从数组列表中获取表单序列化值

Question

I have an array like this:

Array
(
    [action_name] => edit
    [formData] => color=red&size=full&symmetry=square
)

Here, form data is coming using the serialize method of JS and so it is displayed like above. I want to get each data from the formData key. How can I get that?

I tried:

$_POST['formData']['color']

But that is not working. I think the method to fetch this shall be different. How can I do that?

Answer 1

You can use parse_str to " parse string as if it were the query string passed via a URL and sets variables in the current scope (or in the array if result is provided). "

<?php
$myArray = [
    "action_name" => "edit",
    "formData" => "color=red&size=full&symmetry=square",
];
parse_str($myArray['formData'], $parsed);
print_r($parsed);

will output

Array
(
    [color] => red
    [size] => full
    [symmetry] => square
)
