The connect timeout is how long PhpRedis will wait for a successful connection before timing out. $redis = new Redis;
// If this takes more than 3.5 seconds, we will throw an exception
$redis->connect('localhost', 6379, 3.5);The read timeout has to do with how long Redis takes to respond to commands once connected. <?php
$redis = new Redis;
$redis->connect('localhost', 6379);
$redis->setOption(Redis::OPT_READ_TIMEOUT, 1);
Try {
$st = microtime(true);
$redis->rawCommand('DEBUG', 'sleep', 1.5);
} catch (Exception $ex) {
$et = microtime(true);
printf("Exception: '%s' (%f seconds)\n", $ex->getMessage(), $et - $st);
}Since the $ php read-timeout.php
Exception: 'socket error on read socket' (1.001548 seconds) |

<?php$redis = newRedis;
$redis->connect('localhost', 6379);
$redis->setOption(Redis::OPT_READ_TIMEOUT, 1);
Try {
$st = microtime(true);
$redis->rawCommand('DEBUG', 'sleep', 1.5);

}
Since the DEBUG SLEEP 1.5 command takes 1.5 seconds you should see an exception:
$ php read-timeout.php
Exception: 'socket error on read socket' (1.001548 seconds)

timeout: float, value in seconds (optional, default is 0 meaning it will use default_socket_timeout)
What does the timeout of connect mean? for example, timeout is 3, means fail while connect not success in 3 seconds? or connect will disconnect after 3 seconds of idle?
