前言

本文主要给大家介绍了关于phpredis执行 LUA脚本的相关内容，分享出来供大家参考学习，下面话不多说了，来一起看看详细的介绍吧

示例代码

									$lua = <<<EOT

									 local kws = {}

									 local lrkws = {}

									  local nkws = {}

									  local kw_ids = {}

									  local lr_ids = {}

									  local n_ids = {}

									  for kw in string.gmatch(KEYS[1], "[^|]+") do

									   table.insert(kws, "kw:"..kw)

									  end

									  for kw in string.gmatch(KEYS[2], "[^|]+") do

									   table.insert(lrkws, "lrkw:"..kw)

									  end

									  for kw in string.gmatch(KEYS[3], "[^|]+") do

									   table.insert(nkws, "nkw:"..kw)

									  end

									  if #kws > 0 then

									   kw_ids = redis.call('sinter', unpack(kws))

									  end

									  if #lrkws > 0 then

									   lr_ids = redis.call('sinter', unpack(lrkws))

									  end

									  if #nkws > 0 then

									   n_ids = redis.call('sinter', unpack(nkws))

									  end

									  local cache_key = ARGV[1]

									  for _, v in ipairs(kw_ids) do

									   redis.call('sadd', cache_key, v)

									  end

									  end

									  for _, v in ipairs(n_ids) do

									EOT;

									 $ret = $redis->eval($lua, array("你好|谢谢", "", "hello", "cache_key"), 3);
