to combine the strings, not to insert one string inside the other i believe.

You're problem appears to be that you are programming when you should be
developing. Take for example your situation. You want a complex solution to a simple problem. If you were a developer, you would use the simple solution for the simple problem. The simple solution would be one that does not involve eval(). I think that if you gave us more code, we'd be able to get to the root of your problem and fix the cause instead of implementing something to cover it up.

Yeah, I gotta agree with Alan on this one. If you're reading a text
file and then eval()ing it, then that's basically the same as an include. Now, on the other hand, if you're eval()ing because you want the output back as a string, then the short answer is that you can't do that. eval() executes the code, and if that code makes output, then it makes the output. The returned result of the eval() call will be whatever that code in the string does as it's "return" statement. Output != returned data. You'd have to use an output buffer to grab the output from the eval(). ob_start() and such.
