Question

与PHP DOM合作——超文本处理。

2个问题

Recently read that, there is better way to output special html characters (e.g. ©): DOMDocument::createEntityReference() method. Main advantage is, you don t need to use htmlentities, it will be automatically escaped. For ex: $copyright_symbol = $document->createEntityReference("copy");. Now, the problem is, where can I find characters code reference? In my case I need php equalent of × (× symbol)
What if I want to set muliple classes to element? Can I do it like that $el->setAttribute( class , class1 class2 ... ) ??

Answer 1

here you can see character codes as well as friendly names. For your &#215, you will use "times" and for the second question, yes, you can do it like that.
