How can php or jquery find the html element that is not closed and add it to it?

?


Share :?? // This p is not closed


------ Solution --------------------
Read with DOMDocument: loadHTML and write it with DOMDocument: saveHTML
It is automatically completed, but note that the html document must have Flag. if not, add it by yourself.
For example, your section (assuming it is gbk) 
$ S = <HTML
// This p is not closed

$ Doc-> loadHTML ($ s );
Echo $ doc-> saveHTML ();
Output
