Passing dynamic input field array item values with different names to php

Question

I'm using this form from formvalidation.io:

<form id="bookForm" method="post" class="form-horizontal">
<div class="form-group">
    <label class="col-xs-1 control-label">Book</label>
    <div class="col-xs-4">
        <input type="text" class="form-control" name="book[0].title" placeholder="Title" />
    </div>
    <div class="col-xs-4">
        <input type="text" class="form-control" name="book[0].isbn" placeholder="ISBN" />
    </div>
    <div class="col-xs-2">
        <input type="text" class="form-control" name="book[0].price" placeholder="Price" />
    </div>
    <div class="col-xs-1">
        <button type="button" class="btn btn-default addButton"><i class="fa fa-plus"></i></button>
    </div>
</div>

The input field names are very special, e.g. name="book[0].title".

How to pass all these input field array values to my php script?

I guess the "." is not php compliant. Changing the names in a way like name="book[0][title] leads to error messages like Warning: Illegal string offset 'title' in www/... with print_r($_POST['book'][0]['title']);.

I appreciate any help!

You have to use print_r($_POST[books][0][title]); instead, hope it helps. Also, is it 'book' or 'books'? That could bring an error too. But my point is that you don't have to use ' delimiter.

Below format should work

<input type="text" class="form-control" name="book[0][title]" placeholder="Title" />

When you print_r($_POST) you will get the submitted data in proper array format. And you can also get the title by using $_POST['book'][0]['title']

[book] => Array
        (
            [0] => Array
                (
                    [title] => titletext
                    [isbn] => isbntext
                    [price] => 100
                )

        )
