Let's talk about PHP GET parameter array for passing multiple parameters

You can use the GET parameter array in PHP to pass multiple parameters. Typically, GET parameters appear in the URL as key-value pairs. For example, the following URL contains a GET parameter called "name":

https://example.com/index.php?name=John

If you want to pass multiple parameters, Just add the "&" symbol after the URL and add another key-value pair:

https://example.com/index.php?name=John&age=25

When we want to receive these values, we can access the GET parameter array through $_GET. Taking the above URL as an example, using $_GET will return the following array:

Array(
    [name] => John
    [age] => 25
)

You can use the following code to output the key-value pairs in the GET parameter array:

foreach($_GET as $key=>$value){
    echo $key . ': ' . $value . '<br>';
}

Through the above code, we can The following output is obtained:

name: John
age: 25

It is worth noting that GET parameters are public, that is, they can be seen in the URL. Therefore, do not store sensitive information in GET parameters. Additionally, GET parameters are limited in length, so too much or too large data should not be stored in them.

In short, PHP supports GET parameter array for passing multiple parameters. You can use $_GET to access these parameters and manipulate them to suit the needs of your code.
