How can php redis respond?

Redis stores data in the memory and loses power. Pay attention to this. Make a persistence if necessary. The persistence method is hard to understand. For more information, see the article on the Internet.

Php's redis extension is called php-redis. The php-redis Chinese manual is available on the Internet. The following is an example:
<? Php $ redis = new redis (); $ result = $ redis-> connect ('2017. 0.0.1 ', 6379); // 6379 is the default port $ result = $ redis-> set ('123', "comment "); // set the key value echo $ result = $ redis-> get ('20140901'); // get the key value $ all = $ redis-> getMultiple (array ('20140901 ', '9639002718'); // obtain multiple key values at the same time // The method for obtaining all key values is not provided. I'm not sure whether it can be used. You can give it a try. $ All = $ redis-> getMultiple (array ('*'));
Thank you for your support!

 
How can I determine whether redis is suspended when php is connected to Redis?
