Error.

Through the initial troubleshooting, I think it is because the characters are formatted in html, that is

Htmlspecialchars-Convert special characters to HTML entities.

So I tried

Htmlspecialchars_decode-Convert special HTML entities back to characters

Format it back. But the error persists.

Google found that other comrades had encountered such a problem and analyzed the reason for the quotation marks.

Pass

Stripslashes-Un-quotes a quoted string
