Does POST request support array storage in PHP?

Does POST request in PHP support array storage?

In PHP, POST requests support array storage. When submitting data through a form, you can use arrays to pass multiple values ​​to the server. This method is very practical and especially convenient when processing complex form data.

Let’s look at some specific code examples to demonstrate how to use POST requests to pass array data in PHP:

Example 1: Submitting an array through a form

<form method="post" action="process.php">
    <input type="text" name="info[name]">
    <input type="text" name="info[email]">
    <input type="number" name="info[age]">
    <input type="submit" value="提交">
</form>

In In the above form, we use info[name], info[email], info[age] as the name attribute of the form element, forming An array named info.

Example 2: Processing array data in POST requests

<?php
if($_SERVER['REQUEST_METHOD'] == 'POST') {
    $name = $_POST['info']['name'];
    $email = $_POST['info']['email'];
    $age = $_POST['info']['age'];

    echo "Name: " . $name . "<br>";
    echo "Email: " . $email . "<br>";
    echo "Age: " . $age . "<br>";
}
?>

In the above PHP code, we pass $_POST['info']['name'] method to obtain the array data passed in the POST request.

Example 3: Using foreach loop to traverse the array

<?php
if($_SERVER['REQUEST_METHOD'] == 'POST') {
    $info = $_POST['info'];

    foreach($info as $key => $value) {
        echo $key . ": " . $value . "<br>";
    }
}
?>

Through the above example, we can see that it is quite simple and convenient to pass array data through POST request in PHP. This method can greatly simplify the code writing and data processing process, and is especially suitable for processing form submissions. In actual development, we can flexibly use this technique to handle complex data interaction requirements and improve development efficiency and code maintainability.
