Question

I want to replace all html codes to empty space. I think I should use preg_replace function, but I’m not sure how should I do that in case when html codes looks in this way:

”
β

$text="β something ” test..."

$text=preg_replace("&# [what should be here?] ;", " ", $text);

echo $text;
result =  something  test...

I think it should be only numeric, because I found only numeric ones here: http://www.ascii.cl/htmlcodes.htm

You could look at strip_tags which does exactly that. However those arent HTML codes, they are called HTML entities.

The regex to match what you want looks like this:

(&#.+?;)

Its rather simple, look for the &# then any repeated character until ;.

Edit: As Qtax pointed out, they dont have to be numbers. Dot matches all.
