php-redisRedis scan example

while( $it !== 0 ) {
  foreach ( $redis->scan($it, 't*') as $k) {
    # do something with $k
  }
}ctrl + cgithub

`while( $it !== 0 )` we should call scan till returned iterator is not zero	`$redis` Redis object after connection
`scan` scans keys based on specified pattern and returns iterator	`'t*'` sample pattern to search keys (in this case, all keys starting with `t`)
`$it` iterator object

<?php

$r = new Redis(); 
$r->connect('127.0.0.1', 6379); 

while( $it !== 0 ) {
  foreach ( $r->scan($it, 't*') as $k) {
    echo $k . "\n";
  }
}
