《PHP編程：Redis使用Eval多個(gè)鍵值自增的操作實(shí)例》要點(diǎn)：
本文介紹了PHP編程：Redis使用Eval多個(gè)鍵值自增的操作實(shí)例，希望對(duì)您有用。如果有疑問，可以聯(lián)系我們。
PHP實(shí)戰(zhàn)在PHP上使用Redis 給多個(gè)鍵值進(jìn)行自增,示例如下：
PHP實(shí)戰(zhàn)
$set['money'] = $this->redis->hIncrByFloat($key, $hour .'_money', $data['money']);
$set['ip'] = $this->redis->hIncrBy($key, $hour .'_ip', $data['ip']);
$set['uv'] = $this->redis->hIncrBy($key, $hour .'_uv', $data['uv']);
$set['pv'] = $this->redis->hIncrBy($key, $hour .'_pv', $data['pv']);
$this->redis->hSet($key, $hour, array($data['money'], $data['ip'], $data['uv'], $data['pv']));
PHP實(shí)戰(zhàn)如果這樣寫可能需要請(qǐng)求五次,可以通過 Eval 方法來一次完成,大大提高效率
PHP實(shí)戰(zhàn)
$script = 'local money = redis.call("hIncrByFloat", KEYS[1], ARGV[1], ARGV[2]);';
$script .= 'local ip = redis.call("hIncrBy", KEYS[1], ARGV[3], ARGV[4]);';
$script .= 'local uv = redis.call("hIncrBy", KEYS[1], ARGV[5], ARGV[6]);';
$script .= 'local pv = redis.call("hIncrBy", KEYS[1], ARGV[7], ARGV[8]);';
$script .= 'local val = money ..",".. ip ..",".. uv ..",".. pv;';
$script .= 'redis.call("hSet", KEYS[1], ARGV[2], val);';
$script .= 'return val;';
$result = $this->redis->evaluate($script, [$key, $hour, $hour .'_money', $data['money'], $hour .'_ip', $data['ip'], $hour .'_uv', $data['uv'], $hour .'_pv', $data['pv']], 2);
var_dump($result);
PHP實(shí)戰(zhàn)Redis 用的 Lua 語法,我也不熟悉,這個(gè)字符串拼接方式也很特別的是兩個(gè)點(diǎn)號(hào) “..”
PHP實(shí)戰(zhàn)
money ..",".. ip ..",".. uv ..",".. pv
拼接后
0.01,1,2,3
PHP實(shí)戰(zhàn)以上這篇Redis使用Eval多個(gè)鍵值自增的操作實(shí)例就是小編分享給大家的全部?jī)?nèi)容了,希望能給大家一個(gè)參考,也希望大家多多支持維易PHP.
