Detect HTML tags in a string

Question

I need to detect whether a string contains HTML tags.

if(!preg_match(\'(?<=<)\\w+(?=[^<]*?>)\', $string)){ 
    return $string;
}

Answer 1

you need to 'delimit' the regex with some character or another. Try this:

if(!preg_match('#(?<=<)\w+(?=[^<]*?>)#', $string)){ 
    return $string;
}
