Processing of javascript-post and displaying special characters

{Code...} displays the result as follows: OK. The problem arises. When I enter a general character in the input box, save it to the database, and finally retrieve it in the input box, there is no problem. When a special character such as & #039; & quot; & amp; lt; & amp; gt; is entered, although it is included in the php retrieval and retrieval process...

Data "/>

The displayed result is as follows:

Okay, the problem is. When I enter a general character in the input box, save it to the database, and finally retrieve it in the input box, it is okay.

When the input example is '"<> this special character, although \ and \ are added during php acquisition and removal \, however, these characters will still be displayed in the input, which will lead to disorder in the html format.

In my current practice, replace the English and "with the Chinese" and ", and then replace them with escape characters when receiving post, for example:

<Less than or show Mark> greater than or show Mark & can be used to display other special characters "" quotation marks

But it is never the best solution. Could you tell me:

1. How can I solve the problem?

2. What should I do in an editor such as kingeditor and fck?

Escape when output
htmlspecialchars()

Obviously, you should not escape it like this.

You should convert double quotation marks"Such characters.

Close the post by yourself:
1. Use addslashes () to add a slash to a special character before writing SQL.
2. After SQL is extracted, use tripslashes () to slash special characters
3. When html is output, use htmspecialchars () to convert special characters into html Escape characters.
