Deprecated: Function Redis::delete() is deprecated

PHP 操作 Redis 时遇到如下的问题

Deprecated: Function Redis::delete() is deprecated



原因：php-redis 5 版本弃用了 Redis::delete()

php -r 'phpinfo();'



运行上述命令在输出中找到 redis，看到为 5.0.1 版本





解决方法：将 delete($key) 改成 del($key) 的操作即可

附：被弃用的方法名的解决

被弃用方法名    替代方法名

delete    del

zUnion    zunionstore

zInter    zinterstore

zDeleteRangeByRank    zRemRangeByRank

zDeleteRangeByScore    zRemRangeByScore

参考：

https://www.drupal.org/project/redis/issues/3068810 this is caused by the update to php-redis 5, apparently only in the PHP 7.3 images. 这是由于更新至 php-redis 5 版本后所造成的，很明显只会在 PHP 7.3 出现

https://github.com/phpredis/phpredis/pull/1588 all aliases are deprecated & delete is an alias for del 所有的别名被弃用 & delete 之前是作为 del 的别名

https://pecl.php.net/package-changelog.php?package=redis&release=5.0.0 Soft deprecate methods that aren't actually Redis commands [a81b4f2d, 95c8aab9] 被弃用的方法实际上并不是 Redis 本身自带的命令
