Much better to use a *function* which is parsed once than include()ing or eval()ing the same code over and over to (possibly) be re-parsed. It just makes more sense code structure-wise as well. > I did a benchmark between using include(), eval(), smarty, pattemplate, and > a few others and include() and eval() are always the fastest. > > Really depends upon what kind of features you need and what you consider > "evil". ;) By evil I mean that it's used for the wrong purposes much of the time. People aren't aware of the capabilities of the language or are simply ignorant of good coding style and use eval because it's easy. Heck, I used eval before I knew how to use $$ and arrays effectively. Here's a quote that really says it well: If eval() is the answer, you're almost certainly asking the wrong question. -- Rasmus Lerdorf, BDFL of PHP > > ---John Holmes... > -- DB_DataObject_FormBuilder - The database at your fingertips http://pear.php.net/package/DB_DataObject_FormBuilder paperCrane --Justin Patrin--
