How to retrieve data values when sending a post request with php?

To send a POST request and retrieve data values in PHP, follow these steps:

1. You can use the $_POST superglobal variable to retrieve data values from a POST request. For example, if there is a data value called “username” in the POST request, you can use $_POST[‘username’] to retrieve that value. For example:

$username = $_POST['username'];

1. Use the file_get_contents function to retrieve the raw data of a POST request, and then use the parse_str function to parse it into an associative array. For example:

$postData = file_get_contents('php://input');
parse_str($postData, $postArray);

You can then use the $postArray array to access the data values in the POST request. For example, if there is a data value named “username” in the POST request, you can use $postArray[‘username’] to retrieve that value. For example:

$username = $postArray['username'];

Please note that the above method is only effective when the Content-Type of the POST request is application/x-www-form-urlencoded. If the Content-Type of the POST request is a different type (such as application/json), then other methods may need to be used to retrieve the data values based on the specific situation.
