PHP recursive array code analysis

We all know that PHP is an embedded HTML language. PHP is similar to Microsoft's ASP, and it is a script language that is executed on the server to embed HTML documents, the language style is similar to the C language and is widely used by many website programmers. This article introduces PHP recursive arrays in detail. The PHP program needs to write the received data to both the "official database running online" and the "test database for development and debugging ".

However, the test database may often face problems such as adjusting the table structure, fields, and configuration information. It is very unstable and has a high probability of errors. If a is used. php programs write "official database" and "Test Database" at the same time, which will inevitably affect the official services running online. So I want to use the PHP curl extension library to pass the generated $ data array post to the php program, and then the php program continues to execute the code to write the "official database. The php program will pass the $ data array to the php program. As for how php is handled, it will not be related to php. Even if the php program fails to write "Test Database, it will not affect the php program.
