带有方括号的表单输入名称不是PHP中的数组

Question

I have a form like this:

<form action='http://zzz.com' method='post'>
    <input name='fruit[1]' value='apple' />
    <input name='fruit[2]' value='banana' />
</form>

on the server side this should be an array.

assert( $_POST['fruit'] === array(1=>'apple', 2=>'banana') );

In my case it is an empty string !!??!!

assert( $_POST['fruit'] === '' );

I have no idea what the problem is - never seen this before. Anyone can help plz?

PHP 5.5.12

Answer 1

use like this...

<form action='' method='post'>
    <input name='fruit[1]' value='apple' />
    <input name='fruit[2]' value='banana' />
    <input type="submit" name="btn" value="OK" />
</form>
<?php
print_r($_POST['fruit']);
?>

after submitting ok button it will show you complete array
