php - Skip html tags when searching for whitespace -


i have line of code here , $post['post'] string may contain html tags:

echo mb_strpos(mb_substr($post['post'], 299), " ");

i want find first occurrence of whitespace character 299th offset of $post['post'], want ignore html tags. example, want ignore whitespace in following string:

<br />

how ignore whitespace inside such html tags?

you should use strip_tags (more info here: http://php.net/manual/en/function.strip-tags.php):

echo mb_strpos(mb_substr(strip_tags($post['post']), 299), " ");

if want allow html tags, can here:

echo mb_strpos(mb_substr(strip_tags($post['post'], "<a><b><span>"), 299), " ");
