从$ _POST填充PHP多维数组

Question

I have to build an array as the following one gathering values from $_POST superglobal. ca_objets value would be gather from a variable and the part after the dot is what I need to gather from $_POST.

 $va_body=array(
        "bundles" => array(
            "ca_objects.description" => array("convertCodesToDisplayText" => true),
            "ca_objects.description" => array("convertCodesToDisplayText" => true),
            "ca_object.representations.caption" => array("convertCodesToDisplayText" =>  true)
        )
    );

This is the code I use:

<?php
$table="ca_objects";
$bund=$_POST['find_bundles']; //This is an array with the values I need.

$va_body=array("bundles" => array()); //I declare the array outside the foreach loop. 

I'm not sure how to code the loop in order to populate the "bundles" array inside $va_body array and get the result I need. Any help will be greatly appreciated.

   foreach ($bund as $elem ) {
    // code here
        }

    ?>

You can just access the array by its associative key, like this:

foreach ($bund as $elem ) {
    // code here
    // The empty square brackets tells php to push the $elem value into the next available array key
    $va_body['bundles'][] = $elem;
}
