The following code filters html information such as htmlentities ().

In the following code, how to filter html such as htmlentities () is to filter the keyword, that is, to filter the search content entered by the user out of the html code, my younger brother doesn't know much about php. thanks for public & nbsp; function & nbsp; search () {global & how can I filter html such as htmlentities () in the following code?

It should be to filter the keyword, that is, to filter out the html code of the search content entered by the user
If you have trouble, give the code directly. The younger brother doesn't know much about php. thank you.

If your code is okay! Just add a strip_tags function!

Public function search ()
{
Global $ _ FANWE;

$ Page_args = array (
'City _ PY' => CURRENT_CITY_PY,
'Sort '=> trim ($ _ FANWE ['request'] ['sort']),
'Keyword' => strip_tags (trim ($ _ FANWE ['request'] ['keyword']),
); // Add a strip_tags.

$ Keyword = '';
If (! Empty ($ page_args ['keyword'])
