PHP - How to read post data with no key?
<p>This piece of jQuery code posts to one of our php pages.</p>

<pre><code>var json = '{"object1":{"object2":[{"string1":val1,"string2":val2}]}}';
$.post("phppage", json, function(data) {
    alert(data);
});
</code></pre>

<p>Inside phppage, I have to do some processing depending on the post data. But I am not able to read the post data. </p>

<pre><code>foreach ($_POST as $k =&gt; $v) {
    echo ' Key= ' . $k . ' Value= ' . $v;
}
</code></pre>
