由于HHVM不支持eval()，一直没找到好的方法。求教，有什么办法代替，或者修改好的朋友求教！

谢谢各位！

例如：
$template = preg_replace("/{{eval (.?)}}/ies", "\$this->stripvtag('<? \1?>')", $template);
$template = preg_replace("/{eval (.?)}/ies", "\$this->stripvtag('<? \1?>')", $template);

eval

template

stripvtag

hphpd> $string = 'cup';
$string = 'cup';
hphpd> $name = 'coffee';
$name = 'coffee';
hphpd> $str = 'This is a $string with my $name in it.';
$str = 'This is a $string with my $name in it.';
hphpd> echo $str. "\n";
echo $str. "\n";
This is a $string with my $name in it.

hphpd> echo $str. "\n";
echo $str. "\n";
This is a $string with my $name in it.

hphpd> eval("\$str = \"$str\";");
eval("\$str = \"$str\";");
hphpd> eval("\$str = \"$str\";");
eval("\$str = \"$str\";");
hphpd> eval("\$str = \"$str\";");
eval("\$str = \"$str\";");
hphpd> echo $str. "\n";
echo $str. "\n";
This is a cup with my coffee in it.

怎么不支持？
