Question

Working with PHP DOM – HTML manipulation.

Got 2 questions

1. 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)
2. 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.
