PHP - If string contains '<' or '>' - strpos()

Question

I want to do a simple kind of test to see if a string contains any HTML.

In this case if the $string variable is test or <test> it returns no for me:

$string = 'test';
if(strpos($string,'<') !== 'false'){
    echo 'no';
}else{
    echo 'yes';
}

Is there a better way to check if a string contains HTML? I don't want to do anything to the string just check if it has HTML tags?

I think you should use an HTML Parser. '<' is not mandatory a HTML tag. — Jens, Aug 13 '18 at 11:08
@Jens I think you'll find the < is pretty much mandatory when opening any html tag — Dale, Aug 13 '18 at 11:10
@Dale yes, but the presence of `<` doesn't guarantee the string contains HTML. — BenM, Aug 13 '18 at 11:10
ah I see your point, though you would surely use < in your edge case example — Dale, Aug 13 '18 at 11:11
