In daily operation, I believe that many people have doubts about what problems they will encounter when transferring array data in post/get. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubts of "what problems will be encountered when post/get transfers array data?" Next, please follow the editor to study!

When using post to transfer array data, the backend first JSON the data and then transfer it to the front-end page, and then when the backend receives the data, it first htmlspecialchars_decode (change the escaped characters back), and then de-json:

Data passed to the front desk: json_encode (data)

Data received at background: json_decode (htmlspecialchars_decode (data))

Use get to pass the array to the background. In addition to the above two steps, encode the data urlencode before passing the data to the backstage, otherwise the escaped area with the & symbol will be regarded as a breakpoint.

Urlencode (data); at this point, the study on "what problems post/get will encounter when passing array data" is over, hoping to solve everyone's doubts. The collocation of theory and practice can better help you learn, go and try it!
