Text has a maximum length of 65535 (2^16-1) characters.
Mediumtext a maximum length of 16777215 (2^24-1) characters.

Upstairs two positive solutions,
Add:
1, pay attention to the string of modern deposit database.
2, the field must be a string type, including Text,varchar (must be sufficient length) and so on.
3. When you read from the database, remember to use the Htmlspecialchars function for processing. Otherwise, the received string will be HTML code.
