Below is my php script,I am selecting data from database and then storing resultset array into redis cache using set command but not able get exactly data when I am trying to get using get command
<?php
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);
mysql_connect("localhost", "test", "testing123") or die(mysql_error());
mysql_select_db("test") or die(mysql_error());
$query = "select id from example where name = 'new_data'";
$querykey = "KEY" . md5($query);
echo $querykey;
$result = $redis->get($querykey);
echo "<pre>";
print_r($result);
if (!$result) {
$result = mysql_fetch_array(mysql_query("select id from example where name = 'new_data'")) or die('mysql error');
print_r($result);
$redis->set($querykey, $result);
print "got result from mysql\n";
return 0;
}
print "got result from redis\n";
return 0;
?>
When I do print_r($result) it gives only Array.What is the problem in approach or is there any other method to do this.
Any help appreciated. Thank you
If you want to store a result set corresponding to a key in Redis either json_encode the string or store the array result as a SET in Redis.
