What is the use of strict in laravel config/databa

问题:

I am new on laravel & today I have to turn off the strict in config/database file as I need to use group by in my SQL query. What is the use of strict in laravel config/database and by turning it off or strict = false will it affect the website? Will it make our website security weak? what is the disadvantage of turning strict off in laravel config/database Thank You in advance? :)

According to the doc:

Strict mode controls how MySQL handles invalid or missing values in data-change statements such as INSERT or UPDATE. A value can be invalid for several reasons. For example, it might have the wrong data type for the column, or it might be out of range. A value is missing when a new row to be inserted does not contain a value for a non-NULL column that has no explicit DEFAULT clause in its definition. (For a NULL column, NULL is inserted if the value is missing.) Strict mode also affects DDL statements such as CREATE TABLE.

Disabling it wouldn't make your website unsecured if you handle all validations in your controllers and follow best practices like Laravel already does out of the box.
