About PHP recursive array code analysis_PHP tutorial

We all know that PHP is an HTML embedded language. PHP is quite similar to Microsoft's ASP. They are both scripting languages ​​that are executed on the server side and embedded in HTML documents. The language The style is similar to C language and is now 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 "formal database for online operation" and the "test database for development and debugging".

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 Using the a.php program to write the "formal database" and "test database" at the same time will inevitably affect the formal services running online. So, I thought of using the PHP curl extension library to post a copy of the generated $data array to the PHP program, and then the PHP program continued to execute the code to write the "formal database". The PHP program passes the $data array to the PHP program and that's it. As for how PHP handles it, it has nothing to do with PHP. Even if the PHP program fails to write the "test database", it will not have an impact on the PHP program.
