Php-Redis Issue

Question

I had installed Redis, Php and Php-Redis and now when i run this below program iam getting

<?php
   //Connecting to Redis server on localhost
   $redis = new Redis();
   $redis->connect('127.0.0.1', 6379);
   echo "Connection to server sucessfully";
   //check whether server is running or not
   echo "Server is running: "+ $redis->ping();
?>

The ideal output should be

Connection to server sucessfully Server is running: PONG

but the ouput iam get

Connection to server sucessfully

where could be the issue?

does echo $redis->echo('ping'); return 'ping'?

You should change this:

echo "Server is running: "+ $redis->ping();

to this:

echo "Server is running: " . $redis->ping();

Because the . operator is for Concatenation, and the + operator is for addition.

Thanks it worked. The tutorial here was wrong tutorialspoint.com/redis/redis_php.htm. Just blindly followed it.
