Does php accept post array parameters?

PHP can accept POST array parameters, because in the HTTP protocol, there are POST requests in addition to GET requests. When using POST request, when sending data from the client (browser) to the server (server), forms are often used to submit data. The data submitted by the form will be encapsulated into an array, placed in the entity of the HTTP request message, and passed to the server.

In PHP, you can use the superglobal variable $_POST to get the data submitted in the POST request. When the client sends a POST request to the server, PHP will assign the data in the POST request to the $_POST variable. Therefore, we only need to use the $_POST variable to get the data submitted in the POST request, that is, the POST array parameters.

For example, the following HTML form:

In the submit.php file, we can get the data submitted by the form through $_POST:

Through the above method, we can get the parameters of the POST array submitted by the client and process the corresponding data. However, it should be noted that when using the $_POST variable, corresponding security treatment should be carried out to avoid risks such as SQL injection.
