php What should I do if I cannot import the database? php What should I do if the content in the editor cannot be inserted into the database?

When using PHP, the content in the editor cannot be inserted into the database, mainly due to the following two aspects:

1. The database design is unreasonable. For example, when using Mysql database, the inserted field type is set incorrectly. If the set field type is not large enough, it will cause overflow during insertion, and an error will occur and cannot be entered into the database.

varchar, text, mediumtext, longtext, etc. should be selected as needed.

2. There are special characters in the text of the editor, mainly single quotes ', double quotes ", single brackets (), percent signs %, and sharp angles Etc.

##These existing symbols cause statement recognition errors, so check or replace them before typing.

Replace it when output is needed.
