One bug in LWC's strip_tags function:
You must add a U option in the preg_replace to have it work when stripping content :

$str = 'test : <tag>blah</tag> hello <tag>blah</tag>';

$b = strip_only($str, 'tag', true); 
will return "test : " without the U option
and return "test : hello" with it.

function strip_only($str, $tags, $stripContent = false) { 
    $content = ''; 
    if(!is_array($tags)) { 
        $tags = (strpos($str, '>') !== false ? explode('>', str_replace('<', '', $tags)) : array($tags)); 
        if(end($tags) == '') array_pop($tags); 
    } 
	
	if ($stripContent) 
	    foreach($tags as $tag)
			 $str = preg_replace('#<'.$tag.'[^>]*>.+</'.$tag.'[^>]*>'.'#isU', '', $str); 
	else 
	    foreach($tags as $tag) 
			 $str = preg_replace('#'.'</?'.$tag.'[^>]*>'.'#is', '', $str); 
	
    return $str; 
}
