Better template eval'ing

PHP Code:


		
			
function evaltemplate($templatename, $storagevar)

// evals $templatename and stores the output in $storagevar

{

    $localcopy = gettemplate($templatename);

    eval("\$$storagevar = \"$localcopy\";");

}

...and after that, I run:

PHP Code:


		
			
evaltemplate("templatename", "contentsvariable");

Finally, I put $contentsvariable at the top of the header. The template templatename exists. However nothing shows up in the header. Why?

Okay, I added this to the beginning of the function:

PHP Code:


		
			
    eval("global \$$storagevar;");

...and it's loading the template. However variables in the template aren't getting parsed due to the same variable scope issue.

Is there some way to make a function always modify global variables instead of local ones while at the same time not having to type global $varname; for each one?

you can just do something like:

PHP Code:


		
			
eval( generate_eval_code('template_name') );

Well maybe not as lengthy, but the idea is there.

Hmm, good point, although I'd prefer something function-based for simplicity.

I searched on php.net for a way to basically ignore variable scope in functions and make every variable global but didn't get anything working.
