Replace by nothing and remove the line

In a file, I replace a marker !!marker!! by a string or nothing:

if ($foo){
        insert_content('index.html', 'index.html', '!!marker!!', $string);
    }else{
        insert_content('index.html', 'index.html', '!!marker!!', '');
    }

…but as !!marker!! was on its own blank line, this line remains, and blank.

Is it possible to replace the marker by nothing and remove the line it was on?

[^\n]*!!marker!![^\n]*\n

This should remove the line .Replace by empty string.See demo.

$re = "/[^\\n]*!!marker!![^\\n]*\\n/im";
$str = "asdasdasd\nsadasd !!marker!!a asdasd\nklklkl\na\nsd\nas\nd\n";
$subst = "";

$result = preg_replace($re, $subst, $str);
