# PHP: How To Save Binary String In MySQL 5.7

## 02 March 2020 - 1 answer

How can I convert this binary string:

``````b"iphoné[email protected],;= ÑÑñe x"
``````

To normal string?

I really need to have that string as a normal string, and not as a binary string.

I am having problems saving in MySQL this binary string. If the CSV that I decode does not have ñ, é or any of this non usual characters, I dont have problem saving. But when one of this characters is set on a cell, the string appears to be binary string and I get an error when saving on MySQL this binary string.

I get this error:

``````QueryException {#1780

All tables and columns are `'utf8mb4'` and collation `'utf8mb4_unicode_ci'`
