You do not need regex for that
$string = '<h1>Title</h1>';
echo str_replace(['<h1>', '</h1>'], '', $string);

PHP preg_replace() - Unknown modifier
Hi everyone,
I have this string:
<h1>Title</h1>
<p>Body Text.</p>
And I want to get rid of the <h1> tag.
I created this RegEx:
<h1>(.+)</h1>
But this does not work:
preg_replace('<h1>(.+)</h1>', '', $string)
I get this error:
ErrorException: preg_replace(): Unknown modifier '('
What's happening here?
Thank you! Jeroen

@bugsysha No because I also want to get rid of the contents between the <h1> and '' tag

Your regex mislead me. Then there is no need for ( and ).
preg_replace('/<h1>.+</h1>/', '', $string);

This should work
preg_replace('/<h1>(.+)<\/h1>/gm', '', $string)

@michaloravec I get this error:
Unknown modifier 'g'
This is my code:
protected function parseMarkdown(string $markdown)
{
$converter = new CommonMarkConverter(); // the markdown parser class
$html = $converter->convertToHtml($markdown);
$html = preg_replace('/<h1>(.+)<\/h1>/gm', '', $html);
$this->html = $html; // $this->html is a public property
}

So remove it
preg_replace('/<h1>(.+)<\/h1>/', '', $string)
