PHP braces { } replace <?php ?>?

I've seen in someones source code they load template.tpl and inside is ...value="{$开发者_运维技巧phcode}"... does {$phcode} replace <?php $phcode ?>

I don't find any reference in php manual.

A .tpl file isn't a PHP file and isn't parsed by the PHP engine. I'd guess you're looking at a Smarty template.

For the record, <?php $phcode ?> does nothing. You are probably thinking of either <?php echo $phcode ?> or <?= $phcode ?>, either of which is pretty close to exactly what Smarty does with that piece of code, yes.

Most likely it is Smarty template.

It's not PHP, it's using a templating language like Smarty.

I'm pretty sure that's the Smarty PHP templating engine. It can do stuff like that, it makes templating easier with the integrated php execution.

No, {} doesn't replace <?php ?>, at least not as far as the PHP language is concerned. It's possible that your template engine searches for things inside {} and then passes them to eval().
