Inserting UTF-8 encoded string into UTF-8 encoded mysql table fails with “Incorrect string value”

Question

Inserting UTF-8 encoded string into UTF-8 encoded table gives incorrect string value.

PDOException: SQLSTATE[HY000]: General error: 1366 Incorrect str

Answer 1

I fixed the error: SQLSTATE[HY000]: General error: 1366 Incorrect string value ...... with this method:

I use utf8mb4_unicode_ci for database Set utf8mb4_unicode_ci for all tables

Set longblog datatype for column (not text, longtext.... you need big datatype to store 4 bytes of your content)

It is okay now. If you use laravel, continue to edit config/database.php

'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',

If you use function strtolower, replace it with mb_strtolower Notice: you have to put on your head tag
