MySQL query working in phpmyadmin but not in php - php

Question

I want to select data from a table in MySQL.
My code in php:
$conn = mysqli_connect($db_server, $db_benutzer, $db_passwort, $db_name);
$results= mysqli_query($conn, "SELECT * FROM `test` WHERE russia = 'привет'");
if(mysqli_num_rows($results) > 0) {
echo "Results";
}
else {
echo "No results";
}
mysqli_close($conn);
Here I'm getting "No results". But when I run the SELECT-code directly in phpmyadmin i get a result.
What's wrong?
Thank you

Answer 1

You have cyrillic characters in your query, so it may be necessary to set mySQL connection encoding. If you are using utf-8, insert following line after mysqli_connect:
mysqli_query($conn, "SET NAMES 'utf8'");
Or if your script is saved in windows-1251, use the following: mysqli_query($conn, "SET NAMES 'cp1251'");
For more information about connection character sets and encodings please see the manual
And why does the query work in phpMyAdmin? Because it probably sets encoding for you in the background.

Answer 2

You won't get 0 results in any way,you either get results or no results.
2.try removing the quotes from the table name
Check for any Encoding issues with the connection encoding and that the data on the value of column russia is parsed as something else.
Try executing the following query before executing your main query
mysqli_query($conn,"SET character_set_results='utf8',character_set_client='utf8',character_set_connection='utf8',character_set_database='utf8',character_set_server='utf8'");
The problems arise if there are Encoding issues in the connection.
