Select data from table using REDISQL in Redis - php

Question

I have install Redis in Ubuntu 16.04.6 successfully.
Here is the demo code for set and get value in redis.
<?php
//Connecting to Redis server on localhost
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);
//set the data in redis string
$redis->set("tutorial-name", "Redis tutorial");
// Get the stored data and print it
echo "Stored string in redis:: " .$redis->get("tutorial-name");
?>
And I have got correct output as below.
# php redis.php
Stored string in redis:: Redis tutorial
Now I want to store some value in redis with SQL so I configure Redis with RedisSQL and it configures correctly and working fine with a command line.
I have create one DB and insert one record for testing.
Here is the output of the SQL select query in Redis.
# redis-cli -p 6379
127.0.0.1:6379> REDISQL.EXEC DB "SELECT * FROM foo;"
1) 1) (integer) 3
2) "bar"
Now I want to try to get the same query result in PHP script so I search for this and find like using rawcommand to get command output in redis so I tried using the same command as below.
<?php
//Connecting to Redis server on localhost
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);
$result = $redis->rawCommand('REDISQL.EXEC', 'foo', 'SELECT * FROM foo;');
echo "Foo table Data:";
print_r($result);
?>
But get $result value blank.
# php redis.php
Foo table Data:
#
So can anyone guide me to get the correct result for SQL query, with rawCommand or any other command?
Thanks in advance.

Try to give the select statement in double quotes
$result = $redis->rawCommand("REDISQL.EXEC", "foo", "SELECT * FROM foo");
