PHP regex to match HTML tag names except some tags

I'm trying to match any open HTML tag except input tag using regular expression in PHP. Here is my pattern.

/<([a-z]+)([^>]*>)?/i

It matches all below:

<input type="text">
<img src=">
<a href="">
<button type="button"></button>
<div id="some"></div>
<p></p>

I don't want to match input. I may exclude more tags in the future as I stated some tags in my question title.

What I've tried so far

[Edit]

As per my example, I also want to keep the tag name only returned in the matched results, e.g, img, a, button, div, p, etc.

<(?:(?!input)[^>])*>(?:<\/[^>]*>)?

Try this.See demo.

https://www.regex101.com/r/fG5pZ8/13

$re = "/<(?:(?!input)[^>])*>(?:<\\/[^>]*>)?/im";
$str = "<input type=\"text\">\n<img src=\">\n<a href=\"\">\n<button type=\"button\"></button>\n<div id=\"some\"></div>\n<p></p>";

preg_match_all($re, $str, $matches);

Edit:

Use 

(?!<input)<([A-Z0-9a-z]+)([^>]*>)?

If you want to save tag separately.

Use a negative lookahead like (?!input\b):

<(?!input\b)([\w]+)([^>]*>)?

To exclude multiple tags, use (?!(?:tag1|tag2|tag3|...)\b)
