1.strip_tags() function: can filter out HTML and PHP tags and return a brand new string!
Usage:
string strip_tags (string string to be processed [, string tags to be retained])
For example: For tags, write it like this, strip_tags($str, “”). If you want to keep multiple tags, separate them with spaces.
2. Use strpos and substr for mixed processing
When the string we want to intercept has a unique identifier, we can usually use this method, such as taking a label abc with a unique id. As long as we find the and, all the content in the middle will come out.
3.PHP DOMDocument
